4. Connect a Detector
Do not connect more than one detector to the power meter at any time.
Refer to the drawing of the S310 rear panel in Figure 1. A 3-meter mini-DIN type cable with "D" shaped
connectors comes with Vector calorimeters, including the large aperture calorimeters. A 3-meter BNC
type cable comes with Vector pyroelectric detectors and Vector HR pyroelectric detectors. To connect the
Vector detectors, the input connectors on the rear panel of the S310 are labeled as follows:
"Ultra" for Ultra Detectors (no longer manufactured)
"Vector" for all Vector Pyroelectric detectors
"Astral” for all Vector calorimeters, including the large aperture calorimeters
Note that the flat side of the DIN type cables should be oriented up when plugging into the S310.
Detectors have a 1/2" diameter mounting post hole for installing a detector post. Mounting bases and posts
are available for purchase at Scientech to attach the detector to a working surface.
5. Select a Range
On the first press of the RANGE button, the analog scale (if active) will disappear. Then briefly press the
RANGE button each time another range is desired. Press the SELECT button when the range you desire
appears in the display (failure to press the SELECT button within 3 seconds will activate the range shown
in the display and return the S310 to its operation state).
6. Select a Mode
The MODE button allows selection of the type of measurement to be made (watts, joules, etc). It also
gives access to the scientific notation unit of measure. The different measurement modes available are:
A. When configured for a pyroelectric detector: Energy (J), Avg. Energy (J AVG), Power (W AVG),
and Volts (V).
B. When configured for a calorimeter: Power (W AVG), Energy (J).
Briefly press the MODE button each time a different mode setting is wanted. Press the SELECT button
when the mode you desire appears in the display (failure to press the SELECT button within 3 seconds
will activate the mode shown in the display and return the S310 to its operation state).

Direct the laser beam onto the absorbing surface of the detector.
GROUP SETTINGS
The operating parameters for the detectors used with the S310 power meter must be stored in the power
meter’s memory. This information is stored in Group Settings. The typical configuration of the Group
Settings is as follows:
Group #1 – Vector Calorimeters or Large Aperture Calorimeters
Group #2 – Vector Pyroelectric Detectors
Group #3 – Vector HR Pyroelectric Detectors
However, the Group Settings may be configured differently depending on what detectors are used with
the power meter. The operating parameters and group number for the detectors purchased with the S310
Power meter are recorded on page 2 of this manual.
To Select a Group
A. Press the SETUP button. The Group Setting last used will appear in the display.
B. To move to the next Group, press SETUP button again.
C. To select a Group, press the SELECT button when the Group you desire appears in the display
(failure to press the SELECT button within 3 seconds will activate the Group shown in the display
and return the S310 to its operational state).
Group Settings for VectorCalorimeters
The factory default Group for Vector 8mm, 25mm, 16mm, 50mm or large aperture calorimeters is Group
#1.
Note: Pressing the CANCEL button at any time during this process will terminate this process with no
changes made.
Note: Holding down the SELECT button for 3 seconds at any time during this process will save any
changes made up to that point and return the S310 to its operational state for the Group selected.

To review, change, or setup a Group Setting for Vector calorimeters, proceed as follows:
A. Press the SETUP button. The Group Setting last used will appear in the display.
B. To move to the next Group, press SETUP button again.
C. To select a Group, press the SELECT button when the Group you desire appears in the display
(failure to press the SELECT button within 3 seconds will activate the Group shown in the display
and return the S310 to its operational state).
D. Press the SETUP button until the calorimeter annunciator “CAL” appears in the display. Press the
SELECT button to activate the calorimeter configuration program.
E. The "tc" (time constant) annunciator now appears in the display. The time constant is a measure
of the length of time the calorimeter takes to respond to a laser beam.
Press the countup (RANGE)and count down (MODE) buttons to changethe numberinthe display
to match the time constant number listed on the serial tag of your Vector calorimeter or interface
module for large aperture calorimeters. Press the SELECT button to enter the time constant value
to memory.
F. The "SP" (speed) annunciator now appears in the display. The speed setting allows you to control
the power meter’s display rate. The best value will cause a slight overshoot then a quick settling
on the final value. Too high of a setting will cause the display to overshoot then slowly drift back
down to the final value. A slow setting will cause the display to slowly count up to the final value.
Press the count up (RANGE) button to speed up or count down (MODE) button to slow down the
response time of the meter. Press the SELECT button when the desired number appears in the
display. The following settings can be fine tuned to your preference of speed versus overshoot. We
recommend these initial settings:
AC2500, AC25HD, ACX25HD 103.0
AC2501, ACX2501, AC25UV, AC2504, AC25FX, ACX25FX 136.0
AC5000, AC50HD ACX50HD, AC50FX, ACX50FX 100.0
AC5001, ACX5001, AC50UV, AC5004, 120.0
360401 with interface module 150.0
380401, 380402, 384UV5 with interface module 245.0
360801 with interface module 170.0
380801, 380802, 388UV5 with interface module 280.0
G. The "Cd" (calorimeter delay) annunciator now appears in the display. The calorimeter delay
feature prohibits the display of energy if a pulse is fired before the entered time (1 to 255 seconds)
elapses. The calorimeter must reach environmental thermal equilibrium before a subsequent pulse
is fired or low energy measurements will occur.

PN10190T 11
To set the time delay between pulses use the count up (RANGE) and count down buttons (MODE)
buttons to enter the time in seconds. Press the SELECT button after the time has been entered to
save the setting. The following time delays are recommended:
AC2500, AC25FX, ACX25FX, AC25HD, ACX25HD 60 seconds
AC2501, AC25UV, AC2504 60 seconds
AC5000, AC50FX, ACX50FX, AC50HD, ACX50HD 90 seconds
AC5001, AC50UV, AC5004 90 seconds
360401 with interface module 105 seconds
380401, 380402, 384UV5 with interface module 180 seconds
360801 with interface module 125 seconds
380801, 380802, 388UV5 with interface module 200 seconds
H. The "At" (attenuation) annunciator now appears in the display. If no attenuator is being used in
conjunction with the calorimeter, the attenuation factor in the display must be set at 1.000 since
this value is a display multiplier. Attenuation multipliers from .0001 to 9999 can be entered into
the displayed value.
The attenuation factors of optics can be entered into the S310 so the displayed value will
automatically compensate for the amount of attenuation. For example, assume a beam splitter is
being used that transmits 75% and reflects 25% of the beam. If the S310 is set up to measure the
reflected beam the attenuation could be set up as follows:
•An attenuation factor of 1 would display the value of the reflected beam.
•An attenuation factor of 3 would display the value of the transmitted beam.
•An attenuation factor of 4 would display the value of the source.
Use the count up (RANGE), count down (MODE) buttons to change the attenuation factor. Press
the SELECT button to enter the attenuation factor to memory.
I. If the S310 has the optional IEEE488 interface, the REMOTE annunciator will appear along with
the digital interface previously selected; r232 (RS232) or IEEE (IEEE488). Press the SETUP
button to toggle the interface between r232 (RS232) and IEEE (IEEE488). Press the SELECT
button when the desired interface appears in the display.
J. If the optional IEEE488 interface was not installed, the "br" (baud rate) annunciator for setting up
the RS232 interface appears in the display along with the baud rate previously selected. To change
the baud rate press SETUP button until the desired baud rate appears in the display. One of the
following baud rates can be selected: 300, 1200, 2400, 9600, and 19,200. When the preferred
baud rate appears in the display press the SELECT button.
K. The "PA" (parity) annunciator now appears in the display. Press the SETUP button to select none,
even, or odd parity. Press the SELECT button to enter the parity of choice to memory

PN10190T 12
L. The "HS" (handshake) annunciator now appears in the display. Press the SETUP button until your
choice of none (nOnE), on/off (onoF), or clear to send (CtS) appears in the display. Press the
SELECT button when your choice is displayed to enter the handshake to memory.
M. If IEEE488 has been selected, the "bA" (bus address) annunciator appears with the default bus
address. Bus addresses from 0 to 30 may be selected by pressing the count up (RANGE) count
down (MODE) buttons followed by the SELECT button. Once the remote interface has been setup,
the group annunciator will appear. Press the SELECT button or simply wait a few seconds and
the group will automatically be selected for operation.
Group Settings for VectorPyroelectric Detectors
Note: The factory default Group for Vector Pyroelectric Detectors is Group #2.
Note: The factory default Group for Vector HR Pyroelectric Detectors is Group #3.
Note: Pressing the CANCEL button at any time during this process will terminate this process with no
changes made.
Note: Holding down the SELECT button for 3 seconds at any time during this process will save any
changes made up to that point and return the S310 to its operational state for the Group selected.
Note: If you want to use the transfer calibration function, you must select the watts mode prior to entering
the Group configuration program.
To review, change, or setup a Group Setting for Vector Pyroelectric or Vector HR Pyroelectric detectors,
proceed as follows:
A. Press the SETUP button. The Group Setting last used will appear in the display.
B. To move to the next Group, press SETUP button again.
C. To select a Group, press the SELECT button when the Group you desire appears in the display
(failure to press the SELECT button within 3 seconds will activate the Group shown in the display
and return the S310 to its operational state).
D. Press the SETUP button until the "PYro" annunciator appears. Immediately press the SELECT
button to select the pyroelectric detector configuration program.
E. Either the "V/J" annunciator or the "V/mJ" annunciator and a detector sensitivity number will
appear in the display. V/J is used for standard pyroelectric detectors. V/mJ is used only for HR
pyroelectric detectors. Press the SETUP button to toggle between the V/J and V/mJ entries. The
output sensitivity of the pyroelectric detector in V/J or V/mJ is listed on the serial tag of your
detector. Use the count up (RANGE) and count down (MODE) buttons to enter the V/J or V/mJ
value. Press the SELECT button to enter the value to memory. Do not push the SELECT button

PN10190T 13
before entering the sensitivity number as this takes you to the next setup step without the proper
sensitivity number.
F. The "SP" (speed) annunciator now appears in the display. Press the SETUP button to toggle
between bL (black or HD coated detectors) or hF (high frequency) detector. If the detector Model
No. includes the letters “HF”, press the SELECT button when the hF annunciator appears in the
display. If the detector’s surface is black (does not have the letters “HF” in the Model No.) press
the SELECT button when the "bL" annunciator appears in the display.
G. The "AUTO, SET CAL" annunciators now appear in the display (only if watts mode was selected
prior to group configuration). This is the Transfer Calibration function. The Transfer Calibration
function is designed to transfer the calibration from a NIST certified calorimeter to a Vector
pyroelectric detector. This function allows you to adjust the output sensitivity of your Vector
pyroelectric detector in combination with your S310 meter (in the average power mode) in order
to match the average power reading of a NIST certified system. Typically, a 50/50 beam splitter
is used with the Vector pyroelectric detector to be calibrated in one beam path and the NIST
certified calorimeter in the other beam path. You are to adjust the output sensitivity of the
pyroelectric detector while it is operating by using the count up (RANGE), count down (MODE)
buttons, which change the V/J or V/mJ settings, to make the displayed value of the S310 power
reading the same as the NIST standard. Press the SELECT button when the readings match.
H. The "At" (attenuation) annunciator now appears in the display. This allows you to enter a value
from 0.0001 to 9999 which will become a multiplier of the actual displayed value. If no attenuator
or correction factor is to be used in conjunction with the pyroelectric detector then the attenuation
factor must be set to 1.000.
The attenuation factors of optics can be entered into the S310 so the displayed value will
automatically compensate for the amount of attenuation. For example, assume a beam splitter is
being used that transmits 75% and reflects 25% of the beam. If the S310 is set up to measure the
reflected beam the attenuation could be set up as follows:
•An attenuation factor of 1 would display the value of the reflected beam.
•An attenuation factor of 3 would display the value of the transmitted beam.
•An attenuation factor of 4 would display the value of the source.
Use the count up (RANGE), count down (MODE) buttons to enter the attenuation value. Press
the SELECT button to enter the value to memory.
I. The REMOTE annunciator now appears along with the digital interface previously selected; r232
(RS232) or IEEE (IEEE488). Press the SETUP button to change the interface between r232
(RS232) and IEEE (IEEE488). Press the SELECT button when the desired interface appears in
the display.
J. If RS232 has been selected, the "br" (baud rate) annunciator appears in the display along with the
baud rate previously selected. To change the baud rate press the SETUP button repeatedly until
the desired baud rate appears in the display. One of the following baud rates can be selected: 300,

PN10190T 14
1200, 2400, 9600, and 19,200. When the preferred baud rate appears in the display press the
SELECT button.
K. The "PA" (parity) annunciator now appears in the display. Press the SETUP button to select none,
even, or odd parity. Press the SELECT button to enter the parity choice to memory
L. The "HS" (handshake) annunciator now appears in the display. Press the SETUP button until your
choice of none (nOnE), on/off (onoF), or clear to send (CtS) appears in the display. Press the
SELECT button when your choice is displayed to enter the handshake to memory.
M. If IEEE488 has been selected, the "bA" (bus address) annunciator appears with the default bus
address. Bus addresses from 0 to 30 may be selected by pressing the count up (RANGE) count
down (MODE) buttons followed by the SELECT button. Once the remote interface has been setup,
the group annunciator will appear. Press the SELECT button or simply wait a few seconds and
the group will automatically be selected for operation.

Figure 3. Pyroelectric Spectral Response
Before using your Vector joulemeter system, please review the energy density formulas given in the chart
at the front of this manual. Familiarize yourself with all of the specifications of the detector models which
you are using. A damage test slide is provided with each P and PHF type detectors, but not with PHD
type detectors. Fire the beam at the test slide before using the detector to be sure you are operating under
safe conditions.
The default Group Setting for Vector Pyroelectric Detectors is Group #2. The default Group Setting for
Vector HR Pyroelectric Detectors is Group #3. Either select Group #2, #3, or configure another Group
for pyroelectric detectors and select that Group. For Group configuration, refer to the Group Settings
section.
Note: The automatic trigger threshold of the S310 is 7 % of full scale.
1. To Turn On the Meter
Note: For the most accurate measurements possible, the S310 should be turned on and warmed up for 30
minutes.
Press the ON switch located in the rear panel of the meter. The S310 will immediately turn on with its
operational state based on the last used detector Group Setting. If you purchased the S310 with one
detector, this detector’s Group settings will be active and you are ready to take measurements.
If you purchased more than one detector with the S310, you must choose the Group setting for the detector
you are connecting to the S310 as described in step 4. The Group Setting for each detector purchased
with your S310 is shown on page 2.

2. To Turn the Analog Needle On or Off (does not apply to the S310D)
To turn the analog meter on or off, press and keep holding the RANGE button down. Then release after
the meter appears or disappears.
3. To Zero the Analog Needle (does not apply to the S310D)
Refer to Figure 3. The black slotted button located just below the display allows screwdriver adjustment
to set the analog needle to zero. This adjustment should be made before connecting a pyroelectric detector.
4. To Connect a Pyroelectric Detector
Note: Only one detector should be plugged in at any time.
Refer to the drawing of the S310 rear panel in Figure 2. A 3 meter BNC type cable comes with Vector
pyroelectric detectors and Vector HR pyroelectric detectors. One of the input connectors on the rear panel
of the S310 is labeled "Vector" for hook up of the pyroelectric detectors.
5. To Select a Group
A. Press the SETUP button. The Group Setting last used will appear in the display.
B. To move to the next Group, press SETUP button again.
B. To select the appropriate Group, press the SELECT button when the Group you desire appears in
the display (failure to press the SELECT button within 3 seconds will activate the Group shown
in the display and return the S310 to its operational state).
6. To Select a Range
Note: AUTO range may be selected if the energy levels of repetitive pulses are to be measured. However,
do not select AUTO range if you want to measure single pulse energy or pulses running at repetition rates
lower than 10 Hz.
A. Press the RANGE button. On the first press of the RANGE button, the analog scale (if active) will
disappear. Then briefly press the RANGE button each time another range is desired.
B. To select a range, press the SELECT button when the range you desire appears in the display

7. To Select a Mode
Available pyroelectric modes are: Energy (J), Avg. Energy (J AVG), Average Power (W AVG), and
Volts (V).
A. To Measure Energy (J):
Note: The update rate of the display is 20Hz.
i. Press the MODE button (repeatedly, if necessary) until the “J” annunciator appears in the
display.
ii. Press the SELECT button (or wait 3 seconds) and the joules mode will automatically be
activated.
iii. The energy level of each laser pulse will be displayed on the LCD.
B. To Measure Average Energy (J AVG)

PN10190T 18
Note: The maximum repetition rate for average energy is 300Hz.
i. Press the MODE button (repeatedly, if necessary) until the “J AVG” annunciator appears in
the display.
ii. Press the SELECT button (or wait 3 seconds) and the average joules mode will be
automatically activated. The number of pulses to be averaged will now appear in the display.
You may select the number of pulses to average from 2 to 9999.
iii. To change the number of pulses to be averaged, press the RANGE (count up) and/or MODE
(count down) buttons. When the desired number of pulses to be averaged appears in the
display, press the SELECT button.
iv. The average energy of the number of pulses you selected will be displayed after the number of
pulses entered in step ii is received by the pyroelectric detector. This is not a running average,
but is the average for the pulse population selected in step ii. Nothing is displayed until the
full pulse population is delivered. This average is displayed until another full population of
pulses is delivered at which time the display is updated with the average for that population of
pulses.
C. To Measure Average Power (W AVG)
Note: The maximum repetition rate for average power is 300Hz. The minimum repetition rate for average
power is 10Hz.
Note: The average power mode displays the average power (watts) of repetitively pulsed lasers.
Pyroelectric detectors will not work with continuous wave lasers.
i. Press the MODE button repeatedly until the “W AVG” annunciator appears.
ii. Press the SELECT button (or wait 3 seconds) and the S310 will automatically enter into its
operational state in the average power mode.
iii. The average power will be displayed.
D. To Measure Volts (V)
Note: The maximum repetition rate for volts is 300Hz.
i. Press the MODE button repeatedly until the “V” annunciator appears.
ii. Press the SELECT button (or simply wait 3 seconds) and the S310 will automatically enter
into its operational state in the volts mode.
iii. The volts per pulse will be displayed.
8. To Measure a Statistical Run of Energy Pulses

PN10190T 19
Note: Do not use AUTO range when making a statistical run.
Note: Do not go from the Average Power Mode to Stats since the range will be too high. Select the range
manually.
Note: When using the PHF09 pyroelectric detector in the long pulse setting, a manual range must be
selected when running statistics.
Note: Each time a new stats run begins, data from the previous run is lost. If statistical data is to be saved,
it must be done though the digital interface.
Note: To exit the statistical mode at any time, press the CANCEL button.
Note: Statistics mode can collect data at repetition rates of up to 750 Hz depending on the detector model.
The statistics mode will collect data on a pulse population of up to 1000 pulses. At your prompting, the
power meter will display the number of pulses delivered, average energy, minimum energy, maximum
energy, standard deviation, and coefficient of variation. When the statistics mode is selected, the energy
mode is automatically activated regardless of the mode previously selected. Select the appropriate range
for the pulse energy level to be measured. It is very important to select the most appropriate range. If you
have selected a manual range and the laser pulse(s) has overflowed the maximum energy of the range, OF
will be displayed when the data is recalled. You should then select a higher range.
To enter into the statistics mode:
A. Press the STATS button. The number of pulses in the last statistics run will appear in the display.
B. Use the RANGE (count up) and MODE (count down) buttons to change the display to the desired
number of pulses to include in the statistics run (up to 1000).
C. Press the SELECT button to enter the pulse population to memory.
D. Press the SELECT button to begin the run. The power meter will automatically stop once the data
has been collected.
B. Press the STATS button to recall the data to the display. The STATS button must be pressed each
time to recall each of the following statistical calculations:
Number of pulses collected
Average energy (AVG)
Minimum energy (MIN)
Maximum energy (MAX)
Standard deviation (SIGMA)
Coefficient of variation (CV%)

PN10190T 20
F. After recalling the statistical information, the flashing STATS annunciator indicates that the S310
is ready for a new run.
A. Press the SELECT button to start a new run (each time a new run begins, data from the previous
run is lost) or press the CANCEL button to return the power meter to the mode of operation in
effect prior to statistics mode.
9. External Trigger
The automatic trigger threshold of the S310 is 7 % of full scale. The external trigger function is designed
for single pulse energy measurement with a calorimeter. It does not improve the trigger circuit of the
S310 with pyroelectric detectors.
To Perform a Transfer Calibration
You can transfer a calibration from a calorimeter to a Vector pyroelectric detector using the Transfer
Calibration function of the S310. To do this, please refer to the Group Settings for Vector Pyroelectric
Detectors, paragraph #G. You must follow the Group Settings steps to get into the Transfer Calibration
function. This function allows you to adjust the output sensitivity of your Vector pyroelectric detector in
combination with your S310 meter in order to match the average power reading from the S310 to that of
a NIST certified system. Typically, a 50/50 beam splitter is used with the Vector pyroelectric detector to
be calibrated in one beam path and the NIST certified calorimeter in the other beam path.
HR Battery Installation
A 9 Volt alkaline battery comes installed with all HR Series detectors. Always select the OFF position
of the power switch when the detector is not in use to spare the lifetime of the battery. Replace the battery
when the low battery LED indicator lights up.
