CAUTION: SPECULAR REFLECTION
NOTE: Please exercise caution when using HD detectors. They exhibit spectral reflection of between
7% and 33%, of the input power, back out of the aperture. Please refer to the preceding bar graph to
determine the reflectance for the wavelength you are measuring. These detectors should be treated as a partial
mirror or any other type of reflective optic and the appropriate caution level observed, especially at the CO2
wavelength.

ENVIRONMENTAL REQUIREMENTS
This product is intended for indoor use at altitudes up to 2000 meters, Pollution Degree 2 in accordance with
IEC 664 and transient overvoltages according to Installation Categories (Overvoltage Categories) II. Note that
each of the above detectors will not pass the IEC 801 Publication, Part 3, Radiated Electromagnetic Field
Requirements. The system, meter and detector, is designed to measure radiation within the test's radiation
band. The detectors were held outside the radiated electromagnetic field during this test. It is up to the user
to be aware of RF fields present during measurements and their effects if any on those measurements.
UNPACKING AND SETUP
The meter, detectors, and accessories are shipped in custom packing materials. All packing materials should
be saved for future damage free shipments. Before making any connections, verify that the power (VAC)
requirement shown on the power entry module is compatible with the actual AC power outlet to which the
indicator will be connected. insert into the fuse holder. Plug the fuse holder back into the power entry
module. The power requirement of the instrument is easily changed by removing the fuse holder and
voltage selector which is the center portion of the power entry module. To remove, insert a screwdriver
into the right side of the fuse holder and pry out. Slide the voltage selector out, flip over and re-insert into
the fuse holder. Plug the fuse holder back into the power entry module.
Analog Needle Zero Adjust (S310 only)
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 the detector.
Connecting Detectors
Refer to the following drawing of the S310 rear panel. A 3 meter mini-DIN type cable with "D" shaped
connectors comes with Astral and Ultra calorimeters. A 3 meter BNC type cable comes with Vector
pyroelectric detectors. The input jacks on the rear panel of the S310 are labeled "Ultra", "Vector", and
"Astral" for hook up of these three types of detectors. Note: Only one detector should be plugged in at any
time. Note that the flat side of the DIN type cables should be oriented up when plugging in to the S310. Also
included with each detector is a 1/2" diameter mounting post for installing the detector to your working
surface. An optional mounting base, Scientech Model 301-019, is also available for holding the detector/post
assembly upright. Astral calorimeters are sensitive to all types of thermal input. Due to handling of the
calorimeter during setup and possible environmental temperature differences, thermal gradients may exist in
the calorimeter. Several minutes before usage may be required to allow the calorimeter to reach thermal
equilibrium. Note: When using a 25 mm Astral calororimeter for measuring average power levels below 30
mW and single pulse energy levels below 30 mJ, a Scientech Model 36-0203A, Isoperibol Enclosure, is
required. The isoperibol enclosure should not be used at average power levels above 30 mW, and single
pulse energy levels above 100 mJ because unwanted heat build up will occur.

Statistics Mode
The statistics mode will collect data on a pulse population of up to 1000 pulses. At your prompting, the
indicator 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. If you select AUTO range, the first few pulses of a run may be missed (not
counted) if the S310 has to internally change ranges. Therefore, if you want the first pulse to be counted, do
not select AUTO range. 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 press the STATS button. The number of pulses in the last run will appear in
the display. Use the RANGE (count up) and MODE (count down) buttons to change the display to the desired
number of pulses (up to 1000). Press the SELECT button to enter the pulse population to memory. Press the
SELECT button to begin the run. The indicator will automatically stop once the data has been collected.
Pressing the STATS button recalls the data to the display. The STATS button must be pressed for each event.
Once all of the data has been recalled, pressing the SELECT button starts a new run. Pressing the CANCEL
button returns the indicator to the mode of operation in effect prior to statistics mode.
External Trigger
The automatic trigger threshold of the S310 is 7 % of full scale. Energy values below 7% of full scale on any
range will not be displayed unless an external trigger is used. The external trigger input is located on the rear
panel of the S310. The external trigger pulse needs to have the following characteristics:
1. 2.5 volts min. to 5 volts max.
2. A minimum pulse width of 10 µsec. to a maximum of the laser pulse repetition rate.
3. A maximum rise/fall time of 500 nsec.
The trigger is generated on the rising edge of the incoming pulse.

Viable external triggers:
The following pulses will not trigger the S310:
A laser pulse must be delivered 1 to 3 msec. (depending on the detector type) after an external
trigger occurs or the meter will reset.
Pyroelectric Detector Operation With Oscilloscope
The pyroelectric detectors may be connected directly to a 1 MΩinput oscilloscope or a 50 ohm input if the
detectors are the HR type (PHF02, PHF05, PHF09, P05 or P09). The peak voltage of the detector divided by
the V/J or V/mJ output sensitivity = energy (joules or millijoules).
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.
Remove the two slotted 4-40 binder head screws located on the underside of the detector. Pull off the outer
housing to expose the battery. Remove the used battery from the battery holder and snap in the new battery.
Slide the outer housing back in to place and secure with the screws.
