Press this key for at least 2 seconds for zeroing. This cancels electronic offset, detector
offset and ambient light on the detector. The TUNER should be zeroed before taking
measurements. Refer to p.11, adjusting the zero (steps 8 to 11).The TUNER will redo
the zero every time you press the zero button for two seconds, reboot the TUNER if you
wish to remove the zero cancellation.
3- Needle low-high / Att Control Key
This key enables memorization of the minimum and maximum readings. When enabled,
two blinking needles will continuously mark the current minimum and maximum values
since the memorization function has been enabled. (See point 6 and 7) for digital display
of minimum and maximum values). The minimum and maximum values for both the
needles and the digital high and low can be reset to the current measured value by
pressing this key 2 times quickly (like a mouse double click).
The blinking needles can be toggled on and off by pressing this key again, but once
activated, the minimum and maximum values are continuously updated, as long as the
TUNER is on.
When pressed for at least 2 seconds, Att is activated. Gentec-EO’s photodetectors are
calibrated with and without attenuator, with both responsitivity data captured in the
detector EEPROM and downloaded into the instrument upon start-up. This key allows
the user to select the proper configuration. The “ATT ON” LCD annunciator message
indicates whether the attenuator setting is activated. Press again for at least 2 seconds to
deactivate ATT, the message “ATT OFF” will scroll in the LCD to confirm button press
action.
4- Display / Needle style
Toggles the display between measurement, wavelength selection and range selection
modes. (See point 5 below for wavelength and range selection).
When pressed for at least 2 seconds, toggles the needle display between the following
four modes: single needle, tail needle (displays a short tail and a long tail following the
needle movement) and bar graph (displays a permanent, continuous trail between zero
and the current needle position).
5- Range ▲ / Range ▼ Control Keys
Allows the user to select the wavelength in wavelength display mode, or the range in
range display mode and in measurement mode. When selected by the user, the
wavelength and the range are automatically stored in non-volatile memory. The TUNER
returns to this same wavelength and/or range when it is turned on again with the same
detector head.
As the measured power varies upward, the range is automatically adjusted to provide the
most efficient reading There will be no automatic scale down as the power varies
downward.
The TUNER has 3 physical gains and it will always auto-scale the physical gain. The
TUNER will display a little variation during a physical gain change.
Range down can be manually selected using the range down button.
6 - Digital high Control Keys
Displays the maximum recorded values. To return to measurement display mode, press the key again.

1.4 Connectors Description
Fig. 1-2 TUNER Connectors
1- EXTERNAL POWER SUPPLY INPUT JACK.
Input voltage required: 9 VDC/100 mA. The external power supply does not charge the
batteries; it allows the use of the monitor without batteries, with dead batteries or simply
to avoid discharging the batteries inside the monitor.
CAUTION
Permanent damage to the optical meter may occur if an
external power supply other than the Gentec-EO P/N
200960A is used. Please call Gentec-EO or your local
distributor if extra power supplies are needed.
2- 0 to 1 VOLT ANALOG OUTPUT:
For monitoring laser average power by using external equipment such as a chart
recorder, a computer with an analog interface, a voltmeter, etc.
The output signal is the amplified power detector response, in fast or slow mode.
The 1 V value corresponds to the full scale reading of the selected range. That provides
the best signal-to-noise ratio. The measured power is then related to the output voltage
and to the selected range according to the following equations:

For example:
0.25 V corresponds to 2.5 Watts on the 10 W range
0.10 V corresponds to 30 milliwatts on the 300 mW range
Specifications:
Maximum output voltage: 1 V
Output impedance: 2.5 k
Connector type: Female 1/8” jack
3- PROBE INPUT JACK.
The TUNER uses a DB-15 female connector to mate with the detector heads (probes).
The TUNER works with all Gentec-EO thermal power detectors currently sold. It
automatically recognizes every power detector head, which ensures accurate auto-
calibration. More importantly, it can take advantage of our Personal wavelength
correction™. It reads the memory in the Smart Interface connector to provide a
wavelength correction that is based on spectral data measured from that specific
detector.
1.5 Display description
Fig. 1-3 TUNER LCD Display
The LCD provides measurement information, wavelength information, range information and other useful
messages.
The upper part of the screen displays TUNER setting information and digital values from the
measurements. The numeric display minimum resolution is 0.1% of the full scale. The smallest value
that can be displayed is 0.001 μW.
The lower part of the screen displays values from the measurements by showing a needle over an
analogue scale. The two following pictures show the needle in the “Tail” and “Bar Graph” display modes,
respectively.

Fig. 1-5 Needle Display in Bar Graph mode
When the batteries are discharged enough to compromise the measurement, the TUNER displays “LO
BATT” instead of the measurement. Refer to section 3 to replace the batteries.
If the voltage supplied by the external power supply is lower than 7 Volts, the TUNER displays “LO
JACK”.
If no detector head is connected when the TUNER is powered on, the message “No Detector” will be
displayed. Turn off the TUNER; connect the detector to the Probe Input Jack (see section 1.4) and turn
the TUNER on again.
If the detector is not recognized by the TUNER, the message “Bad Detector” will be displayed. Make sure
you use a detector head that is compatible with the TUNER (see section 1.2 for the list of compatible
detector heads).

2 Getting Started
This section contains important information concerning the installation and operation of the TUNER.
The TUNER is delivered ready to use. Just install the 4 AA batteries, insert a compatible detector
head in the Probe Input Jack (#3 in Figure 1-2) and press the I/O key.
2.1 Power measurement procedure
1- Install the power detector on its optical stand.
2- First, slide the connector latch to the right to unlock the connector.
3- Turn the TUNER off and connect a power detector head to the TUNER using the PROBE
INPUT JACK (see Fig. 1-2). It is recommended to turn the TUNER off before connecting a
new head in order to prevent any loss of information from the detector head’s EEPROM.
4- Slide the latch to the left to lock the connector into place.
5- Switch the TUNER ON using the I/O key. The TUNER displays the current wavelength for a
moment before displaying measurements. If this wavelength is not the wavelength of the laser,
go to step 6, otherwise proceed to step 8.
6- Select the proper wavelength using the Display control key to go to the wavelength display
mode, then the Range ▲ / Range ▼ control keys to select the wavelength.The TUNER
automatically stores the wavelength selection in non-volatile memory when the TUNER is set
back to the measurement display mode, so it returns to this same wavelength when it is turned
on again.
7- Return to the measurement mode by pressing the Display control key twice.
Adjusting the zero (steps 8 to 11)
8- Remove the detector’s protective cover.
9- Put the detector into the laser beam path. The entire laser beam must be within the sensor
aperture. Do not exceed maximum specified power densities. For the most accurate
measurement, spread the beam across 60% to 80% of the sensor area. Leave it there until the
detector has reached its equilibrium temperature.
10- Block off laser radiation to the detector.
The power read by the TUNER when no laser beam is incident on the detector may not be
exactly zero. This is because the detector is not thermally stabilized OR there was a heat
source in the detector’s field of view when you turned on the TUNER, OR the internal
electronic offset of the TUNER is not zero.
11- To reset the zero, wait until the reading has stabilized and press the Zero control key on the
front panel for at least 2 seconds. The TUNER will display “----“ for a moment and then return
to the normal measurement display. You are now ready to make an accurate measurement.
12- Apply the laser beam to the detector.
Notes:
•Refer to the specific power detector documentation for complete installation and operating
instructions.
•The power detectors are thermal sensors sensitive to temperature variations.
For high-precision measurements, it is recommended to:
•Allow the power detector’s temperature to stabilize before zeroing the TUNER.
•Do not touch the detector itself when handling the power detector. Touch only the stand.
•Avoid forced airflow or drafts around the detector.

3 BATTERIES
3.1 Battery selection
To avoid leakage and poor autonomy, it is highly recommended that only good quality, new and identical
alkaline batteries be put into the TUNER. Good quality rechargeable batteries can also be used with the
TUNER and recharged with an external charger.
The batteries need to be replaced if the TUNER displays “LO Batt” on its digital display or if it does not
power-up when the I/O control key is pressed.
3.2 Battery installation
- Put the TUNER face down on a flat surface.
- Lift the kickstand.
- Open and remove the battery door.
- Insert one battery in the nylon strap (to ease later removal) and insert it at one extremity of the TUNER
battery compartment with the right polarity. To avoid intermittent contact and involuntary disconnection,
firmly insert the batteries. Insert the other batteries over the nylon strap with the right polarity so that
pulling on the strap will pull every battery out of the TUNER.
- Put the battery door back in place.
3.3 Battery removal
- Put the TUNER face down on a flat surface.
- Lift the kickstand.
- Open and remove the battery door.
- Hold down the TUNER and slowly pull on the nylon strap to remove the batteries. Do not use a pointed
tool to remove the batteries, since that could puncture them. The batteries need a firm pull to be
removed.
