Front Panel Description

Backlight / On-Off

Switches the TUNER on and off (press for at least 2 seconds to turn off the TUNER) and toggles backlight on and off when the TUNER is on (backlighting is available only when the TUNER is powered by the external 9 VDC power supply). Backlight status is memorized by the TUNER. 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).

Speed / Zero] Press and release this key to toggle between fast and slow modes. The fast mode enables anticipation, which shortens the natural response time of the detector. The slow mode disables anticipation. By default, the TUNER will always power up in fast mode. 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.

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.

Display / Needle style
This is a dual purpose button. When pressed quickly it provides three functions wavelength selection, range selection, and back to measurement in that order. When pressed and held for at least 2 seconds it toggles between the four modes of needle display: single needle, short trailing tail, long trailing tail and bar graph (displays a permanent, continuous trail between zero and the current needle position). For more instruction on wavelength setting and correction, or range selection please see 5 below.

Range ▲ / Range ▼ Control Keys
When in the wavelength setting mode, it allows the user to read the present wavelength setting and/or to adjust it by pushing and holding the up or down keys until getting the desired wavelength. Once the “Display /Needle Style” button is pushed again, this wavelength will saved in non-volatile memory until the next time it is changed. When in the range setting mode, it allows the user to select the appropriate power range by pushing and releasing the up or down keys. Push the “Display/Needle Style” again and you’ll go back to the power measurement mode. 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.

Digital high Control Keys
Displays the maximum recorded values. To return to measurement display mode, press the key again.

Digital low / W/dBm Control Keys
Displays the maximum recorded values. To return to measurement display mode, press the key again. The dBm function is available by pressing more than 2 seconds on the Digital-Low control key. The Tuner will convert the displayed number in dBm (dB referenced to 1mW) and will display “dBm” message unit and then no units. To get back to the previous display in Watt, press again more than 2 seconds on the Zero control key. The ranges are also displayed in dBm.

Display
Two parts digital/analog display LCD screen. Refer to section 1.5 for a detailed description.

Connectors Description

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.

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:

• PowerVoutputMax of Range selected

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

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 autocalibration. 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.

Display description

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.

Needle Display in Tail mode

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).

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.

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.

BATTERIES

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.

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.

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.

Damaged battery
If the batteries get damaged and/or leak, please dispose them according to your country’s battery recycling regulations before sending the product back .
