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.

TUNER User’s Manual Revision 4.2

Gentec Electro

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

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).

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.

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:

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

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).

TUNER User’s Manual Revision 4.2

Gentec Electro

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.

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)

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  detect

or’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

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.
