Fig. 1-1 UNO Front Panel

2.3 Front Panel Description

1- control key.

UNO on and off.

2- Zero / dBm control key.

Cancels electronic offset, detector offset and ambient light on the detector. This key

should be pressed before taking measurements. Refer to p.7 adjusting the zero (steps 8
and 9). The hidden dBm function is available by pressing more than 2 seconds on the
Zero control key.The Uno will convert the displayed number in dBm (dB referenced to
1mW) and will display “dBm” unit. To get back to the previous display in Watt, press again
more than 2 seconds on the Zero control key.

3- Att control key.

Photodetectors can be calibrated with and without attenuator. This key allows the user to

select the proper configuration and wavelength. The ATT LCD annunciate indicates
whether the attenuator sensitivity is activated.

4- Save λ control key.

After selecting the proper wavelength using the λ up and λ down control keys, pressing

the Save λ control key stores the wavelength in non-volatile memory and returns to the
measurements with the corresponding sensitivity.

5- λ up and λ down control keys.

Allows the user to select the appropriate wavelength.

6- Fast and Slow control keys.

These keys are only useful with thermal detector heads. The fast mode enables
anticipation, which shortens the natural response time of the detector. The slow mode
disables anticipation. By default, the monitor is in Fast mode. This setting is not stored
in non-volatile memory and therefore returns to Fast mode on every power-up.

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.

Fig. 1-2 UNO Connectors

2.4 Connector Description

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.

2- PROBE INPUT JACK.

The UNO uses a DB-15 female connector to mate with the detector heads (probes).

The UNO works with all Gentec-EO 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.

3 Getting Started

4

This section contains important information concerning the installation and operation of the UNO. The
UNO is delivered ready to use. Just install the 4 AA batteries, insert a detector head in the Probe
Input Jack (#2 in Figure 1-2) and press the I/O key.

4.1 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 UNO off and connect a power detector head to the UNO using the PROBE INPUT

JACK (see Fig. 1-2). It is recommended to turn the UNO off before connecting a new head in
order to prevent any loss of information from the detector head’s EEPROM.

UNO User’s Manual Revision – 6.1 8

4- Slide the latch to the left to lock the connector into place.
5- Switch the UNO ON using the I/O key. The UNO 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 7.

6- Select the proper wavelength using the λ up and λ down control keys. Then press the Save λ

control key to store the wavelength in non-volatile memory and return to the measurement
mode.

Adjusting the zero (steps 7 to 11)

7- Remove the detector’s protective cover.

Put the detector into the laser beam path. The entire laser beam must be within the sensor
aperture. Do not exceed maximum specified densities, energies or powers. 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.

8- Block off laser radiation to the detector.

The power read by the UNO 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 UNO, OR from the internal
electronic offset of the UNO.

9- To reset the zero, wait until the reading has stabilized and press the Zero button on the front

panel. The UNO will display “ZEro“ for a moment and then return to the normal measurement.
You are now ready to make an accurate measurement. Pressing the Zero button again will
not undo the zero; it will re-do it.

10- When you select ATT you must enter a wavelength and then press Save λ to exit.

11- Apply the laser beam to the detector. The laser must be CW for photodetectors.

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 UNO.

• Do not touch the detector itself when handling the power detector. Touch only the stand.

• Avoid forced airflow or drafts around the detector.

4.2 Display description

Fig. 1-3 UNO LCD Display

The LCD provides measurement information, wavelength information, attenuator selection and other
useful messages.

When the batteries are discharged enough to compromise the measurement, the UNO displays “LO”
instead of the measurement. Refer to the battery maintenance section to replace the batteries.

The ATT field indicates if the detector sensitivity used takes into account the presence of the attenuator
that the detector was calibrated with.

Error messages can also be displayed:

E-05 indicates that no detector is present on power-up.

E-07 appears after pressing the ATT control key with a detector that does not have attenuator
calibration. The message disappears a few seconds after pressing the control key.

E-08 indicates that the detector is not supported or that the detector calibration EEPROM is
corrupted. It can also appear if the DB15 is poorly secured or is worn out.

E-09 appears after pressing the FAST or SLOW control key with a detector that does not have
anticipation (photodetectors). The message disappears a few seconds after pressing the control
key.

Any other error message indicates a malfunction and should be reported.

6.1 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 UNO. Good quality rechargeable batteries can also be used with the
UNO and recharged with an external charger.

The batteries need to be replaced if the UNO displays “LO” on its digital display or if it does not power -up
when the I/O control key is pressed.

6.2 Battery installation

- Put the UNO face down on a flat surface.

- Lift the kickstand.

- Open and remove the battery door.

- Insert one battery in the nylon strap (to ease removal) and insert it at one extremity of the UNO 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 UNO.

- Put the battery door back in place.

6.3 Battery removal

- Put the UNO face down on a flat surface.

- Lift the kickstand.

- Open and remove the battery door.

- Hold down the UNO 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
in order to have a reliable contact.
