1.5 Front Panel Description

1 - Backlight / I/O Control Key

Switches the 1917-R on and off (press for at least 2 seconds to turn off the 1917-

R) and toggles backlight on and off when the 1917-R is on (backlighting is
available only when the 1917-R is powered by the external 9 VDC power supply).
Backlight status is memorized by the 1917-R.

If no detector head is connected when the 1917-R is powered on, the message “No

Detector” will be displayed. Turn off the 1917-R; connect the detector to the
Probe Input Jack (see section 1.4) and turn the 1917-R on again.

If the detector is not recognized by the 1917-R, the message “Bad Detector” will

be displayed. Make sure you use a detector head that is compatible with the 1917­R (see Table 1.2 for the list of compatible detector heads).

2 - Speed / Zero Control Key

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 1917-R will always power­up in fast mode.

10

Press this key for at least 2 seconds for zeroing. This cancels electronic offset,

detector offset and ambient light on the detector. The 1917-R should be zeroed
before taking measurements. Refer to p.13, adjusting the zero (steps 6 to 8). The
1917-R will redo the zero every time you press the zero button for two seconds,
reboot the 1917-R 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 val ues s ince the me moriz atio n 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 1917-R is on.

When pressed for at least 2 seconds, Att is activated. Newport’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 Control Key

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 single

needle, tail needle (displays a short tail following the needle movement) and bar
graph (displays a permanent, continuous trail between zero and the current needle
position).

5 - Range

▲ Up and Down ▼ 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
1917-R 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 1917-R has 3 physical gains and it will always auto-scale the physical gain.

The 1917-R 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.

7 - 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 Digital­Low control key. The Uno 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.

1- PROBE INPUT JACK:

The 1917-R uses a DB-15 female connector to mate with the detectors. See

section 2.1 for compatible detector list.

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:

 outputVPower

selected Range ofMax

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 3.5mm mono jack

3- 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 System Operation

This section contains important information concerning the installation and
operation of the 1917-R hand-held power meter. The 1917-R is delivered
ready to use. Just insert a detector in the Probe Input Jack (#2 in Figure 1-2))
and press the I/O key.

2.1 Making a Power Measurement

1- Install the power detector on its optical stand.

With the 1917-R turned off, connect the power detector head to the 1917-R using the

2-

PROBE INPUT JACK (see Fig. 1-2). It is recommended to turn the 1917-R off

before connecting a new detector head in order to prevent any loss of information from
the detector head’s EEPROM.

13

3-

Fasten the DB-15 thumbscrews.

Switch the 1917-R ON using the I/O key. The 1917-R displays the firmware version

4-

and then the current wavelength for a moment before displaying measurements. If this
wavelength is not the wavelength of the laser, go to step 5, otherwise proceed to step 6.

5-

Select the proper wavelength using Display button until you obtain the wavelength

display mode (
1917-R automatically stores the wavelength selection in non-volatile memory when the
1917-R is set back to the measurement display mode, so it returns to this same
wavelength when it is turned on again.

Zero Offset Adjustment (steps 6 to 8)

Remove the detector’s protective cover.

6-

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.

Block off laser radiation to the detector.

7-

The power read by the 1917-R 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 1917-R, OR it is
caused by the internal electronic offset of the 1917-R.

λ) and then, press the ▲ up and Down ▼ down control keys. The

14

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

the front panel for at least 2 seconds. The 1917-R will display “Zero“ for a moment
and then return to the normal measurement mode. You are now ready to make an
accurate measurement. Pressing the

Zero key again will not undo the zero; it will re-

do it.

9-

When you select ATT for at least 2 seconds, you must enter a wavelength using

Display button and then ▲ up and Down ▼ down control keys to select λ. To save

λ and get back to measure reading, press Display and release until you get back to

the

measure state.

Apply the laser beam to the detector. The laser must operate in CW mode for

10-

measurements with low power detectors.

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 1917-R.

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

• Avoid forced airflow or air drafts around the detector.

Fig. 1-5 1917-R Needle display in Bar Graph mode

When the batteries are discharged enough to compromise the measurement, the 1917-R 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 1917-R displays
“LO JACK”.

If no detector head is connected when the 1917-R is powered on, the message “No Detector” will
be displayed. Turn off the 1917-R; connect the detector to the Probe Input Jack (see section 1.4)
and turn the 1917-R on again.

If the detector is not recognized by the 1917-R, the message “Bad Detector” will be displayed.
Make sure you use a detector head that is compatible with the 1917-R (see section 1.2 for the list
of compatible detector heads).

The following error messages can also be displayed:

no detector: 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: the detector is not supported or 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 key or the Slow key when this feature is unavailable
on the detector.

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