2.3.2
Setting the Measurement Parameters
1.
Set
Range
to the appropriate manual range,
AUTO
, or
dBm
(logarithmic scale). Note that
when selecting a manual range, the correct range is the lowest one that is larger than the
expected maximum power of the laser.
2.
Set
Laser
to the appropriate laser setting. If the wavelength you want is not among the
wavelengths listed, select one and press the arrow key that is next to it to open the
Modify
screen. Using the up/down Navigation keys to change each number and the right/left keys to
move to the next number, key in the wavelength you want. When finished, press the
Enter
key.
3.
Set
Filter
to
IN
or
OUT
as physically configured on the sensor. Not necessary for sensors with
built-in filter state detection.
4.
Set
Average
to the period you wish to average power over or set to
NONE
to disable.

Pyroelectric or Photodiode Energy Sensors
2.4.1
Using 1919-R with Energy Sensors
1.
Plug in the Pyroelectric/Photodiode energy sensor. 1919-R will reconfigure itself to work with
the attached sensor.
2.
All of the sensor’s measurement parameters are shown on the main screen. Use the
Navigation keys to select and change the parameters.
3.
Use the Navigation keys to select the parameter to change and press the
Enter
key. Change
the setting with the Navigation keys. Press the
Enter
key to save.
4.
1919-R saves the changes automatically for next startup of the instrument.
Warning:
Do not exceed maximum sensor limits for power, energy, power density, and energy
. Otherwise, there is a risk of damaging the absorber.
