4.4. Other Settings and Saving the Startup Configuration
1. You can set the period over which to Average the measurements.
2. You can set the Energy Range to measure in. Select the lowest range
that is higher than the maximum expected energy measurement.
3. Set the Threshold to screen out noise that may be seen as false triggers
and measured as energy pulses.
4. If the sensor is a diffuser sensor, set diffuser to IN or OUT.
5. Select “Pulse Length” and choose the shortest pulse length setting that
is longer than your laser’s pulse length.
Warning:
Incorrect readings will result if pulse length is not set up correctly.
4.5. Energy or Average Power Measurement
Warning:
Do not exceed maximum sensor limits for power, energy, power density
and energy density as listed in tables 5 and 6 in section 9 of the manual.
Otherwise there is a risk of damaging the absorber.
With the pyroelectric sensor, you have been supplied a test slide with the
same coating as on your pyroelectric detector. You can also obtain this
slide from your dealer. You should use this slide to test the damage
threshold with your laser pulses. If the slide shows damage, then
either enlarge your beam or lower the laser energy until damage is no
longer seen.
4.6. To choose Energy or Average Power Measurement
In the main measurement screen press the Mode key. Select power or
Energy and press the OK key.

Getting Started
Note:
Any mention of the 843-R throughout this quick
reference refers to the 843-R-USB as well.
The 843-R is equipped with "soft keys." That is, the
functions of the keys change as indicated by the legend
above each key.
To connect sensor to the 843-R meter:
Insert the 15 pin D type connector of the measuring sensor
cable into the socket marked "Sensor Input" on the rear
panel of the 843-R meter.
To switch the 843-R on:
Briefly press the on/off switch (bottom-most key). The unit
will switch on, and the display will appear. Note that the
sensor must be plugged in before the unit is switched on.
The backlight for the 843-R’s LCD can be configured to
toggle between full, half, and low illumination. This toggling
will be performed by briefly pressing the on/off switch after
the 843-R has been switched on. To switch the 843-R off,
press the on/off switch and hold it for ~ 2 seconds until the
display blanks.
The 843-R automatically saves the current for next power
up.
Enter the Setup screen to update the following:
1. Select “Show Settings” and enter. Set to Yes to display
sensor settings in the measurement screens. Set to No
to hide the sensor settings and show a larger graph.
2. Select “Line Frequency” and enter. Set to 50Hz or 60Hz,
depending on the electrical power grid of the area that
you are in.
3. Select Date and enter. Scroll through and select Month,
Day, Year, Hour and Minutes with the Right arrow.
Change the selected item with the Down arrow.
