Analog Output Trim
Current Output Trim (Io1 & Io2)
(Note: Can be trimmed to within .005 mA of nominal.)
To calibrate a current output (Io1 or Io2):
Set up the multimeter to read Amps, then connect it to the supply and return terminals of the
current output under test. Note that the loop must also be supplied with an external voltage.
Move the highlight to the port to be tested, press
Trim @ 4mA.
ENT
Press
. This triggers a 4.00 mA pop-up window. The multimeter should now be reading
4.00 mA.
If the multimeter reading does not match, use PC numeric keys or Magnetic Wand to enter the
multimeter reading.
Press
ENT
to register setting. This adjusts the meter's DAC (digital-to-analog converter) so that
a 4mA output corresponds with 4mA on the multimeter.
Re-check the multimeter to make sure that it is now reading 4mA.
Pgen Output Trim (Single Channel models only)
(Note: Can be trimmed to within 1.25 Hz of nominal.)
To calibrate a pulse rate output (Pgen1):
Connect a frequency counter to the supply and return terminals of the pulse rate output under
test.
Move the highlight to the port to be tested by pressing
move the cursor to Trim @ 1kHz.
ENT
Press
. This triggers a 1 kHz pop-up window. The frequency counter should now be reading
1 kHz.
If the frequency counter reading does not match, use PC numeric keys or Magnetic Wand to en-
ter the frequency counter reading.
ENT
Press
to register setting. This adjusts the meter's DAC (digital-to-analog converter) so
that a 1 kHz output corresponds with 1 kHz on the frequency counter.
Re-check the frequency counter to make sure that it is now reading 1 kHz.
