To calculate a voltage output:
1. Set up the multi-meter to read volts, then connect it to the supply and return terminals of
the voltage output under test.
2. Move the highlight to the port to be tested by pressing <Up/Down Arrow>, press <Right
Arrow>, then press <Down Arrow> to move the cursor to [Trim @ 2V].
3. Press <ENT>. This triggers a 2.00 Volts pop-up window. The multi-meter should now be
reading 2.00 Volts.
4. If the multi-meter
reading does not match, use the numeric keys to type in the multi-meter
reading.
5. Press <ENT> to register setting. This adjusts the meter’s DAC (digital-to-analog converter)
so that a 2.00 Volts output corresponds with 2.00 Volts on the multi-meter.
6. Re-check the multi-meter to make sure that it is now reading 2.00 Volts.
Pgen Output Trim
Note
Can be trimmed to within 1.25 Hz of nominal.
To calibrate a pulse rate output
1. Connect a frequency counter to the signal and reference terminals of the pulse rate output
under test.
2. Move the highlight to the port to be tested by pressing <Up/Down Arrow>, press <Right
Arrow>, then press <Down Arrow> to move the cursor to Trim @ 1kHz.
3. Press <ENT>. This triggers a 1 kHz pop-up window. The frequency counter should now be
reading 1 kHz.
4. If the frequency counter reading does not match, use the numeric keys to type in the
frequency counter reading.
