achieved at all times. The internal microprocessor will automatically
correct for any drift due to temperature or battery change.
The millivolts output function is identical to the volt function except
that the value is entered and displayed in millivolts.
Milliamps
To output Milliamps, press the MA key when the calibrator is in the
Output mode. The calibrator will prompt for the value desired.
Enter the desired current in milliamps and press ENT. If an improper or
out of range value is entered, the calibrator will display an error
message. Error messages and their meanings are listed on pages 57
and 58. If the value is within the operating limits, the calibrator will set
the output to the requested value. The output display will show the
actual output achieved at all times. The internal microprocessor will
automatically correct for any drift due to temperature or battery
charge.
If the calibrator cannot achieve current flow in the external loop, it will
display .000.
Once the loop is completed, the calibrator will begin displaying the
actual current value.
Frequency
To output a Frequency, press the FREQ key. The calibrator will prompt
for the output peak to peak (PP) amplitude.
