mVAC RMS CALIBRATION
1.
Set the analyzer rotary selector switch to mVAC.
2.
Connect a signal generator to the analyzer TEST and GND receptacles. The test
cable should include an internal two ohm load from input (TEST) to ground
(GND).
3.
With no signal applied (zero signal), adjust R80 for a reading of 00.0 on display.
Allow time for the reading to settle, it will take several seconds.
4.
Connect a precision digital voltmeter to monitor input and adjust signal generator
output for a 100 mVAC RMS sinusoidal 60 Hz. signal.
5.
Adjust R77 until the analyzer display matches the voltmeter reading.
OHMS CALIBRATION
1.
Set the analyzer rotary selector switch to OHMS.
2.
Connect a 100 ohm, ±0.1%, resistor to the analyzer TEST and GND receptacles.
3.
Adjust R82 until the display reads 100.0 ohms, or the actual value of the
connected resistor.
