Gain Calibration Adjustment Overview
The ADC and zero calibration adjustment procedure must have been recently performed before beginning
gain calibration. Gain calibrations can be made using either the front or rear input (not available on the
34460A) terminals. On the 34461A/65A/70A, make sure the Front/Rear switch matches the terminals in
use.
Never turn off the instrument during a gain or flatness calibration. This may cause calibration memory for the
present function to be lost.
Valid Gain and Flatness Calibration Input Values
Gain calibration can be accomplished using the following input values.
Function
100 mV to 100 V
DC Volts
100 µA to 1 A
DC Current
Ohms (2W and 4W) 100 Ω to 100 MΩ
Frequency
100 µA to 1 A
[1]
AC Current (rms)
100 mV to 10 V
[1]
AC Volts (rms)
[1]
Valid frequencies are nominal frequencies ±1%.
