DC Voltage Calibration
On the UUT select DC V, 2V range, and connect the calibrator HI volts output to the V-Ω terminal and the
calibrator LO volts output to the COM terminal. For each step in Table 8, select the listed range, program
the calibrator for the corresponding UUT input, and make the specified adjustment or check.
