Calibration Setup
1. Connections
Ensure that the Model 9100 is connected to the Standards DMM as shown in Fig. 10.4.6.1 or 10.4.6.2
(depending on the current being calibrated), and that both instruments are powered on and warmed up. If the
measuring instrument has a switchable signal guarding facility it should be switched to remote guard. If it
does not have a guard facility, there can be no guard lead to the DMM.
2. 9100
a. Ensure that the 9100 is in STANDARD CAL mode and then select the AC Current function by pressing
the 'A' key on the right of the front panel, followed by pressing the '
A' screen key adjacent to the display.
b. Ensure that Sinusoidal waveshape is selected, and that the Phase facility is deselected (
