Calibration Setup
1. Connections
Ensure that the 9100 is connected to the Standards DMM as shown in Fig. 10.4.5.1 or Fig. 10.4.5.2 (depending
on the magnitude of 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. Model 9100
Ensure that the 9100 is in STANDARD CAL mode and then select the DC Current function by pressing the
'
A
' key on the right of the front panel.
