Basic connections to DUT
Unguarded connections
Basic unguarded connections are shown in Figure 2-3, the DUT is the voltage, current, resis-
tance or charge to be measured. Circuit high is connected to the center conductor of the input
connector and circuit low is connected to the inner shell of the connector. For unguarded volts
and ohms measurements, the driven guard (GRD) must be off.
NOTE:
For Volts and Ohms,
GRD must be off.
