How to Perform Measurement
Voltage Measurement
Voltmeter connector’s inner shield is internally connected to Guard or Common as
shown in Figure 3-6. The internal connection must be made properly. It must be
connected to Guard for the guarded voltage measurement. And it must be
connected to Common for the unguarded voltage measurement. Incorrect setup
causes measurement errors. See “Guarded and Unguarded Connections” on
page 98 for more information.
