Users Manual

Measuring Voltage

The Meter is capable of measuring up to 1000 V dc, 750 V ac (8845A) or 1000 V ac
(8846A).
To avoid blowing the current fuses and possible damage to
other equipment, do not apply voltage to the meter's input until
the test leads are properly connected to the input, and the
proper voltage function selected.

Measuring DC Voltage

To make a dc voltage measurement:
1. Press E.
2. Connect the test leads to the Meter's inputs as shown in Figure 4-1.
3. Connect the test leads to the circuit and read the measured voltage in the Meter's
Figure 4-1. Input Connections for Voltage, Resistance, and Frequency Measurements
