8845A/8846A Users Manual Measuring Voltage The Meter is capable of measuring up to 1000 V dc, 750 V ac (8845A) or 1000 V ac (8846A). WCaution 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. The dc voltage icon | will appear to the right of the displayed value as shown below. -0.001698V F1 F2 F3 F4 F5 caw021.eps 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 display.
