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.
