4) OPERATION

CAUTION: Before and after hazardous voltage measurements, test the voltage

function on a known source such as line voltage to determine proper meter functioning.

DC Voltage and AC Voltage functions

Inputs are made through the test lead terminals.

Note: DC 400.0mV range is designed with 1000M high input impedance for least

current drain in measuring small signals, and can cope better with most commercially

available voltage output transducers/adapters. The non-zero display reading is normal

when the meter inputs are open circuit, which will not affect actual measurement

accuracy. The meter will show a close to zero reading when the inputs are shorted.

Open input is actually a floating condition, which is not a zero-volt-input condition.

Note: AC 400.0mV range selection is by RANGE button manually, and is specified from

AC 40mV & up for Model 161s and from AC 60mV & up for True RMS Model 162s.
