Model 72-7228: OPERATING MANUAL
the input terminals of the Meter and turn the Meter power off.
Ensure the rotary switch is in the correct position prior to measurement.
To prevent damage to the meter, range or mode changes should not be
made during measurement.
Do not perform measurements when the Meter’s back case and battery
compartment are not closed to avoid electric shock.
Do not input higher than 600V between the two Meter’s input terminal to
avoid electric shock and damage to the meter, do not input higher than
600V between the Meter’s two input terminals.
When working with effective voltages over 70VDC or 33VAC RMS,
special care should be taken for there is danger of electric shock.
Use the proper terminals, function, and range for your measurements.
Do not use or store the Meter in an environment of high temperature,
humidity, explosive, inflammable and strong magnetic field. The performance
of the Meter may deteriorate after dampened.
When using the test leads, keep your fingers behind the finger guards.
To avoid electric shock, do not touch the bare wires, connectors, unused
input terminals or the circuit under testing during measurement.
Disconnect circuit power and discharge all high-voltage capacitors before
testing resistance,
continuity and diode.
