Digital Multi Meter F72
ENG
1. Introduction
This Meter is a handheld and battery operated Digital Multi Meter(DMM) with multi function.
This Meter is designed to meet IEC61010-1 & CAT III 600V over voltage category and
double insulation. The meter with holster that is giving the main body, though downsized,
high resistance against the shock of a drop. This operating instruction covers information
on safety and caution. Please read relevant information carefully and observe all the warn-
ings and note strictly.
The DMM as general measurement tool and widely used in the school, laboratory, factory
and other social field.
2. Safety note
Warning
To avoid possible electric shock or personal injury and to avoid possible damage to the
meter or to the equipment under test, adhere to the following rule:
■
Do not apply more than the rated voltage, of marked on the meter, between the input
terminal and grounding terminal.
■
Do not apply voltage between COM and OHM terminal, in the resistance measuring
state.
■
Do not measure current with test lead inserted into voltage or OHM terminal.
■
Do not expose the instrument to the direct sun light, extreme temperature and humidity
or dew full.
■
Inspect the test lead for damaged insulation or exposed metal.
■
Before measuring current, check the Meter's fuses and turn off power to the circuit
before connecting the meter to the circuit.
■
Disconnect circuit power and discharge all high voltag capacitors before testing
continuity, diode, resistance, capacitance or current.
