1. Introduction

This Meter is designed to meet IEC61010-1 & CAT III 600V over voltage
category . 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.
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 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 voltage capacitors

before testing continuity, diode, resistance, capacitance or current.
