1. Introduction

    This Meter is a handheld and battery operated Digital
    Multi Meter(DMM) with multi function. This Meter is
    designed to meet IEC-61010-1 CAT III 1000V over 
    voltage category and double insulation. The entire 
    outer surface of the case has been formed with thermo
    plastic elastomer,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 warnings and note strictly. The 
    DMM as general measurement tool and widely used in
    the school, laboratory, factory etcsocial field.

2. Safety Note

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:

Warning

• 

Do not apply more than the rated voltage of marked

  on the meter 

• 

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.
