1. SAFETY INFORMATION

SAFETY SYMBOLS

Warning! Dangerous Voltage (Risk of electric shock).
Caution! Refer to the user’s manual before using this Meter.

Double Insulation (Protection Class Ⅱ).

Alternating Current (AC).
Direct Current (DC).
Either DC or AC.

Ground (maximum permitted voltage between terminal and ground).

The symbol indicating separate collection for electrical and electronic

equipment.

The RESPONSIBLE BODY shall be made aware that, if the instrument

is used in a manner not specified by the manufacturer, the protection
provided by the instrument may be impaired.

The finger or any part of your body shall not be beyond the barrier of

the test probe when measuring.

Individual protective equipment must be used if HAZARDOUS LIVE

parts in the installation where measurement is to be carried out could
be ACCESSIBLE.

The following safety information must be observed to insure maximum personal
safety during the operation at this meter.
Do not operate the meter if the body of meter or the test leads appear to be
damaged.
Check the main function dial and ensure it is at the correct position before each
measurement.
When making current measurements ensure that the circuit is not “live”
before opening it in order to connect the test leads.
Do not perform resistance, diode and continuity test on a live power system.
Do not apply voltage between the test terminals and test terminal to ground
that exceeds the maximum limit record in this manual.
Exercise extreme caution when measuring live system with voltage greater
than 60V DC or 30V AC.

Change the battery when the “

” symbol appears to avoid incorrect data.

Use the DMM indoor, altitude up to 2000m and temperature 5℃ to 40℃.

Maximum relative humidity 80% for temperatures up to 31℃, decreasing
