1. Safety information

The meter is a handheld and battery operated Digital AC Clamp

Meter with multi function. This clamp meter has been designed to

meet IEC1010-1 and CAT III over Voltage category.

Warning

To avoid possible electric shock or personal injury and possible damage

to the meter or the equipment under test, you are must be adhere to the

following rules.

1-1. Safety cautions

● User must be read the operating instructions thoroughly and

between

the “INPUT” terminal and “COM” terminal.

● Do not expose the instrument to direct su

nlight, extreme

temperature and moisture

or dew full.

● You always are careful when working with voltage above
60V DC or 30V AC rms.

● Keep fingers behind the clamp barrier while measuring
current..
