Read First: Safety Information 

To ensure that the tester is used safely, follow these instructions: 

 

Do not use the DMM if the tester or test leads appear damaged or if you suspect that the 

DMM is not operating properly. 

 

Disconnect the live test lead before disconnecting the common test lead. 

 

When using the test leads, keep your fingers behind the finger guards on the test leads. 

 

Do not apply more than 600V rms between a DMM terminal and earth ground.

 

 

Disconnect the test leads from the object circuit before measuring the voltage. The DMM 

enters scan mode automatically. Then connect the test leads to the voltage. Do not connect 

the test leads to the circuit first and then switch it on before the circuit is powered

If so, the 

DMM will go to the resistance measure function first when it’s powered, and it’s easy to be 

damaged or operated incorrectly when the power is suddenly switched on.   

 

Use caution when working with voltages above 60V dc or 30V AC rms. Such voltages pose a 

shock hazard. 

 

The user is cautioned that failure to use this equipment in accordance with the manufacturer’s 

instruction  may  be  detrimental  to  the  operation  of  this  equipment  and  may  impair  any
