Safety

The following safety information must be observed to insure maximum 
personal safety during the operation of this meter: 

•  Do not use the meter if the meter or test leads look damaged, or if you 

suspect that the meter is not operating properly

•  Never ground yourself when taking electrical measurements. Do not 

touch exposed metal pipes, outlets, fixtures, or anything which might be 

a grounding potential

•  Keep your body from grounding by wearing dry clothing,  using rubber 

shoes, rubber mats, or any other approved insulating material

•  Ensure that you isolate the circuit and that there is no electrical current 

running through it before you cut, unsolder, or break it. Small amounts 

of current can be dangerous

•  Use caution when working above 60V DC or 30V AC RMS. Such volt

-

ages are a shock hazard

•  When using the probes, keep your fingers behind the finger guards
•  Measuring voltage which exceeds the limits of the Multimeter may 

 

damage the meter and expose the operator dangerous currents of  

electricity. Always recognize the meter’s voltage limits as stated on the 

front of the meter.
