 Use the Meter only as specified in this manual or the 

 

       protection by the Meter might be impaired.

 

  

 

  

Always use proper terminals, switch position, and 

 

       range for measurements.

 

 

  

 Never attempt a voltage measurement with the test 

 

       lead inserted into the A input terminal.

 

 

  

 Verify the Meter’s operation by measuring a known 

 

       voltage. If in doubt, have the Meter serviced.

 

 

  

 Do not apply more than the rated voltage, as  marked  

 

       on Meter, between terminals or between any terminal 

 

       and earth ground.

 

 

  

 Do not attempt a current measurement when the open

 

       voltage is above the fuse protection rating. Suspected

 

       open circuit voltage can be checked with voltage fun-

 

       ction.

 

 

  

 Only replace the blown fuse with the proper rating as

 

       specified in this manual.

 

 

  

 Use caution with voltages above 30 Vac rms, 42 Vac 

 

       peak , or 60 Vdc. These voltages pose a shock hazard.

 

 

  

 To avoid false readings that can lead to electric shock

 

       and injury, replace battery as soon as low battery indi-

 

       cator 

 appears.

 

 

  

 Disconnect circuit power and discharge all high-voltage 

       capacitors before testing resistance, continuity, diodes, 

 

       or capacitance.

 

 

  

 Do not use Meter around explosive gas or vapor

 

 

  

To reduce the risk of fire or electric shock do not ex-

 

       pose this product to rain or moisture.
