This    innovative    

AutoCheck

  feature    automatically    selects 

 Hz

measurement function  of 

ACV

,

 DCV

, or  

Resistance  ()

  based  on 

the input via test leads.

CAUTION : 

Before and after hazardous voltage measurements, test 

the  voltage  function  on  a  known  source  such  as  line  voltage  to 
determine proper meter functioning.

OPERATION

TM

AutoCheck  mode

  With no input, the meter displays “Auto” when it is ready.

  With  no  voltage  signal  but  a  resistance below 10M (nominal) is 

    present,   the   meter   displays  the  resistance  value.  When   the 
    resistance is below the “Audible Threshold”, the meter further gives
    a continuity beep tone.

  When a signal above the voltage threshold of 1.5V DC or AC up to

    the rated 1000V is present, the meter displays the voltage value in 
    appropriate DCV or ACV, whichever larger in peak magnitude.
