Amps

When  the  test  is  first 
selected  the  message 
“PLUG  In  HI”  will  be 
briefly 

displayed 

to 

remind  the  user  that  the  High  range 
Amps  probe  should  be  plugged  into 
the Amps socket. Pressing the button 
will cycle you through DC Amps, AC 
Amps,  and  AC  Peak  to  Peak  Amps.  
The  bargraph  is  a  easy  way  to  see 
trends in amps being measured.

The  DC  Amps  function  can  measure 
up to +/- 600 Amps.  The AC functions 
use  a  certified  true  RMS  chip  to 
provide accurate interpretations of AC 
waveforms.  The Peak to Peak function 
(not shown) is the best measurement 
tool to determine the amplitude of the 
signal.

Note:  AC auto ranging takes more time to occur than DC auto 
ranging. This is to allow the AC peak and rms circuits to settle 
after the abrupt change in scaling.
