Section 3 

Operation 

 
This section describes how to set up and make measurements with your tester.  We recommend 
that you read the entire section carefully so that you can use all of the features of your tester. 
 

Setting up your Tester 

 
Your  tester  is  shipped  in  a  special  protective  container  that  should  prevent  damage  to  the 
instrument during shipping.  Check the shipping order against the contents of the container and 
report  any  damage  or  short  shipment  to  Compliance  West  USA.    The  container should include 
the following: 
 

 

The MegaPulse 1.2x50-16PF PV Tester 

 

Two large alligator clips with insulating boots (one red, one black) 

 

An 18 AWG Line Power Cord 

 

This Instruction Manual 

 

Calibration certificate with waveform calibration pictures 

 
If  reshipment  of  the  instrument  is  necessary,  please  use  the  original  shipping  container.    If  the 
original  shipping  container  is  not  available,  be  sure  that  adequate  protection  is  provided  to 
prevent damage during shipment.  We recommend that the instrument be surrounded by at least 
three inches of shock-absorbing material on all sides of the container. 
 
Remove the tester from its container and place it on a test bench.

  CAUTION: The MegaPulse tester 

is very heavy.  Two-person lift is required. 

 

AC Line Voltage Requirements 

 
AC line voltage requirements for your Tester are noted on the rear panel of the instrument.  Do 
not  connect  the  instrument  to  a  different  voltage  source.    The  cord  packaged  with  your 
MegaPulse Tester is for use in the United States.  If another power cord must be used, the cord 
must  be  rated  for  the  maximum  current  noted  on  the  rear  panel.    It  must  also  meet  the 
requirements  of  IEC  227  or  IEC  245,  and  mains  cords  that  are  certified  or  approved  by  any 
recognized national test house are regarded as meeting this requirement.
