Section 2 

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 GF-30AC-T Tester 

 

A 10 AWG Test Return Lead 

 

An 18 AWG Line Power Cord  

 

A 14 AWG Test Power Cord 

 

A plastic calibration screwdriver 

 

An alligator clip/wire assembly 

 

This Instruction Manual 

 
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  one  inch  of  shock-absorbing 
material on all sides of the container. 
Remove the Tester from its container and place it on a test bench.   

 

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. 

 

Fuse Replacement 

 

There is a user-replaceable fuse (F1) located on the rear panel of the instrument.  It is located behind a 
door in the Power Inlet-Power Switch-Fuseholder device.  The fuse rating is noted on the rear panel.  Do 
not attempt to replace it with a fuse of any other rating. 
 
Use the following procedure to replace the fuse F1: 
1.  Turn the power switch to the O or off position. 
2.  Unplug the instrument from the source of supply. 
3.  Remove the power inlet cord from the instrument. 
4.  Using a small screwdriver, pry open the fuseholder door. 
5.  Replace the fuse with a new one of the correct rating. 
6.  Replace the fuseholder door and power inlet cord.
