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.
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-Fuse Holder 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 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 fuse holder door.
5. Replace the fuse with a new one of the correct rating.
6. Replace the fuse holder door and power inlet cord.
