HIPOT TESTING
Introduction
4.
If still no voltage, the ground is disconnected and
you must have the outlet repaired or find a
grounded outlet.
120
volt mowers should be hipot tested to assure a
safe product after any electrical repairs are performed.
Hipot Tester Safety Rules
Safety Rule #1
•
Turn the voltage to the lowest setting (if applicable)
and the power switch to OFF when not using the
tester. This will prevent inadvertently energizing
the test probes.
Safety Rule #2
•
Do not touch the product when the tester is
connected to the product. This goes for anyone
else in the area. Hipot testing is a one-person job.
Extra hands increase the likelihood of a shock.

Testing Procedure
Safety Rule #3
Hipot testing can be done quickly and safely using the
following FIVE simple steps.
•
Do not test any product that is wet or snow
covered. You will almost certainly get an incorrect
reading. Worse yet, the moisture could act as a
conductor and you could get a shock.
Step #1: Check the Hipot Tester
Set the tester and the lowest value and touch the two
probes together (Figure 59). The tester should signal a
failure (audible or visual or both depending on tester
used).
Safety Rule #4
•
Do not rest the product to be tested on a metal
bench. If you contact the bench, you could receive
a shock.
If the tester does not signal a failure, the tester requires
repair.
Safety Rule #5
•
Always test to make sure the electrical outlet is
properly grounded before plugging in the hipot
tester.
Testing the Outlet for Ground
1.
Set a voltmeter on the AC volt scale to read 110
VAC.
2.
Place one probe in the round (ground) and the
other in one of the two flat terminals. The
voltmeter should read 110 VAC (Figure 58).

3.
If there is no reading, move the probe to the other
flat terminals.
