light switches or double pole double throw (ON-OFF-ON)
switches, in each ON position you will need to alternate the
test leads between the switches terminals to determine which
two terminals control that ON position.

Heating Elements

Household appliances such as coffee makers and water
heaters contain heating elements which may require trou-
bleshooting. When making continuity checks on heating ele-
ments, disconnect the element(s) from the circuit(s) that sup-
ply it/them. Touch the test leads, one on each end of the ele-
ment and observe the display. The reading should indicate
low ohms. If the display doesn't change, the heating element
may be broken. If the element(s) show that continuity exists,
test for continuity of the circuit(s) that feed the element(s).
Thermostats
Make sure the thermostat control is in the OFF position. Remove
the thermostat cover. Touch the test leads to the contact points
on the thermostat. The display should read -0- ohms. If not,
either one of the contacts may be loose or broken.

BATTERY AND FUSE REPLACEMENT

1) Remove the screw in the back cover of the tester and
carefully separate the back cover from the front.
2) Note the polarity of the batteries when removing them
from their compartments and replace.
3) Use GB catalog number GF-0180 0.2A/ 250V replace-
ment fuses.
4) Carefully replace the back cover and tighten the screw. Do
not overtighten the screw as this may strip the threads in
the tester housing.
