Voltage Check at Battery
1)
Remove cover from the controller and remove the
DC battery.
2)
Insert black and red test leads into COM and the proper
V terminal (1.5Vdc and 9Vdc depending on the type
of battery).
3)
Place selector switch into the 1.5V or 9V battery
test position.
4)
Touch one probe to the metal lead on each side of
the battery.
5)
Check the reading on your multimeter.
•
A good 1.5Vdc battery will read above 80.0mA.
•
A good 9Vdc battery will read above 22.0mA.
6)
Replace the battery.
CAUTION:
Avoid electrical shock or instrument damage
by not exceeding 10Vdc while in battery test mode.
Acceptable battery test range:
Varies by battery type
and manufacturer. A negative value only indicates that the
(+) probe is on the (-) terminal. In most cases a good 1.5V
battery will read above 80.0 mA, while a good 9V battery
will read above 22.0 mA.
