to the desired level.
G.
PUSH START BUTTON
The audible alarm stops. The voltmeter displays the battery
voltage, the ammeter reads 0 and the timer starts. The red
LED on the timer illuminates. “OP” on the timer illuminates
and the red LED flashes.

Slowly turn the multi-turn Ampere Adjust knob clockwise to
the desired discharge current. The ammeter displays the
current as it is being adjusted.
I.
WAIT FOR THE DISCHARGE TEST TO
AUTOMATICALLY COMPLETE
During the test the battery voltage, discharge current, and
elapsed discharge time are displayed. The voltage will
continuously decrease while the current remains constant. The
test completes when either the set discharge time or the low
cutoff voltage has been reached. An audible alarm sounds and
the displays freeze at their final values.
J.
1. IF TEST PASSED
The green Accept lamp illuminates. This indicates the discharge
has continued through the duration of the set discharge time (the
red LED and “OP” on timer is off.) without the cutoff voltage being
reached. The battery is usually fit for service, after complete
recharge. See below under respective battery type.
