4. DETAILED OPERATING INSTRUCTIONS
G.
PUSH START BUTTON
The audible alarm stops. The voltmeter displays the battery
voltage, the ammeter reads 0 and the timer starts. “OP” on the
timer illuminates and the red LED flashes.
H.
SET DISCHARGE CURRENT
Slowly turn the multi-turn Ampere Adjust knob
clockwise to the desired discharge current. The
ammeter displays the current as it is being
adjusted.
4.7 TEST COMPLETION AND ANALYSIS
The Beta D-50 automatically completes the test with the set parameters. It may
however be required to measure the individual cell voltages for nickel-cadmium
batteries during the test (see section 4.7.2).
I.
WAIT FOR THE DISCHARGE TEST TO AUTOMATICALLY
COMPLETE
During the test the battery voltage, discharge current, and elapsed discharge
times 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 4.7.1 and
4.7.2 for respective battery type.
