1.
Measure no load voltage Uo:
a. Switch off load resistors of lead battery tester.
b. Apply test probes with correct polarity to terminals (+ and -) of battery (38, 39).
c. Read off no load voltage Uo value displayed on lead battery tester.
NOTE
l
if no load voltage Uo < 12.5 V, charge battery with charger vi J3
slave receptacle 24 V Connector.
l
if the battery gets very hot during charging, It is defective and must
be replaced.
l
When no load voltage Uo > 12.5 V, measure load voltage UB.
2. Measure load voltage UB:
a. On the lead battery tester, activate the number of load resistors required for the particular type
of battery.
b. Apply test probes with correct polarity to terminals (+ and -) of battery (38, 39).
c. Read off load voltage UB value displayed on lead battery tester.
NOTE
l
if load voltage UB > 10.0 V, battery is at least 40% charged, and its
high current load capability is sufficient for starting.
l
if load voltage UB < 10.0 V, charge battery with charger via J3 slave
receptacle 24 Connector.
