3.5 Determining Battery-wear Judg-
ment Values
For determining battery wear, first measure internal resis-
tance in a new or good battery, and then set values for judg-
ing battery wear.
Ex.: When values measured for a new battery are 0.428 mΩ and
2.008 V, set the internal resistance caution value at 0.6 mΩ (1.5 times
the initial value) and the internal resistance warning value at 0.8 m
Ω
(2 times the initial value) and set the voltage caution value at 1.8 V
(90% of the initial value).
1.
Referring to "Section 3.1 Pre-operation Inspection" (⇒
p.35), configure the range and conduct the zero-adjust
operation.
2.
Connect the test lead to a new or good battery.
3.
Read the measurement values.
