Measure Strap resistance in sequence mode
A strap string is created right behind battery string automatically in the same profile. The
strap number equals to battery number. Push the
Strap
softkey to switch to strap string
test. The display shows
to indicate strap string. Push
Battery
softkey to switch back
to battery string test.
Set Measurement Range
Battery resistance or Strap resistance only has manual ranges. The default range for
battery resistance or Strap resistance measurement is 30 m
Ω
. You can push
to
cycle through different ranges in this sequence: 30 m
Ω
> 300 m
Ω
> 3000 m
Ω
> 3 m
Ω
.
The battery voltage measurement is in auto ranging mode, and the range cannot be
changed.
Save Battery Test Readings
In Meter mode, push the
Save
softkey to save the current resistance, voltage and time.
All saved data is stored in chronological order. In Sequence mode, push the
Save
softkey to save the current resistance and voltage readings. The current serial number
increases by 1. The test progress bar moves to the right by one cell.
Note
If the test lead does not connect to battery or the test lead is not
installed, the Save function is invalid.
Erase Test Readings
To erase the test readings for a certain battery in Sequence mode:
1. Use
and
to point the cursors to the cell that corresponds to the correct battery.
2. Push
the
Erase
softkey.
The pointed cell becomes empty. Push the
Save
softkey to save new test readings
for this battery.
Activate Low-Pass Filter for Resistance Measurement
Excessive high level of ac ripple voltage can have a negative impact on the battery
resistance measurement. Use the built-in low pass filter to stabilize or reduce the impact
of ac ripple on resistance measurements.
To activate the low-pass filter for battery resistance measurement, in Meter mode, push
LO
softkey, in Sequence mode, push the
More
softkey and push
LO
softkey. The
display shows the
LO
icon.
