Set Measurement Range

Battery resistance or Strap resistance only has manual ranges. The default range for
battery resistance or Strap resistance measurement is 30 mΩ. You can push
cycle through different ranges in this sequence: 30 mΩ > 300 mΩ > 3000 mΩ > 3 mΩ.
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.
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:

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
