Note
The battery voltage measurement is in auto ranging mode, and the
range cannot be changed.
Caution
In this function, the voltage between the positive and negative
poles of a battery must be < 60 V. A voltage >60 V exceeds the
rating of the fuse in the Product and causes an open circuit.
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.
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, push the LO softkey.
The display shows the LO icon.
