Use Z
LOW
to test a battery’s health
Aside from reading a battery’s voltage level using the DC
voltage measurement function, you can also use the Z
LOW
function to test a battery’s health.
If you detect that the measured battery’s voltage shown in
the Z
LOW
function is declining gradually, this means that the
capacity of the battery- under- test is not enough to support
regular functions. Use this simple and quick test to
determine if a battery has enough voltage capacity to
support regular activities.
NOTE
During Z
LOW
measurements, autoranging is disabled and the multimeter’s
range is set to 1000 V in the manual ranging mode. The analog bar graph
represents the AC+DC voltage value combined.
NOTE
Prolonged used of the Z
LOW
function will consume the capacity of the
battery-under-test.
