Using VZ
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 VZ
LOW
function to test a battery’s health.
If you detect that the measured battery’s voltage shown in
the VZ
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.
