Fresh batteries will always show three
bars.
When the indicator shows two bars, the
voltage of the batteries has started to
drop. When there is a single (blinking)
bar left, you should replace the batteries.
The meter will turn off automatically
when the battery voltage drops too low.
This indicator is shown next to the
battery charge indicator if there is a
measurement problem. The most likely
causes are low battery and probe
problems, for example:
- Battery voltage too low to power the
probe. The measured values may
show asterisks "*" instead of
numbers.
- Probe has been disconnected
- Probe has been damaged
- Probe is incompatible
- Probe is wet (probe recovers
automatically when it dries). The
measured values may show asterisks
"*" instead of numbers.
