**
1.
The supplied voltage must be less than 12 V and greater than 4.4 V, otherwise
the probe could be damaged or might not operate properly.
2.
Polarity is “+” inside and “−” outside. If the polarity is wrong, a built-in
circuit protects the probe so that no danger or damage will occur.
3.
When the voltage of the cells becomes too low, the power indicator on the
panel will flicker.
