* Voltage limit is the lesser of the DC+Peak AC and RMS values.
**
a. 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.
b. 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.
c. When the voltage of the cells becomes too low, the power indicator on the
panel will change colour and then switch off.
