* Voltage limit is the lesser of the DC + Peak AC and RMS values.**
a. The supplied voltage must be less than 16V and greater than 3.3V, otherwise the probe could be damagedor will not operate properly.
b. For wrong polarity of power sources, a built-in curcuit will protect the probe and no danger or damage will occur.
c. When the voltage of the cells become too low, the power indicator on the panel will change its color then distinguish.
