Voltage limit is the lesser of the DC+Peak AC and RMS values.
**
a. The supplied voltage must be less than 12V and greater than 4.4V, otherwise the probe
could be damaged or can’t operated properly.
b. Polarity is “+” inside and “-” outside. For wrong polarity, built-in circuit protects the
probe, no danger or damage will occur.
c. When the voltage of the cells become too low, the power indicator on the panel will
flicker.
