    Voltage limit is the lesser of the DC+Peak AC and RMS values 1000Vrms and + 1400V(DC + Peak AC) @1/100 & 1/1000
* a. The supplied voltage must be less than 12V and greater than 4.4V, otherwise the probe could be damaged or can¡¦t be operated properly.
b. polarity is "+" inside and "¡V" 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. Additional Accessories - Shown Below
