POWER OPTIONS
The Teledyne Test Tools Rogowski probes can be powered by an external DC source or by battery.
External Supply
The Teledyne Test Tools Rogowski probes can be powered by an external DC supply. The DC
voltage must be 12V(±10%) using a centre positive connector. When the DC supply is present
a RED indicating LED adjacent to the socket is illuminated.
Standard Alkaline Batteries
Four fully charged AA alkaline batteries provide approx. 25 hours operation. Healthy batteries
are indicated by the GREEN LED. If the LED is RED the batteries are depleted and must be
