Pipe Tracing using a Sonde: Batteries
Duct Sonde
The Duct Sonde is supplied at 33kHz only (yellow casing)
and is powered by a single AAA (LR03) size alkaline battery.
1. To turn the Duct Sonde on, use a large flat bladed
screwdriver to unscrew the battery cover located within
the hollow end of the Sonde casing. Insert a new battery
into the battery compartment with the positive end down.
2. Replace the battery cover fully using the screwdriver to
secure. The Duct Sonde is now transmitting a signal.
3. To turn the Sonde off the battery must be removed.
NOTE Only use alkaline batteries. Dispose of the used battery safely in accordance with local regulations.
NOTE Always use a new battery in a Sonde if you expect to take a long time to trace the pipe or duct route.
WARNING The Locator frequency MUST always be set to the same frequency as the Sonde.
