„ Replacing the Electrode
The TRACER is shipped with an electrode attached. Electrode life is limited and
is dependant on the frequency of use and care. If the electrode needs to be
replaced, follow these steps for removing and connecting electrodes.
1. Turn meter off.
2. To remove the electrode, turn the collar counter-clockwise and remove it.
3. Gently rock the electrode from side to side, pulling it downwards, until it
disconnects from the meter.
4. To attach an electrode, carefully plug the electrode into the meter socket.
Note that the electrode connector is keyed to ensure a proper connection.
CAUTION: Take case to align pins carefully. Bent or broken ins will cause the
meter to malfunction.
5. Tighten the electrode collar firmly enough to make a good seal. A rubber
gasket will seal the electrode with the meter.
