Battery Replacement
1. Twist off the battery compartment cap.
2. Hold the battery housing in place with one fi nger. Remove the battery
carrier by pulling on the small tabs.
3. Replace the four CR2032 batteries.
Observe polarity.
4. Replace the battery compartment cap.
NOTE: If the batteries are removed, stored data and user calibrations will
be cleared. A new user calibration will be required. Factory calibrations
will be retained.
Cleaning and Conditioning the Electrode
The TRACER will arrive in a factory-cleaned condition and is ready to be
used. A separate preconditioning method is not required.
Surface Cleaning – Only in case of visible surface contamination or if readings
should become erratic, use a disposable laboratory towel wetted with ethanol
or isopropyl alcohol and gently rub the surface, until no more residue is
visible.
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, among other factors. 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.
5. Tighten the electrode collar fi rmly enough to make a good seal. A rubber
gasket will seal the electrode with the meter.
