MAINTENANCE TIPS
Keep your probes and thermocouples clean.
When the icon
appears in the left corner of the display, it’s time to replace the six
“AA” batteries that power the thermometer (although measurements will remain valid for
several hours after the low-battery indicator first appears). Replacing the batteries requires
removing the two screws that hold the battery compartment cover in place, as explained in
Step 1 of the setup procedure on page 6. After inserting fresh batteries in the correct
orientation, tighten the screws to secure the cover.
Remove the batteries when storing the thermometer for an extended period of time.
Do not drop or disassemble the thermometer or immerse it in water.

Optional accessories available from General Tools & Instruments include:
• Pt 100 ohm resistance-temperature detector (RTD) probes
• Types K, J, T, E, R and S thermocouple thermometers
