MAINTENANCE & TROUBLESHOOTING TIPS
Keep the light probe clean and its sensor under the protective cap when not in use.
When the icon appears in the left corner of the display, it’s time to replace the
six “AA” batteries that power the instrument (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 earlier. After inserting fresh batteries in the correct orientation,
tighten the screws to secure the cover.
If the meter “freezes” (like a computer) and buttons become unresponsive,
try resetting the instrument by pushing the RESET button on its right side
(callout 1-11 of Fig. 1) with the end of a paper clip.
Remove the batteries when storing this product for an extended period of time.
Do not drop or disassemble the instrument or immerse it in water.
