MAINTENANCE & TROUBLESHOOTING TIPS

Keep the pressure sensor(s) clean and protected from the elements 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 1-15 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 meter or immerse it in water.
