General Tools and Instruments WK2017SD - Manual (Page 18)

MAINTENANCE & TROUBLESHOOTING TIPS
Keep all probes and electrodes clean and protected from the elements when not in use.
When a pH electrode is not being used, General recommends keeping its head inserted in
the bottle of pH buffer solution.
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, 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.
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 instrument or immerse it in water.
