switch on the top.
-Stir gently and wait until the
display stabilizes. Readings are
automatically compensated for
temperature variations.
-After use, switch off the pH
meter, clean the electrode and put
the cap back on.
NOTE: Do not use distilled or
deionized water for storage
purposes.
Large fluctuations in readings
could be due to a lack calibration,
electrode dryness or low battery.

maximum immersion level in pH
6.86 buffer solution.
-Allow the readings to stabilize
and use the included screwdriver
to adjust the calibration nut at the

NOTE: Always use fresh buffers
for calibration purposes.
