OPERATION
•Remove the protective cap. Do not be alarmed if white crystals
appear around the cap. This is normal with pH electrodes and
they dissolve when rinsed with water.
•Turn the tester ON by pressing the 'ON/OFF' button.
•Immerse into solution up to the max immersion level.
•Stir gently and wait until the display stabilizes.
•After use, Turn the tester off by pressing the 'ON/OFF' button,
use the water clean the electrode and replace the protective cap.
Do not use distilled or deionized water for storage purposes.
•Large fluctuations in readings could be due to lack of calibration,
dry electrode or rundown batteries.
CALIBRATION
•Immerse the tester up to the maximum immersion level in pH 6.86 buffer solution.
•Allow the reading to stabilize and using a small screwdriver adjust the calibration trimmer to read 6.86
•Immerse the electrode in PH4.01 or PH9.18 the standard buffer solution of borax. Until the display
shows '3.96-4.06PH'or'9.13-9.23PH' Always use fresh buffers for calibration.
Important The instrument must be re-calibrated whenever.
•The electrode or battery has been replaced.
•Approximately one mouth has passed from the last calibration.
•The electrode has been used in particularly taxing conditions.
•The utmost accuracy is required.
BATTERY REPLACEMENT
When the battery symbol -----appears on the display, this indicates a low battery and only 1 hour
of continuous use remain. though the unit may continue to function ,the accuracy of the unit will be
affected beyond the 1 hour.twist open the battery compartment lid. remove old batteries and replace
with fresh ones noting polarity as show in battery compartment.
ELECTRODE REPLACEMENT
1.Remove the protective cap.
2.Unscrew the plastic ring on the top of the electrode .
3.Pull out the electrode and replace it with a new one. make sure the gaskets are in place before screwing
back the ring.
