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 meter on sliding the switch on the top.
Immerse into solution up to the max immersion level.
Stir gently and wait until the display stabilizes.
After use, switch off PH meter, use the water clean the electrode and replace protctive cap.
DO NOT USE DISTILLD 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.
Calibration is now complete.
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 meter cannot b switched on or the display fades, pull out the battery compartment and replace all four 1.5V batteries, while paying attention to their polarity.Batteries should only be replaced in a safe area using the battery type specified in this instruction manual.
