How to use
Before first use, ensure the electrode is stored in the supplied storage solution and perform a calibration according to the calibration function instructions. Power the meter with the specified 3 V battery and switch on to allow the display to stabilise. Rinse the electrode with distilled or tap water, immerse the rod electrode into the sample to an appropriate depth and wait for the reading to stabilise. Use the HOLD function to capture the displayed pH and temperature values if needed. After measurement, rinse the electrode and return it to the storage container with the supplied solution to prevent drying out.
Usage recommendations
Perform regular calibration checks and clean the electrode after each use. Store the device and electrode in the supplied container with storage solution when not in use. Avoid prolonged immersion beyond the recommended depth and protect the instrument from strong impacts or excessive humidity beyond splash conditions.
