Operation Preparation Insert the adapter into the 220V AC power supply; after that, insert the dc output plug into "DC9V" socket. Screw off the short circuit plug of the meter, Screw on the pH electrode. Please keep clean and dry of electrode before using, avoid to be polluted. Switch on the instrument and preheat for 5 minutes.

Maintenance and note Notes for Testing Sample The electrode plug and socket of instrument must keep clean and dry, short circuit plug should be put on when not using, for preventing the intrusion of dust and moisture. The different sample should use the suitable pH electrode(for example: measure strong acid、strong alkali or pure water and so on.

When using liquid chargeable electrode, please note that if liquid inside decreases to be less than half volume, please use burette to add liquid from hole at the top. When measuring, please turn the blue circle to cover the small hole.
