Instrument Calibration

1.          Soak the electrode in 7.0pH/4.0pH solution. If the display does not show the right pH value, adjust the unit to the right measurement. (Remove the protection cap and adjust the knob. Right knob for 7.0pH / Left knob for 4.0pH).

2.          Clean the electrode with distilled water.

3.          Soak the electrode into buffer solution at 4.0pH. If the display does not show the right pH value then adjust the left point to make it displays 4.0pH.

4.          If it is necessary please repeat procedure 1. to 3.

Maintenance

l          If the instrument has not been operating for a long time, it should be recalibrated before use.

l          Usually clean the electrode with distilled water after use.

l          Replace the batteries when the display became dim.

Operating

1.          Remove the protection cap and turn on the power.

2.          Place the electrode in sample solution until the result show on the display.

3.          Turn off the power, clean the electrode and cover the protection cap after test.
