Two, operating procedures

1, take off the protective sleeve

2, first with distilled water to clean the electrode, and the filter will be attached to the electrode and the surrounding water dry.

3, touch the "key", namely open power.

4, the instrument is inserted into the test solution, so that the measured electrode is immersed in the solution.

5, gently shaking the instrument, to be stable after reading the display number, read the value below the screen as the temperature of the solution.

6, the use is finished, press "open key", turn off the power supply, clean the electrode with clear water, cover the protective sleeve.

Three, calibration

1, the amount of 6.86, 4 and 9.18 standard buffer solutions were poured into different clean beaker.

2, for accurate calibration, of every kind of buffer solution, with two beakers in repacking, a beaker for the electrode was rinsed, another beaker used to calibrate. In this way, the pollution degree of the standard buffer solution can be reduced to the minimum.

3, a "switch" button, the opening of power supply.

4, the electrode into the PH6.86 standard buffer solution, and gently shake, to be displayed stable.

5, long press the "correction" button (in 6.86 solution), about five seconds, the instrument into the automatic calibration status (instrument power) automatic recognition and PH6.86 standard PH4.00 buffer, until the display value and standard buffer solution at temperatures where the pH value. Complete PH6.86 point correction.

6, cleaning electrode, and by filter will be attached in the electrode and the surrounding water drain into the PH4.00 standard buffer solution, and gently shake, to be show the value of stability.

7, long press the "correction" key (in the 4 solution), with the operation step 5, that is, complete the PH4.00 point correction

8, cleaning electrode, and by filter will be attached in the electrode and the surrounding water drain electrodes into the PH9.18 standard buffer solution, and gently shake, to be show the value of stability, the display value in the range of allowable error.

9, so the calibration of the instrument is completed.

Note: in the following cases, the instrument must be re calibrated.

1, the instrument has been used or placed after a long time;

2, the use of electrodes is particularly frequent;

3, the measurement accuracy is particularly high;

Usually do not press the "calibration key" otherwise the instrument need to re

Four, battery replacement

If the display value is fuzzy or not, then check the battery voltage, less than 3V should be replaced in a timely manner.

When replacing the batteries, unscrew the battery cover can be replaced, pay attention to the battery polarity. (after replacing the battery, need to be re calibrated)
