Caution:

1.Please read the manual carefully before using the meter.
2.The glass electrode at the bottom of the pen is fragile, please use it carefully after taking off the protection cap. Any damage may cause the invalid of the electrode.
3.The duration period of the glass electrode is one year from the date of purchase whether you use it or not, please change the electrode in time.
4.The electrode can not be used under the dry condition, always soak the electrode into the distilled water or purified water for10 – 30 minutes to activate before use.
5.The meter is ready to be used after the model shows on the screen.

Do not screw the probe cap at the bottom of the pH meter, pull it out directly!

Restore factory defaults:

(1) Press the "ON / OFF" key to start . (If it is switched on, you can omit this step)
(2) Hold down the "HOLD" key until the display shows the CLR symbol, then release the key And then re-calibration can be used

Temperature Measurement ℃ or ℉

The default temperature measurement is ℃. While the meter is off, press CAL and ON/OFF at the same time until the ‘℃’ or ‘℉’ appears on the LCD. Press HOLD to select the preferred unit and then press CAL to save. ‘SA’ will appear on the LCD for one second and then back to normal.

Automatic Temperature Compensation (ATC)

The product is capable of measuring the temperature and making compensation automatically, ‘ATC’ shows at the left corner of the screen.

Calibration:

The device is calibrating when "cal" flag at the lower right is flashing, don't put the device outside from the calibrating buffer.
(1). Prepare 4.01, 6.86 and 9.18 pH buffers, Use 6.86 pH buffer for the mid-range buffer first. The pH values for the buffers are given for 25 °C. If the sample temperature is not 25 °C, the pH values displayed for the buffers will reflect the correct pH value for the sample temperature. If the electrode is dry, submerge it in distilled water for 10 minutes before calibration. Ensure that the calibrating buffers are fresh.
(2). Press ON/OFF key to turn the meter on, submerge the probe in the buffer while stir gently. Then keep it still until a stable reading is reached. Press CAL for 3 seconds until the Text ‘CAL’ appears. Then release CAL, the meter will identify the current buffer value automatically, and display 6.86 in the LCD. The result will be saved while the text ‘SA’ displayed after 2 seconds. The meter will back to measuring mode after 1 second while text ‘End’ showed.
(3). If text ‘End’ is showed after press CAL, it means the calibration buffer is not fresh or the probe is aging. (4). Do not take out the probe from the buffer until text ‘End’ is showed in the LCD.
(5). Same steps as calibrating for pH 4.01 and 9.18.
