OPERATION

1. Remove the protective cap. Connect pH electrode and temperature electrode.
2. Clean the electrode with distilled water, and dry it well.
3. Connect the power adaptor to turn on.
4. Put the pH electrode, temperature electrode, and TDS electrode into the testing solution. Stir lightly and take a few seconds for a stable reading.
5. Press the “ “key to choose the CAL/t °C/°F. Press” “for 5 seconds to calibrate the MODE TDS ( EC) value. Press the “ “key to choose different value display of “TDS/EC/ SALT/S.G. Press ” ” for 5 seconds to CAL calibrate the pH value.
6. Turn off the meter after use. Clean the electrode in distilled water. Put on a protective cap.

PH CALIBRATION

1. Pour standard buffer solution pH6.86, pH4.00 and pH9.18 (at 25°C) separately into three different clean beakers.
2. For accurate calibration, fill one buffer solution into two beakers. One is for cleaning the electrode, and the other one is for calibration. By doing so, the pollution level can be reduced to the least.
3. Connect to the power adaptor to turn it on.
4. Immerse the pH electrode into standard buffer solution pH6.86, then stir gently until the value is stable. Long press the “   key for about 5 seconds. When the screen displays”  “meter go into the pH6.8614.9 automatic correction mode (the meter can automatically identify standard buffer solution of pH4.01. pH9.18 and pH6.86). Display value corresponds to the standard buffer solution, the calibration is finished.
5. Clean the pH electrode. Immerse the pH electrode into standard buffer solution pH4.01, then stir gently until the value is stable. Long press the ”  “key for 5 seconds. When CAL the screen displays” meters go into the pH4.01 automatic correction mode. The display value corresponds to the standard buffer solution, the calibration is finished.
6. Clean the pH electrode. Immerse the pH electrode into standard buffer solution pH9.18, then stir gently until the value is stable. Long press the” “key for 5 seconds. When CAL the screen displays” “meter goes into the pH9.18 automatic calibration mode. The display value corresponds to the standard buffer solution, the calibration is finished.

EC CALIBRATION

1. Turn on the meter. Press the”  “key to choose the EC-ms.
2. Immerse the electrode into the distilled water. Activate it about five minutes.
3. Immerse the electrode into EC calibration solution 12.88ms/cm (at 25°C), and stir it gently.
4. When the reading is stable, long press the ” “key about 5 seconds. When CAL/+ the screen display” “or” “. Press the” ” or” “, until the display CAL/+ shows “12.80-12.90”
5. Clean the electrode with distilled water and dry it with filter paper.
6. Immerse the electrode into EC calibration solution 1.413ms/cm(at 25°C), and stir it gently. The display value is the same as the value of the calibration solution or approaching the value.
7. Clean the electrode with distilled water and dry it with filter paper.

NOTICE
The electrode must be recalibrated: No calibration for a long time. Regular and long-term continual use. High accuracy is required.
