Operating Instructions:

• Remove the protective cap.

• Turn on the meter.

• Immerse the electrode in the solution to be tested.

• Stir gently and wait for the reading to stabilize.

   

• Press the "℃/"F" key,choice the C/F for measuring.

• Press the "TDS/pH"button,choice the PH or TDS for measuring.

• After use,turn off the meter.Rinse the electrode with distilled water to minimize contamination.

• Always replace the protective cap after use.

Note:

TDS meter value is the reading ×10.

Example:the reading display to 128,actual TDS meter value for:128X10=1280ppm

Calibration:

1)PH

• Rinse the ph electrode first with distilled water,and suck it with filter paper(not included).

• Turn on the meter.Press the"TDS/pH"button,choice the PH for measuring.

• lmmerse the ph electrode in pH 6.86(Or pH7.00)buffer solution,gently shake the meter and wait for a stable display.

• Regulate the trimmer with the screwdriver provided until display shows"6.86"("7.00")at buffer solution temperature of 25℃.

• Rinse the ph electrode with distilled water,and suck it with filter paper(not included)

• lmmerse the pH electrode in pH4.01 or pH9.18(pH10.0) buffer solution,gently shake the electrode and waiting for the reading to stabilize.The showing value and buffer solution's ph value is within error range.

• The calibration of the instrument's pH range is now complete.

Important:

1. The ph meter should be recalibrated under following situations:

2. The meter has been used for long time since the last calibration or use.

3. The meter has been used in particularly continual conditions.

4. The utmost accuracy is required.

2)TDS

1. Turn on the meter.Press the"TDS/pH"button,choice theTDS for measuring.

1. Immerse the electrode in the distilled water.Activate it about five minutes.

2. Immerse the electroder in 1382 ppm calibration solution.And stir it gently.

3. Unscrew the battery compartment cap on the top of the meter.

4. Allow the reading to stabilize and with a small screwdriverturn the calibration trimmer until the display shows“141(141x10=1410)

5. Rinse the electrode with distilled water and suck it with filter paper.

6. Immerse the electroder in 150ppm calibration solution.gently shake it and wait for a stabledisplay.The showing value and buffer solution's value is within error range.

7. Rinse the electrode with distilled water and suck it with filter paper.

8. The calibration of the instrument's TDS range is now complete.

Note: this item comes without retail box and battery,thanks!
