Calibration steps: The PH Meter Calibration steps: (1) Prepare 3 cups of pH: 4, 6.86, 9.18 calibration solution. (2) Put the pH meter into the first cup of calibration powder solution with a pH of 6.86, and press "CAL" to calibrate it to 6.86. Finally, rinse the PH electrode area with distilled water. (3) Put the pH meter into the cup of calibration powder solution with pH 4, and press "CAL" to calibrate it to 4.08. Rinse the PH electrode area with distilled water. (4) Put the pH meter into the cup of calibration powder solution with a pH of 9.18, and press "CAL" to calibrate it to 9.18. Finally, rinse the PH electrode area with distilled water. It will be calibrated successfully! The TDS Meter Calibration step: (1) Prepare a cup of 500 ppm water. (2)Press the "ON" button and insert the pen into the adjusted water. (3)Long press "shift" 5s to release, and then press "hold" key. (4)The TDS Meter will be calibrated to 500ppm. Package list: 1x TDS Meter 1x PH Meter 3x pH Buffer Powers Q&A Q: How to calibrate a pH meter? A: ph Meter had been calibrated by manufacturer in advance Q:does the TDS table need to be calibrated? A:no, it doesn't, the tds meter is calibrated automatically. Q:can it power off automatically? A:yes, and this function can save batteries Q:What do I need to pay attention to when using the instrument? A:Instrument is non waterpfoof, do not throw the instrument into the solution or make the solution over the immersion line, to avoid the circuit board short out.
