Calibration

One-point calibration (only 6.86 point calibration, the accuracy is ±0.1PH)
Dissolve the 6.86 buffer powder in 250 ml of distilled water.
Turn the meter on by pressing the “ON/OFF” button, and immerse the electrode into the PH6.86 solution, gently stir and wait for 5 minutes.
Press the “Cal” button to see the display number until the number is 5 and release the button then. To find the 6.86 calibration point display will start flashing 6.86 and wait until the display stops flashing. Then the one-point calibration finished.
Two-point calibration ( the 4.00 and 9.18 point calibration, the accuracy is:±002PH)
00 point calibration： Dissolve 4.00 buffer powder in 250ml of distilled water, and immerse the electrode into PH 4.00 solution Press the “CAL” button to see displaying number is 5 and then release, display starts to flash 6.86, then press and release immediately the second time, reading will start to flash 4.00, and wait until the display stops flashing.
18-point calibration: Dissolve 9.18 buffer powder in 250ml of distilled water, immerse the electrode into PH 9.18 solution, Press the “CAL” button to see displaying number going to 5 then release, Display will start flashing 6.86, then press and release immediately the third time, reading will start to flash 9.18 and wait until the display stops flashing.
