pH Calibration & Measurement
1. Rinse the pH electrode with clean water and blot using lint-free tissue to remove exc ess water.
Perform 2-point calibration using pH 7 and 4 for acidic sample or pH 7 and 10 for alkaline sample.
Perform 3-point calibration using pH 7, 4, and 10 if you are unsure of the expected sample value. It is recommended to calibrate with pH 7 first.
3. Press CAL button on the meter to switch to calibration mode.
The screen will display the set pH buffer group briefly and the will start blinking until the reading stabilizes.
Press
4. Press ENT button to conrm the pH reading. To abort calibration, press MEAS key.
The meter will switch to measurement mode and the electrode icon will appear on the screen.
Press
5. Repeat step nos. 1 to 4 to perform calibration with the next pH buffer(s).
The meter allows up to 5 calibration points for USA / NIST pH buffers and up to 6 calibration points for DIN pH buffers.
