pH Calibration
This meter has been manufactured for use with a pH electrode that
generates 0mV at pH7.00 (177.4mV at pH4). If your pH electrode does not
meet stated specications or is being used for the rst time, calibration
procedures are necessary. Calibration also ensures accurate
measurements. It is always recommended to carry out a two point
calibration for better accuracy.
Required Equipment for Calibration
1. pH Electrode (See Accessories and Replacement Parts)
2. pH Buffer Solutions (See Accessories and Replacement Parts)
Calibration Procedure
1. Prepare buffer solutions for calibration. It is recommended to start
with calibration buffer pH 7.00 pH, followed by either pH 4.00 or

2. Connect the optional pH electrode into the pH input jack
3. Turn the meter on by pressing the POWER button.
