pH calibration procedure

Sensors can be calibrated with 1 or 2 reference solutions (1-point or 2-point calibration). Standard
buffers are automatically recognized. Make sure that the correct buffer set is used (refer to
calibration options
on page 10).
1. Put the sensor in the first reference solution.
2. Wait for the sensor and solution temperature to equalize. This can take 30 minutes or more if the
temperature difference between the process and reference solution is significant.
3. Push the MENU key and select Sensor Setup, [Select Sensor], Calibrate.
4. Select the type of calibration:
Option
Description
2 point buffer
Use 2 buffers for calibration, for example pH 7 and pH 4 (recommended method). The
buffers must be from the buffer set that is specified in the Cal Options menu (refer to
Change calibration options
1 point buffer
Use 1 buffer for calibration, for example pH 7. The buffer must be from the buffer set that is
specified in the Cal Options menu.
2 point sample Use 2 samples or buffers of known pH value for calibration. Determine the pH value of
samples with a different instrument.
1 point sample Use 1 sample or buffer for calibration. Determine the pH value of samples with a different
instrument.
5. If the passcode is enabled in the security menu for the controller, enter the passcode.
6. Select the option for the output signal during calibration:
Option
Description
Active
The instrument sends the current measured output value during the calibration procedure.
