Repeatability check
To confirm the measurement accuracy in the Ion measurement, the repeatability check is
available.
1. After the calibration, press F4 (REPEATABILITY) in CAL screen.
2. Immerse the electrode in the standard solution calibrated by the first point, and
press the CAL key.
The difference between the calibrated value and measured value is displayed.
When the repeatability check is successfully completed, the electrode status “OK”
appears on the screen.
