4.3 Checking Before Use

When the preliminary check function is ON, you can check repeatability with the standard
solution of the 1st point calibration. Use this function to check measurement accuracy by
checking repeatability.
An operation guide is displayed after the 2nd point calibration is completed. Check the
repeatability according to the operation guide.
After the set point calibrations are completed, repeatability is automatically checked using
the deviation between the calibrated and measured values at the 1st point.
