3.1.4 Checking Before Use
This preliminary check function is possible only when the standard solution is set to
NIST, NIST2, USA, or China.
When the standard solution is set to CUSTOM, this function cannot be performed.
38
If you set the Checking Before Use setting to
ON, it allows you to check repeatability after
calibration by comparing the measured value of
pH7 standard solution with the calibration result.
After the set point calibrations are completed,
repeatability is automatically checked using the
deviation between the calibrated and measured
values at pH7.
For example, the sequence for the 2 points cali-
bration by pH7 and pH4 is as follows.
pH7 (Calibration of 1st point) --> pH4 (Calibra-
tion of 2nd point) --> pH7 (Repeatability check
with the calibrated value by 1st point)
