4.1.2 Checking Before Use

Tap on the right of the Checking Before Use

item to set the preliminary checking.

2. Tap .

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)

1 2 ... 58 59 60 61 62 63 64 65 66 67 68 ... 113 114
