Notes: • When the instrument is not calibrated or calibration is cleared

(default values loaded) there is no “expired calibration”,

and the display always shows the “CAL” “INTV” tags blinking.

• When an abnormal condition in the RTC is detected, the

instrument forces the “expired calibration” status.

pH CALIBRATION DATA

Calibration data is stored automatically after a successful calibration.

To view the pH calibration data, press GLP while in measurement mode.

The instruments will display the time (hh:mm) of the last calibration.

Use the ARROW keys to scroll through the calibration data:

• The date (yyyy.mm.dd).

• The pH calibration offset.

• The pH calibration slope (the GLP slope is the average of the calibration

slopes; the percentage is referred to the ideal value of 59.16 mV/pH).

• The pH calibration buffers in calibrating order and with the selected

resolutions at calibration moment.

The first pH calibration buffer:

The second pH calibration buffer:

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 51 52
