CONDITION

The display is provided with a 5-dot bargraph (unless the feature is disabled)
which gives an indication of the electrode status after calibration as follows:

Bargraph indication

Condition value

All 5 dots steady

81 to 100% of life

4 dots steady

61 to 80%

3 dots steady

41 to 60%

2 dots steady

21 to 40%

1 dot steady

1 to 20%

1 dot blinking

0%

Only frame is ON

No info available

The “condition” bargraph remains active until the end of the calibration day.

Note:

The electrode condition is evaluated only if current calibration includes
at least two.

CLEAN ELECTRODE

Each time pH calibration is performed, the instrument internally compares the
new calibration with the one previously stored.

When this comparison indicates a significant difference, the “CLEAN” “ ” tags
blink on the LCD to advise the user that the pH electrode may need to be cleaned
(see ELECTRODE CONDITIONING & MAINTENANCE section for details, page 41).
After cleaning, perform a new calibration.

Note:

If the calibration data are cleared, the comparison is done with the
default values.
