Once this indication is displayed, the meter will lock up. Change

the battery and restart.

CALIBRATION MODE MESSAGES

The date of the last calibration appears on the LCD each time the

calibration mode is entered. If calibration is performed for the

first time, “F.CAL” appears.

This indicates that the factory calibration is selected.

The flashing digits indicate that:

1) the month can be set

2) the day can be set

“Storage”: this prompt appears for 1 second at the end of the

calibration procedure, to indicate that the calibration data has

been stored.

“Error”: the concentration of the calibration solution used is not

correct. Repeat the calibration procedure with the right standard

solution, and verify it is not expired. If the calibration procedure fails

again, contact your dealer or the nearest Hanna Customer Service

Center.
