Option

Description

Offset limit

Sets the maximum mV value that is accepted for the offset. Options: 1 to
250 mV (default: 25 mV). The offset value is the difference between the
expected and the measured mV value for the standard solution.

Reminder

Sets a time interval for probe calibration. A reminder shows on the meter after
the time interval. Options: Off (default), 1 day, 7 days or 30 days. The meter
can also make a sound during the reminder (Settings > Sound).
