Calibration interval
80
The calibration interval determines the time interval between
regular system calibrations.
The terminal reminds you to calibrate regularly by the
flashing probe symbol on the display.
The calibration interval is set to 7 days in the factory. You
can change the interval (1-999 days).
For most applications, we recommend a shorter calibration
interval.
