TP display If you use a temperature sensor, a flashing TP display indicates that the
difference in temperature of the standard solutions is too high (more
than 2 °C).
Displaying the
calibration data
You can view the data of the last calibration on the display. The pro-
ceeding is described on page 48.
Printing the
calibration protocol
The calibration protocol contains the calibration data of the current cal-
ibration. You can transmit the calibration protocol to a printer via the se-
rial interface (see page 51).
Note
You can automatically print a calibration protocol after the calibration.
To do so, connect a printer to the interface according to section 4.7.2
before calibrating. After a valid calibration, the record is printed.
Sample printout:
Calibration evaluation After the calibration, the measuring instrument evaluates the calibra-
tion. The slope (in mV) is evaluated. The probe symbol shows the cal-
ibration evaluation.
