Appendix B

Recalibra on of the internal reference sensor

The appliance can have a complete or partial re-calibration yearly or when chosen by the user.
Calibration can be carried out directly on the keyboard of the appliance. The calibration is done by adjusting
the internal probe at one or more points of the range using a standard thermometer.
The calibration is possible only by setting the temperature unit "°C".
The purpose of re-calibration is to correct the error between the temperature indicated and the value of a
standard thermometer.
To calibrate the internal probe it is necessary to have a standard thermometer with a precision greater than
the calibrator to follow the instructions below:
1. Insert the standard thermometer probe in the most suitable hole of the calibrator.
2. Choose one or more calibration points (max 10 points) depending on the appliance range or the field
where one wishes to carry out the calibration.
3.
Set the first calibration point and wait for the calibrator to be stable (see the stability led)
4.
Enter the third menu level (see instructions) and select Pc.

5.
Use the or
the value. Confirmation is indicated by a beep.
6.
Repeat the step 3-4-5 for the other points.
At the end of the operation, wait for about 20 seconds to come back to the principal menu

RS232 communica on protocol

General characteristics:
9600
Baud Rate:
8
N. Bit:
The communication runs in half-duplex way which means that is transmission and reception could not be
contemporaneously present.
The regulator replies only after receiving command; it never replies itself.
The command and reply are ASCII character string, as detailed forward. The communication program will
be able to convert ASCII to decimal to extract numeric values. The default address is 1.
Baud rate: 2400, 4800, 9600 e 19200 baud, the Default value is 9600; the other parameters are standard.
