12.2. Advanced configuration
The previous chapter shows how to configure the calibration.
It is possible to go further and configure the whole device.
The goal of the configuration by QR code is generally to save time and limit
configuration errors when the air gage is changed often on the display.
Before sending a new configuration to the display, it is recommended to start sending
a reset command, so that all the previous parameters will be reset the default;
because the QR code we only modify the encoded parameters. Other parameters will
remain the same.
This command is : RST
After sending this command, you must start the configuration by the general
parameters, then configuration of the characteristics, and at the end sending the
calibration commands as described on the previous chapter.
12.3. Example of QR code configuration
The following example shows a complete configuration of the unit with QR code.
We use 2 air gages (1 plug and 1 ring) mounted on a plate, for pairing (diameter 20H7
and 20g6).
We must calculate and display the difference between the diameter 20H7 and the
diameter 20g6.
Air plug connected on C1:
Nominal :20mm
Upper tolerance : +0.021mm
Lower Tolerance : 0mm
Min master = 20mm
Max master = 20.0209
Air ring connected on C2 :
Nominal :20mm
Upper tolerance : -0.007 mm
Lower Tolerance : -0.020 mm
Min master = 19.9807mm
Max master = 19.9932mm
