System Calibration

3.4.4 Control System Calibration by AK-protocol command

We can start and stop SYSCAL over serial interface by AK-protocol commands. Therefore the commands SCAL, STBY and ASTZ has to be used.

Start-Command: SCAL Kx m (n)

K0

else: switch into normal mode

= TEST ZERO-GAS

K1...999

timeout in sec

4

= TEST SPAN-GAS1

K1...999

timeout in sec

5

= TEST SPAN-GAS2

K1...999

timeout in sec

6

= TEST SPAN-GAS3

K1...999

timeout in sec

7

= TEST SPAN-GAS4

K1...999

timeout in sec

If optional parameter n is not in command string the appropriate variable is not changed.

Starting condition: All attached AMs are in the Standby-Mode (AK STBY) and the variable CALSTAT is 0, otherwise the response is BUSY (BS).

Stop-Command: STBY K0

Only using K0 will stop running SYSCAL-procedure (besides all the procedures of the other AMs).

Check-Command: ASTZ K0

The ASTZ K0 command gives the information if a SYSCAL-procedure is running or not.

If running it returns a „SCAL“ if not this string is missed.
