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)

(type of SYSCAL)

(channel

number)

(optional parameter)

0 = ZERO-CAL K0 n = 1: switch into test mode

1 = ZERO/SPAN-CAL K0

2 = PROGRAM K0 else: switch into normal mode

3 = 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.
