6.4 Commands for serial interface
All interface commands are preceded by a colon and the carriage return (CR) complete.Command
and parameters must be separated by a space. By appending a question mark at the respective
command can otherwise be read to changing parameters. Receptions commands are
acknowledged with „OK“, and missing or incorrect commands with „ERROR“.
Command
Answer function
Auto mode
:saaz <0 | 1>
Auto zero before each cycle (phase 4)
0 --> off
1 --> on
:acy <1 ... 100>
Cycles to be carried out
1 ... 100 --> number of cycles
:asd <1 ... 100>
Steps Down
1 ... 100 --> number of steps to reach the end point
:asu <1 ... 100>
Steps Up
1 ... 100 --> number of steps to reach the end point
:ate <0 ... 10000>
Delay time at the end point (phase 13)
1 ... 10000 --> time in seconds
:ath <1 ... 10000>
Hold time (phase 10 and 16)
1 ... 10000 --> time in seconds
:atp <1 ... 10000>
Pause time (phase 18)
1 ... 10000 --> time in seconds
:atr <1 ... 10000>
Tolerance band
1 ... 10000 --> tolerance in 0.01 % FS (full scale) of the
instrument measuring range. Once the instrument has
been controlled within this tolerance band for 1 second,
the hold time expires.
:ats <1 ... 10000>
Start delay (phase 2)
1 ... 10000 --> time in seconds
Interface output
:o <0 | 1>
Output status information over interface
0 --> off
1 --> on
:pa <-110 ... 110>
Increase the set pressure demand by x percent -110 ...
+110 --> change in set pressure demand in %
:pd
Decrease set pressure demand by currently-set step size
in % (Step
DOWN
).
:pr <-1100 ... 11000>
Adjust the current working and measuring ranges -1,100
... +11,000
--> new measuring range in 0.01 % FS
:ps <-10 ... 110>
Percentage set pressure demand -10 ... +110 --> set
pressure demand in %
:pu
Increase set pressure demand by currently-set step size
in % (Step
UP
).
:saz<0 | 1>
Set auto zero (in measuring and control modes)
0 --> off
1 --> on
:sbr<0 ... 1>
Set baud rate RS-232
0 --> 1200
5 --> 19200
6 --> 28800
