A 3.4.6.2 MASTERMV, Mastering / Zeroing
MASTERMV NONE|MASTER <MV>
- NONE: completes mastering
- MASTER: sets the current measurement value as a master value
- MV: master value in millimeters; MV = (0 ... 2) * measuring range, i.e. master value must be within
measuring range
In case of master value is 0, the mastering has the same functionality as the zeroing. The parameter MV
always operates independently from an input as zeroing during mastering the analog output.
The master command awaits the next measurement value, a maximum of 2 seconds, and masters it. If no
measurement value is received within this time, for example, by external triggering, the command returns with
the error “E104 Timeout“.
The master value is processed with six decimal places.
Note that the output value is limited to 18 bits.
A 3.5 Data Output
A 3.5.1 OUTPUT, Selection of Measurement Value Output
OUTPUT NONE|RS422|ANALOG
- NONE: no measurement value
- RS422: output of measurement value via RS422
- ANALOG: analog output of measurement values
A 3.5.2 OUTREDUCEDEVICE, Output Reduction of Measurement Value Output
OUTREDUCEDEVICE NONE| ([RS422] [ANALOG])
Selection of interface for data reduction.
- NONE: no data reduction
- RS422: data reduction for RS422
- ANALOG: data reduction for analog output
