WE2107 - Communication commands
I1820-1.3 en HBM
Preparing for data output
1. Use the COF
command to define the output format
2. Use the NOV
command to define output scaling
3. Use the RSN
command to define display resolution
4. Use the DPT
command to define the decimal point position
5. Use the MRA
command to define the mode of operation
6. Use the FMD
command to define the digital filter mode
7. Use the ASF
command to define the digital filter
The output scaling is defined by the parameter of the NOV command.
Output format measured value at max. capacity
NOV w 100
2‐byte binary NOV value
4‐byte binary NOV value
ASCII NOV value
With 2‐byte binary output, the NOV value must be v 30000, otherwise the measured value
will be output with overflow or underflow (7FFF
H
or 8000
H
, H: hexadecimal). With
NOV30000, the overload reserve is only about 2700 digit.
The measured value is stored in the output buffer independently of the measurement query.
Binary output:
The length specification includes the end label (CR, LF).
With 4‐byte output, the measured value is a 3‐byte value. The fourth byte is the
measurement status
COF Length Sequence for data output
COF0 4 bytes MSB before LSB
COF1 4 bytes LSB before MSB
COF2 6 bytes MSB before LSB (LSB = status)
COF3 6 bytes LSB before MSB (LSB = status)
MSB=most significant digit, LSB=least significant digit
