CDT?
Output target value for zero displacement of input characteristic (for CDV
command) for all selected channels (PCS / SPS).
Syntax: CDT?(x)
Parameter: none
Response: q1(y): target value to which the current measured value is set
e.g. 0.01,0,0.5,0.502
Virtual subchannels (channel 9) do not support "dead load targets". q1=0.
CDV
Enter zero displacement of input (transducer) characteristic for all selected
channels (PCS / SPS)
Syntax: CDVp1 (x)
Parameter: p1:
No parameters: current measured value is adjusted to the target value entered
with CDT command (default: 0.0)
Therefore the current measurement value is needed. If the
status of one of the selected
subchannels is not valid a ? is responded !
Effect: additional zero point value (offset) which shifts the total char-
acteristic curve.
Explanation: displayed measval = gros (real measval without offset) – p1
Virtual subchannels (channel 9) do not support dead load values. Command
is ignored with OK answer.
Note: Response depends on SRB command.
