VT1422A Command Reference 307
MEASure
•
This command executes a measurement scan without running defined
algorithms. This is to keep algorithms from placing values in the FIFO buffer.
•
The measurement sample interval is 392 µs
•
Filter settings and states are not changed by this command.
•
Note also that shunt resistor source and state are left as currently programmed.
•
After completing the measurements, the instrument is re-configured to the same
settings that existed before the command was executed.
•
When Accepted: Not while INITiated
•
Related Commands: SENSe:STRain:EXCitation, MEAS:VOLT:UNST?
•
*RST Condition: Channel unstrained values are not affected by *RST.
However, *RST changes the function for all analog input channels to Voltage.
When a strain channel is changed back to the strain function with a
SENS:FUNC:STRAIN... command, the unstrained values for these channels
will still be in effect. Of course, loss of power will cause the unstrained values
to be lost.
•
Returned Value: numeric, number of channel values in FIFO. The type is int16.
•

Usage
MEAS:VOLT:UNST? (@10000:10931)
determine unstrained voltage on 128
strain channels through VT1539As in
SCP positions 0 and 1
SENS:DATA:FIFO:RESET
As in most cases, since the values have
been sent to the strain EU conversion,
the individual unstrained values do not
need to be seen.
