VT1422A Command Reference 307Chapter 7
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.
•Send with VXIplug&play Function: hpe1422_cmdInt16_Q(...)
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.
