348 VT1422A Command Reference
Chapter 7
[SENSe]
Note
Because of the number of possible strain gage configurations, the driver must
generate any Strain EU conversion tables and download them to the instrument when
INITiate is executed. This can cause the time to complete the first INIT command to
exceed 1 minute on some platforms, notably the Agilent/HP E1405B/06A.
Subsequent INITs (with no other configuration changes) do not need to regenerate
EU tables and execute much faster.
Parameters
Comments
•
Strain measurements require the use of Bridge Completion Signal Conditioning
Plug-Ons or a Remote Strain Bridge Conditioning Unit.
•
Bridge Completion SCPs and RSCs provide the strain measurement bridges and
their excitation voltage sources.
<ch_list>
specifies the voltage sensing
channels that are to measure the bridge outputs. Measuring channels on a Bridge
Completion SCP only returns that SCP's excitation source voltage.
•
The VT1422A has five ranges: 0.0625 V dc, 0.25 V dc, 1 V dc, 4 V dc, and
16 V dc. To select a range, simply specify the range value (for example, 4 selects
the 4 V dc range). If a value is specified that is larger than one of the first four
ranges, the VT1422A selects the next higher range (for example, 4.1 selects the
16 V dc range). Specifying a value larger than 16 generates an error. Specifying
0 selects the lowest range (0.0625 V dc). Specifying AUTO selects auto range.
The default range (no range parameter specified) is auto range.
