Specifications

To specify the temperature of a controlled temperature reference panel:
SENS:REF:TEMP 50 reference temp = 50 °C
Now begin scan to measure thermocouples
Linking Strain
Measurements
Strain measurements usually employ a Strain Completion and Excitation SCP
(VT1506A, VT1507A, VT1511A). To link channels to strain EU conversions send
the [SENSe:]FUNCtion:STRain:<bridge_type>[<range>,](@<ch_list>)
·
<bridge_type> is not a parameter but is part of the command syntax. The
following table relates the command syntax to bridge type. See the
VT1506A , VT1507A, and VT1511A SCPs’ user’s manuals for bridge
schematics and field wiring information.
Command Bridge Type
:FBENding Full Bending Bridge
:FBPoisson Full Bending Poisson Bridge
:FPOission Full Poisson Bridge
:HBENding Half Bending Bridge
:HPOisson Half Poisson Bridge
:[QUARter] Quarter Bridge (Default)
·
The <ch_list> parameter specifies which sense SCP channel(s) to link to
the strain EU conversion. <ch_list> does not specify channels on the
VT1506A/07A Strain Bridge Completion SCPs but does specify one of
the lower four channels of a VT1511A SCP.
·
The optional <range> parameter can be used to choose a fixed A/D range.
When not specified (defaulted), the module uses auto-range.
To link channels 40 through 43 to the quarter bridge strain EU conversion:
SENS:FUNC:STR:QUAR (@140:143) uses autorange
Other commands used to set up strain measurements are:
[SENSe:]STRain:POISson
[SENSe:]STRain:EXCitation
[SENSe:]STRain:GFACtor
[SENSe:]STRain:UNSTrained
For more detailed programming information, see the individual SCP manual.
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 INIT command
to exceed one minute.
