SENSe3:STRain:EXCitation {<voltage> | MIN | MAX | DEF}, (@<ch_list>)
SENSe3:STRain:EXCitation? {(@<ch_list>) | MIN | MAX | DEF}
Sets the excitation voltage applied to the bridge by an external DC voltage source on the specified channels. This
value will be used to convert strain bridge measurements.
This SCPI is supported on the DAQM909A Digitizer module only.
Parameter Typical return
<voltage> = Any numeric value between 0.9 V to 12 V.
MIN: 0.9 V
MAX: 12 V
DEF = 5 V
+5.000000E+00
Specifies the excitation voltage as 5 V on Digitizer channel 201:
SENS3:STR:EXC 5,(@201)
SENSe3:STRain:GFACtor {<gage_factor> | MIN | MAX | DEF}, (@<ch_list>)
SENSe3:STRain:GFACtor? {(@<ch_list>) | MIN | MAX | DEF}
This SCPI is supported on the DAQM909A Digitizer module only.
Sets the gage factor to be used to convert strain bridge measurements on the specified channels. Gage factor is
defined as the ratio of the fractional change in resistance to the fractional change in length (strain) along the axis of
the edge.
Parameter Typical return
<gage_factor> = Numeric value between 0.5 and 5
MIN: 0.5
MAX: 5
DEF: 2
+2.000000E+00
Set gage factor as 2 for Digitizer channel 201
SENS3:STR:GFAC 2,(@201)
– Gage factor is a dimensionless quantity. The larger the value, the more sensitive strain gage.
