Com ma nd Reference
The CONST:ICV? query returns the slope and offset coefficients for a voltage IC sensor.
The response is two values. The first represents the slope. The second represents the
offset.
CONST:ICV? response: 4.2, -3.0 means a slope of 4.2 mV / K and an offset of -3.0 mV
for the voltage IC sensor coefficients.
The CONST:RTD command sets the A, B, C and Ro coefficients for an RTD sensor.
Four <nrf values> are required. The first represents the A coefficients, the second is the
B coefficient, the third is the C coefficient and the fourth is the Ro, in Ohms. The scale
factors for A, B, and C are programmed into the instrument and are as follows: A*1E-03,
B*1E-07, and C*1E-12.
Acceptable values for A, B, and C are -99.99 to +999.99. Acceptable values for Ro are 0
to 99,999.99 Ohms. RTD coefficients are typically supplied by the manufacturer.
CONST:RTD 3.4, 7.0, 5.0, 100.1 action: sets the RTD coefficients as follows: A=3.4,
B=7.0, C=5.0, Ro = 100.1
The CONST:RTD? query returns the A, B, C and Ro coefficients for an RTD sensor
The response is four values that represent the values of A, B, C, and Ro in that order.
These values are pre-scaled so that the exponential value is not given. The actual value
of A is scaled by 10E-03, B by 10E-07, and C by 10E-12.
CONST:RTD? response: 3.4,7.0,5.0,100.1: The RTD coefficients are A = 3.4, B = 7.0,
C = 5.0 and R
0
