Command Reference
Enters the Steinhart-Hart equation constants for temperature measurement.
Three <nrf values>, for the three Steinhart-Hart equation constants. The range of
acceptable values for each constant is -9.999 - 9.999. These values are scaled by the
appropriate exponential value for the Steinhart-Hart equation.
The default value for each constant are the typical values for an uncalibrated 10k
thermistor shown below. When all three constants are zero, the temperature display is
disabled and the open sensor and temperature limit error LEDs are disabled and will not
disable the output.
Typical values to use for an ILX Lightwave uncalibrated 10 k thermistor are:
C1 = 1.125 (x10
All three values must be entered. If one or more values are missing, error E-126 will be
generated.
"LAS:CALT 1.234,1.324, 1.234" -action: Sets C1 to 1.234, C2 to 1.324, and C3 to 1.234.
"LAS:CALT 0,0,0" -action: Sets all three constants to zero and disables temperature
measurement.
Returns the values of the Steinhart-Hart equation constants for temperature
measurement.
None.
The default value for each constant are the typical values for an uncalibrated 10k
thermistor shown below. When all three constants are zero, the temperature display is
disabled and the open sensor and temperature limit error LEDs are disabled and will not
disable the output.
Typical values to use for an ILX Lightwave uncalibrated 10 k thermistor are:
C1 = 1.125 (x10
"LAS:CALT?" -response: "1.125,2.347,0.855" means C1 = 1.125, C2 = 2.347,
and C3 = 0.855.
