The TEC:COND? query returns the value of the status condition register of the TEC
operations.
Notes The enabled TEC conditions can be set by using the TEC:ENABle:COND command.
The TEC condition status is constantly changing, while the event status is only cleared
when the event status is read or the *CLS command is issued.
Examples "TEC:COND?" -response: 513, means that the Output Out of Tolerance and TE Current
Limit TEC conditions currently exist.
"Radix Hex; TEC:Cond?" -response: #H82, means that the TE Module Open and Voltage
Limit TEC conditions currently exist.
The TEC:CONST command sets the TEC's Steinhart-Hart equation constants.
Parameters One, two, or three <nrf values>, for the three Steinhart-Hart equation constants or the
two linear calibration constants for linear IC sensors. With v1.9 and higher, the range of
values is -99.999 to +99.999 for all three constants (previously was -9.999 to +9.999).
However, for a thermistor sensor, these values are scaled by the appropriate exponential
value for the Steinhart-Hart equation.
Notes If less than three parameters need to be changed, only the desired change needs to be
specified, along with the separating commas (see examples).
When the LM335 or AD590 sensors are selected via the SENSOR SELECT switch, only
C1 and C2 are used. Therefore, only two parameters are required in those cases.
Examples "Tec:CONST 1, 2.33, 0.5 " -action: sets C1 to 1.000, C2 to 2.330, and C3 to 0.500.
"TEC:const 1.4, ," -action: sets C1 to 1.400, C2 and C3 unchanged.
"TEC:Const ,4.5,0.3" -action: sets C2 to 4.500, C3 to 0.300, and C1 is unchanged.
"Tec:CONST 1.4,2.015" -action: sets C1 to 1.400, C2 to 2.015 for two-point calibration of
AD590 or LM335 sensors (C3 is unchanged, but not used).
