The LIMit:Temp:LOw? query returns the value of the lower temperature limit setting.
The response is a single value that represents the lower temperature limit.
Low temperature limit is valid for all modes of operation except R
LIM:T:LO? response: 55.0, means the lower temperature limit is 55.0
The LIMit:TOLerance command sets the controlled setpoint tolerance limit.
An <nrf value> that represents the tolerance is required. When the controlled quantity
(temperature, sensor, current, or voltage) is within the tolerance window, the load is
considered "in tolerance" and trigger out high will be set. The tolerance window is
defined as the setpoint +/- tolerance limit.
The range of the tolerance window is 0 to 99.999. The units of this parameter depend on
the mode of the instrument. In constant temperature mode, the units of the tolerance
window are in degrees C, and constant voltage mode, the units are in V, in constant
sensor mode the units depend on which sensor is selected (Amps for ICI, Ohms for
thermistor and RTD, Volts for ICV,) etc. If the tolerance window is set too tight, the output
may never reach tolerance.
LIM:TOL 0.01 action: Sets the tolerance limit to +0.01
mode). The output trigger will go high when the temperature is within +0.01
setpoint.
The LIMit:TOLerance? query returns the value of the controlled setpoint tolerance limit.
The response is a single value that represents the tolerance.
The units of the tolerance window match those of the mode (and in some cases the
sensor type) of the instrument.
LIMit:TOL? response: 0.005 means a tolerance window of +0.005k , (if the instrument is
set to Sensor mode, with a thermistor as the sensor)
