the command initializes the two-point calibration sequence, where two
temperatures must be simulated.
When you type
TCAL TS DTS14B_temperature
↵ ↵↵ ↵
a single-point calibration to the TS is made. That is, the scaling factor
TS 0 is adjusted by the command routine.
The following command
TCAL TS 0.0
↵ ↵↵ ↵
makes a zero calibration, if the temperature sensor DTS14B is in an
ice bath or otherwise at a temperature of 0 °C .
The following command
TCAL TS 0.0581 -59.0
↵ ↵↵ ↵
sets both scaling factors.
The system output is as follows:
DRI TEMPERATURE SCALES
TS 1 0.0581 TS 0 -59.0000 TS 2.8
