Calibrator Section
1)
The selection of frequencies as of 29 Hz is only possible within a limited raster.
Simulator for Temperature Sensors (resolution: 0.1 K)
2)
Without internal reference junction, relative to fixed external reference temperature
and thermovoltage of the thermocouple, internal reference junction: intrinsic error
of 2 K, external reference junction: entry of –30 60 C
