Channels
Setup Example (1) of Thermocouple Input
Set channel 02 to thermocouple type K and measure temperatures in the range –50.0 to
450.0°C. The measurable range for thermocouple type K is –200.0 to 1370.0°C.
The measured values in the range of –50.0 to 450.0°C are recorded in a width of 180 mm
on the chart paper. This recording range is called a recording span, and the leftmost and
rightmost values of the recording span are called span left and span right, respectively.
