8 Digital Temperature Controllers E5CN/E5CN-U
■ Characteristics
Note: 1. The indication of K thermocouples in the −200 to 1300°C
range, T and N thermocouples at a temperature of
−100°C
max., and U and L thermocouples at any temperature is
±2°C ±1 digit maximum. The indication accuracy of the B
thermocouple at a temperature of 400
°C max. is not
specified. The indication accuracy of the R and S
thermocouples at a temperature of 200
°C max. is ±3°C ±1
digit max.
2. “EU” stands for Engineering Unit and is used as the unit
after scaling. For a temperature sensor, the EU is
°C or °F.
3. When robust tuning (RT) is ON, the differential time is 0.0 to
999.9 (in units of 0.1 s).
4. B, R, and S sensors: 0.2
°C/Ω max. (100 Ω max.)
■ USB-Serial Conversion Cable
Note: A driver must be installed in the personal computer. Refer to
installation information in the operation manual for the
Conversion Cable.
■ Communications Specifications
Note: The baud rate, data bit length, stop bit length, and vertical
parity can be individually set using the Communications Setting
Level.
