CHAPTER 2 Checks and Preparation
Item Description
Thermocouples K, J, E, T, R, S, B, N, C (WRe 5-26)
Resistance bulb Pt100, JPt100, Pt1000 (IEC751)
A/D resolution 16-bit (Effective resolution: Approx. 1/40,000 of the +/- range)
Filter Off, 2, 5, 10, 20, 40
Filter operation is on a moving average basis.
The average value of the set sampling count is used.
If the sample interval exceeds 30 seconds, the average value of data
obtained in a sub-sample (30 seconds) is used.

DC voltage input Thermocouple input
Resistance bulb input DC current input
DC voltage
Compensation wire
The lead wire resistance per line should
be 10Ω or less, and the resistance values
of the three lines should be equal.
Shunt resistance
Ex: For 4-20mA, add 250Ω (± 0.1%) and measure
in the 1 - 5V range.
