■ Specifications
● PV input
Input type: Thermocouple K, J, E, T, R, S, B, N (JIS C1602-1995)
PL II (Engelhard Industries data(ITS90))
WRe5-26 (ASTM E988-96(Reapproved 2002))
DIN U, DIN L (DIN43710-1985)
RTD Pt100 (JIS C1604-1997), JPt100 (JIS C1604-1989)
DC voltage 0 to 1Vdc, 1 to 5Vdc, 0 to 5Vdc, 0 to 10Vdc
DC current 0 to 20mAdc, 4 to 20mAdc
Sampling cycle time: 500ms
Indication accuracy:
±0.5%FS±1 digit, ±1%FS±1digit in the negative area of the thermocouple
(Specified by the input conversion at an ambient temperature of 23±2˚C)
However, the accuracy of the B-thermocouple is ±5%FS at a temperature
of 260˚C or less and ±1%FS at a temperature of 260 to 800˚C.
The low limit for indication is 20˚C. However, if ROM version 1 of the
instrument information bank (Id02) is prior to 2.04, the low limit for
indication is -180˚C.
