Note 2: The accuracy is 0.5C of instrument range 1 digit for a temperature range from -100 to 0C and 100 to 200C.

*1: Performance in the standard operating conditon (at 23C 2C, 5510%RH, and 50/60Hz power frequency)

*2: To receive a 4 to 20 mA DC signal, select a Standard signal of 1 to 5 V DC and connect it to a 250 Ω resistor.

This resistor is optional Model: X010-250-2 (resistor with M3.5 crimp-on-terminal lugs)

Burnout detection:

Functions at thermocouple (TC), RTD or

standard signal of 0.4 to 2 V or 1 to 5 V.

Upscale, downscale, and off can be specified.

For standard signal, set to burnout at 0.1 V or

less.

Input bias current: 0.05 µA for TC and RTD b-terminal

Measurement current(RTD): About 0.13 mA

Input resistance:

1 MΩ or more for TC or mV input

About 1 MΩ for DC voltage input

Allowable signal source resistance:

250 Ω or less for TC or mV input

Effects of signal source resistance:

0.1 µV/Ω or less

2 kΩ or less for DC voltage input

Effects of signal source resistance:

About 0.01%/100 Ω
