Variation in indicated value due to input conversion when the wiring resistance at both ends
is 250Ω
• 0 to 10mV, -10 to +10mV : 35µV or less
• 0 to 100mV,
• Others
±0.01% FS/Ω max. in a wiring resistance range of 0 to 10Ω
±0.02% FS/Ω max. in a range with a minimum resolution of 0.01°C
The allowable wiring resistance is 85Ω max (A zener barrier is available only for the 0.1°C
resolution range and requires on-site adjustment.)
the -200.0 to +500.0°C range of JIS Pt100 are not downscaled. The indicating
values lower limit for B input (0.0 to 1800.0°C) is 20°C .)
