times the span or ±50 mV
Within whichever is smaller, three
times the span or ±25 mV
Measuring range Changeable on Engineering Display
Input resistor 1 MΩ (3 kΩ at power failure)
External input resistor 500 Ω or less
Allowable input voltage
and current
−0.5 to 4 V DC
Input l linearization Not provided Provided
1 to 5 V output
conversion accuracy
rating
Within ±0.2% of span
Whichever is greater, ±0.2% of
span or input equivalent ±20 µV
Reference junction
compensation error
− Within ±1°C (*1)
*1: Type B does not conduct reference junction temperature compensation.
For types other than type B, the value obtained by multiplying the noted value by the following
coefficient (K) applies if the measurement temperature is 0°C or less.
K = (thermoelectric power for 1°C near 0°C) / (thermoelectric power for 1°C at measurement
temperature)
