Selectable range: -7.5 to +107.5 % as input %; -7.5 to +107.5 % as output) ■ Low-end Cutout:Low-end cutout (Low Cut) point selectable within the range of 0 to 100 %. With linear or segment linearization, the output signal is forcibly set to 0 % for the input lower than the low-cut point. With the square root extraction, the output signal is linear to the input when the latter is lower than the low-cut point.

PERFORMANCE

Accuracy: Input accuracy + output accuracy

See CALCULATION EXAMPLES OF OVERALL ACCURACY. Inversely proportional to the setting span. Except the accuracy of input resistor. Input accuracy: (% of max. input range) Input accuracy differs depending on the linearization type. Linear: ±(0.04 % of FS) Square root extraction (1 % or more of input): ±(0.1 % of FS) Segment linearization: ±(0.04 % of FS) [gain ≤ 1] ±(0.04 % x gain of FS) [gain > 1] Display accuracy: Input display: Input accuracy ±1 digit Output display: Input accuracy + output accuracy ±1 digit Output accuracy: ±0.04 % of max. output range Temp. coefficient (% of max. I/O range): ±0.015 %/°C (±0.008 %/°F) Response time (filter time constant: 0 sec.): ≤ 0.5 sec.

(0 – 90 %) Line voltage effect: ±0.1 % over voltage range Insulation resistance: ≥ 100 MΩ with 500 V DC Dielectric strength: 2000 V AC @1 minute (input to output to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Input Range: 0 – 20 mA, Input Setting: 4 – 20 mA, Output Range: 0 – 20 mA, Output Setting: 4 – 20 mA (when the linearization type is linear) ■ Overall accuracy

• Input Accuracy = Input Range Span (20 mA) ÷ Input Span Setting (16 mA) × 0.04 % = 0.05 %
• Output Accuracy = Output Range Span (20 mA) ÷ Output Span Setting (16 mA) × 0.04 % = 0.05 % Overall Accuracy = 0.05 + 0.05 = ±0.10 %
