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 %
