CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example] Pt 100, 0 – 100°C, Output Type -10 – +10 V,

Output Range 1 – 5 V

Load resistance: Output drive 12 V max.

(e.g. 4 – 20 mA: 600 Ω [12 V ÷ 20 mA])

If not specified, the output range is 4 – 20 mA DC.

■ DC Voltage

Input Accuracy* (0.15°C**) ÷ Span (100°C) × 100 %

+ Max. Output Range (20 V) ÷ Span (4 V) × 0.04 %

= ±0.35 %

*Calculate the accuracy in °C.

Code V1 (narrow spans)

**100°C × 0.1 % = 0.1°C ≤ 0.15°C. 0.15°C is used as input

accuracy value.

Conformance range: -3 – +3 V DC

Output range: -2.5 – +2.5 V DC

Minimum span: 250 mV

Code V2 (wide spans)

Conformance range: -11.5 – +11.5 V DC

Output range: -10 – +10 V DC

Minimum span: 1 V

Offset: Lower range can be any specific value within the

output range provided that the minimum span is

maintained.

Load resistance: Output drive 1 mA max.
