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.
