HOW TO CALCULATE THE ACCURACY
■ Overall Accuracy
Offset: Lower range can be any specific value within the
output range provided that the minimum span is
maintained.
[Example] Total resistance 800 Ω, 250 – 750 Ω input, 1 – 5 V
output
Input Accuracy
Load resistance: Output drive 6 V max.
(e.g. 4 – 20 mA: 300 Ω [6 V ÷ 20 mA])
■ DC Voltage: -10 – +10 V DC
= Max. Range ÷ Input Span × Input Accuracy
= 800 ÷ 500 × 0.01
= 0.02
Operational range: -11.5 – +11.5 V DC
Minimum span: 1 V
Output Accuracy
= Max. Range ÷ Output Span × Output Accuracy
= 20 ÷ 4 × 0.02 = 0.1
Overall Accuracy
Offset: Lower range can be any specific value within the
output range provided that the minimum span is
maintained.
= 0.02 + 0.1
Load resistance: Output drive 1 mA max.
(e.g. 1 – 5 V: 5000 Ω [5 V ÷ 1 mA])
If not specified, the output range is shown below.
V2Z1: 1 – 5 V / 4 – 20 mA DC
= ±0.12 %
V2V2: 1 – 5 V / 1 – 5 V DC
INSTALLATION
Current consumption: Approx. 50 mA (70 mA for current
output)
Operating temperature: 0 to 55°C (32 to 131°F)
Operating humidity: 30 to 95 %RH (non-condensing)
Mounting: Installation Base (model: M8BSx)
Weight: 70 g (2.5 oz)
PERFORMANCE
Overall accuracy:
Input accuracy + output accuracy [gain ≤ 1]
(inp. accuracy + out. accuracy) × gain [gain > 1]
Inversely proportional to the span.
