A.11 PERFORMANCE
Reference Conditions
Generally as EN60546-1.
Ambient Temperature:
20°C ±2°C
Relative Humidity: 60 - 70%
Supply Voltage: 90 - 264V AC 50Hz 1%
Source Resistance: <10Ω for thermocouple input
Lead Resistance: <0.1Ω/lead balanced (Pt100)
Performance Under Reference Conditions
Common Mode Rejection: >120dB at 50/60Hz giving negligible effect
at up to 264V 50/60Hz.
Series Mode Rejection: >500% of span (at 50/60Hz) causes
negligible effect.
Thermocouple Inputs
Measurement Accuracy:
