A.9 PERFORMANCE
Reference Conditions
Ambient Temperature: 20 ° C ± 2 ° C
Relative Humidity: 60 - 70%
Supply Voltage: 90 - 264V AC 50Hz
Source Resistance: <10 Ω for thermocouple input
Lead Resistance: <0.1 Ω /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.
