æ1%
Source Resistance: <10
W for thermocouple input
Lead Resistance: <0.1
W/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.
DC Linear Inputs
Measurement Accuracy:
±0.25% of span ±1LSD.
Thermocouple Inputs
Measurement Accuracy:
±0.25% of span ±1LSD. NOTE: Reduced
performance with Type “B” Thermocouple
