PERFORMANCE

Reference Conditions

Generally as EN60546-1.

Ambient Temperature:	20C 2oC
Relative Humidity:	60 -	70%
Supply Voltage:	90 -	264V AC 50Hz 1%
Source Resistance:	<10 for thermocouple input
Lead Resistance:	<0.1/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
	between 100 - 600C (212 - 1112F).

Linearisation Accuracy:

Cold Junction

Compensation:

RTD Inputs
