Operating influence

The percentages refer to the configured measuring span.

Input terminal voltage effect / load effect:

Within the specified limit values for the voltage / load, the total influence is less than 0.001 % per volt.

Normal-mode rejection ratio:

> 65 dB at 50 / 60 Hz

Common-mode rejection ratio:

> 120 dB at 50 / 60 Hz

Ambient temperature influence:

Based on 23 °C (73.4 °F) for an ambient temperature range of −40 to 85 °C (−40 to 185 °F)1)

Sensor

Ambient temperature effect per 1 °C (1.8 °F) deviation from 23 °C (73.4 °F)
