Output
Eect of load impedance < 0.025% of max. span / 100 Ω
Long-term drift < 0.025% of max. span in the rst month
< 0.035% of max. span after one year
< 0.05% of the max. span after 5 years
Note
Measurement errors
Greater measuring errors may occur if the transmitter is installed on a DIN rail in an environment
with severe interference. Observe the applicable ESD directives.
