Electromagnetic compatibility (EMC)
-
immunity: according to the PN-EN 61000-6-2:2002(U) standard
- emissivity: according to the PN-EN 61000-6-4:2002(U) standard
(1) - simulation of resistance (RTD,
Ω
) does not work for multiplexed inputs (pulse IP current)
(2) - when replacing the batteries, pay attention to the polarity shown in the battery compartment
