(measuring range module must be in position C) Best regards, Wizard

I hope this helps

how come Posts: 382 Rating: (47)	Hi, Apart from Wizard and fritz valuable advises, since you configured as 2DMU, what you can do to confirm the channel is ok is to use the meter to measure thechannel of the AI card. Put your meter to DC measurement. You should get some DC volts [approximate 22 to 24vdc] from the channel. If not then maybe the channel already faulty. Try the next channel. with regards, how come
