[M91 Analog Input 4-20ma not reading correctly]

Thanks for your help.

We ordered another one, and you were right on with the signal generator. I was using it incorrectly as I was connecting it the same as the 2 wire transducer but it was self powered. The first unit was faulty as the second unit when installed operated correctly.

Thanks

[M91 Analog Input 4-20ma not reading correctly]

Im having an issue with a M91-2-r2-c Analogue input raw values.

I have set jumpers 3 and 4 to B and have configured software for 4-20ma. On 4ma on multimeter I get a raw value in my MI register of 9, and 20ma I get 45.

I also changed M91 and software to 0-10v with the same outcome with the raw values. I have been using a signal generator to mimic these values.

This is the first time I have used these 91s on Analog and are wondering if I have missed something or the unit is faulty.

Thanks for any assistance.
