Average data on 4-20 mA reading

I have some noise on my 4-20mA sensor and could like to average the data for a longer period of time. For the DT80 i see that i can use the ESn ( Extra samples ) command but i don't find any similar for the DT800.

Are there any similar functions in the DT800 unit?

Regards,
Erik

Good morning Erik,

There is no equivalent to the ES channel option but you can change some parameters to have the same effect.

Change the P11 to half your main frequency. In Australia the main frequency is 50 Hz so setting the main frequency to 25 Hz will double the sample period. Change P46 to 200. The DT80 will take 200 reading in P11 time frame and return the average.

Cheers,
Roger
