Re: [foxboro] Easy AIN question

I don't think you can invert the high and low scales, but you can play 
with KSCALE and BSCALE (e.g., -1.0 and 100 to get a 100 to 0 reading) to 
invert the reading.

Most of these transmitters have the option of current output inversion as 
well.

[foxboro] Easy AIN question






I have an application coming up where I would like to use a guided
radar level transmitter to measure the amount of free space remaining in
a vessel. Being somewhat of an I/A novice, I thought I'd ask the experts
before proceeding.=20
The guides will be 72" long. If I enter the scaling in reverse order, 72
as low and 0 as high, will the indication be inverted? 4mA=3D72 and
20mA=3D0? Thus the read out on the display will be the amount of =
uncovered
guide.
