Earlier this week, I was working with one of our Honeywell Trendview X-series paperless recorders. The X-Series is capable of accepting data input from a USB barcode scanner — typically used for batch identification or for user name logins — but mine wasn’t working right.
When I tried to scan a barcode, I got an error message, and it stumped me. Luckily, I figured it out in a few minutes.
When you’re dealing with process recorder functions, some actions don’t like negative values, like a totalizer that sees a negative offset at zero flow as backflow, which impacts the total. But on the Honeywell X-Series paperless recorders, you can work around the issue, so they report only the positive values.
