WS-1090 humidity issues
Posted: Tue Jul 24, 2018 1:03 am
We have sorta discussed this issue before, but now that I have moved and literally living in a desert zone, I wonder if a, hopefully, change can be made. The WS"1090 will only read between 10% humidity and 99% humidity, it displays a double dash on the console and (apparently) reads 0% humidity to MB. Using the humidity stretch option I used to be able to handle it by simply setting humidity stretch to have - 2 be 0%. Where I lived, we almost never got < 10% humidity.
Now that I have moved to a desert zone, we very often get humidity < 10%. Almost daily in fact for the last month.
When the console reports to MB 0% RH the dewpoint drops off scale... No surprise there.
What I would hope for is when the supposed humidity drops below a user selected minimum reading (in my case 10%) that MB uses a user set value instead to calculate dewpoint.
MINIMUM HUMIDITY. 10 USE 5 TO CALC. DP
This way, DP won't drop off the chart.
I have tried to set the stretch to -10 is 0 but when MB reads the NULL or 0 (I am not sure what the console outputs when <10%) MB still calculates a way low DP
Any thoughts on a software fix for this?
