I have a Hobby Boards B1-R1-A which reads about 954 (millibars I presume).
Actual pressure here is 1000+.
Elevation about 20 feet.
Hobby Boards online calibrator indicates that the offset voltage should be
3.566.
I set the B1-R1-A voltage according to instructions in the Weather Toys
booK:
1. remove jumper
2. connect voltmeter to jumper pin 1 and ground
3. adjust pot to get 3.566 volts
but baro reading remains about 954.
Can I just turn the pot until baro reading is closer what I think is right?
(I have not tried this for fear of frying something.)
Any other suggestions?
Thanks,
Peter
