MANUAL SUPPLIED WITH MY 00899 RAIN GUAGE IS WRONG.The manual for MY rain gauge #00899 says that one cup of water is 2.2 inches of rain. ALSO , MY MANUAL SAYS, CW TO INCREASE . ONLINE INFO SEEMS TO BE RIGHT!! 1.68" AND CW TO DECREASE!! THIS CAUSED ME TO TRY FOR 4-6 HOURS TO CALIBRATE BEFORE FINDING THE ON LINE MANUAL.
