Inquiry (采购产品): RH-3A Air Flow Switch Calibration I work for Omaha Public Power District, and we purchased 2 of your RH-3A Air Flow Switches in the not-too-distant past. I am wondering what website I can go to to find out how to perform a bench cal prior to installation, or if you could send me information on how to do the bench cal. Thank you, Larry Lees. **** Hidden Message ***** Larry Lees 4227 N. 139th Ave. Omaha, NE 68164-5024 USA Company: Omaha Public Power District Title: Field Engineer Fax: 402-533-6940 E-mail: llees@oppd.com **** Hidden Message ***** llees@oppd.com
