This manual covers the Bird Model 43 Wattmeter, and also covers models 4305, 4330, 4331, 4431, 4521 through 4527 and 43P. It is scanned from the original OEM paper manual. The scans came out very well, and all information available in the original manual is available and readable here. The pages are supplied as a single text-searchable PDF file. Adobe Acrobat Reader, which is required to view and/or print the manual, is also supplied on the CD. The Manual sections are: Safety Precautions, About This Manual, Introduction, Theory of Operation (OUTSTANDING!), Installation, Operating Instructions, and Maintenance. Please note that this is NOT the smaller, free manual distributed on internet free manual sites. Neither of the free manuals are as complete, ours being the full manual as provided by the manufacturer when you purchase the instrument.
The pages are completely readable and are fine for folks who need information. Manual collectors, though, and students of scanning techniques are asked to search elsewhere. Technical people in need of technical information will be very happy with the readability of the material.
