Question: Where can I get the WFM601 A+ E+ or M calibration software?
Answer: Click the link below to download the WFM601A/E/M calibration software which normally comes on a floppy disk bundled with the service manual for these instruments. Once downloaded, unzip this archive and copy the contents of it to a floppy disk. Then run the CAL.EXE program from that floppy disk on a PC running DOS. From here the software and the WFM601A/E/M service manual should walk you through the necessary steps for calibrating your instrument.
NOTE: This software is intended for the WFM601A, WFM601E or WFM601M. The WFM601i and non-lettered models use different calibration software.
NOTE: You will need to run this software on a PC that is running true MS-DOS. Simply running the software in a DOS command windows within Windows will not work because the tool needs access to hardware ports which are protected under Windows operating systems.
