Maintenance
Maintenance of the BBE 422A is limited to proper cleaning of the unit with mild household cleaner such as Formula 409""
or WindexThe chassis and cover are steel finished with a durable polyurethane paint, while the front panel is an anodized
aluminum extrusion.
There are no user replaceable parts and the unit should not be opened for any reason unless you are a qualified technician.
Calibration should be performed if parts are replaced or if a performance check-out indicates a problem with calibration.
Long term use has shown that over the life of this unit there is little or no drift of the components in the BBE 422A which
would cause a change in calibration. A very conservative design philosophy has resulted in a piece of equipment which runs
very cool and should give years of trouble-free service.
