The service manual addendum for the Model 3011B Function Generator provides updated schematic diagrams and parts list information for units with serial numbers starting from 147-30253, reflecting modifications such as the addition of ZD601 and changes to the values of R602 and R629. It is intended to assist in the setup, operation, and troubleshooting of these modified units by detailing the specific component updates.
Manual Overview
The service manual addendum for the Model 3011B Function Generator provides updates for units with serial numbers starting from 147-30253. This includes the addition of a new component, ZD601, a 9.1 V, 500 mW Zener Diode, and changes to the values of resistors R602 and R629. Specifically, R602 is now a 20k ohm ±5%, 1/4 W carbon film resistor, and R629 is a 3300 ohm ±5%, 1/4 W carbon film resistor. The addendum includes a revised schematic diagram and parts list to assist technicians in servicing these updated units. For troubleshooting, technicians should refer to the updated schematic to ensure accurate diagnostics and repairs. The addendum does not provide specific error codes or calibration procedures, but the changes in component values should be considered during diagnostics and adjustments. Board-level guidance is implicit in the schematic changes, emphasizing the need to verify component values and connections against the updated documentation.
