How to Use this Manual
This manual describes how to verify and adjust the performance of PSP-603/
405/ 2010 Programmable Switching D.C. Power Supplies.
Specification, page5, shows PSP electronic and mechanical specifications.
It also shows the locations of relevant verification and adjustment
procedures in this manual.
Front Panel, page6, describes the front panel switches, terminals, and
indicators. The Default Settings column shows the basic panel settings
applicable to all verification and adjustment items.
Performance Verification, page7, shows how to verify PSP performance,
step by step. Check the necessary equipment and the overall procedure
before start working on each item.
Adjustment, page17, shows how to adjust PSP specification. Same as
Performance Verification, check the equipment and the overall procedure
before start working on each item.
