Operation verification tests
The following tests assure that the power supply is performing properly. They do
not, however, check all the specified parameters tested in the complete
performance test described below. Proceed as follows:
1 Perform “Turn-On Checkout Procedure” on page 33.
2 Perform Load regulation (load effect) given in the following paragraphs.
Line voltage option conversion
To convert the supply from one line voltage option to another, the following three
steps are necessary:
1 After making certain that the line cord is disconnected from a source of power,
remove the top cover from the supply and set the two sections of the line
voltage selector switch for the desired line voltage (see Figure 5-1 ).
2 Check the rating of the installed fuse and replace it with the correct value, if
necessary. For Option OE3, use a slow-blow 1.0-amp fuse. For standard and
Option OE9, use a slow-blow 1.6-amp fuse.
3 Mark the instrument clearly with a tag or label indicating the correct line
voltage to be used.
