Performing The Tests
General Measurement Techniques
Figure C-1 shows the setup for the tests. Be certain to use load leads of sufficient wire gauge to carry the output current (see Table 8-1). To avoid noise pickup, use coaxial cable or shielded pairs for the test leads.
Programming the Power supply
Appendix A lists the programming voltage and current ranges. Enter the appropriate values from the front panel. The programming procedures assume you know how to operate the power supply from the front panel (see "Chapter 5 - Front Panel Operation").
Order of Tests
Perform the following tests for operation verification. Test 1 must be done first, followed by Tests 2 and 3 in any order.

Action
Turn off the power supply and connect a DVM across the sense terminals (see Figure
Turn on the power supply with no load and program the output for 0 volts and maximum programmable current.
Record voltage readings at DVM and on front panel display. (Subtract or add the specified readback limit to the actual output values).
Program voltage to full scale.
Record voltage readings of DVM and on front panel display. (Subtract or add the specified readback limit to the actual output values)
Normal Result
CV annunciator on. Output current near 0.
Readings within Low Voltage limits (see applicable test table).
Readings within High Voltage limits (see applicable test table).
