Operation Verification Tests

Table 2-3 lists the requirements for operation verification, which is a subset of the performance tests.

Note: Record the results of Tests 2 and 3 in the appropriate Performance Test Record sheets

Performance Tests

Performance tests check all the specifications of the power supply. The tests are grouped into constant-voltage mode tests

(Table 2-4) and constant-current mode tests (Table 2-5).

Constant Voltage (CV) Tests

Test Setup

Connect your dc voltmeter leads to only +S and -S (see Figure 2-1), because the power supply regulates the voltage

between these points, not between the + and - output terminals .

Test Procedures

Perform the test procedures in Table 2-4. The CV tests are:

• Voltage Programming and Readback Accuracy

• CV Load Effect

• CV Source Effect

• CV Noise (PARD)

• Transient Recovery Time

Note The tests are independent and may be performed in any order.
