Test Precautions

The output terminal of the power supply is as shown in Figure 1-1. The output
terminal is a metal conductor with certain contact resistance ( ) and when the
r ∆
output current of the power supply is , the voltage of this terminal is .

Therefore, during the test process, the voltage test point is always located at A to
reduce the error caused by the terminal voltage as far as possible. Besides, the
contact resistance between this terminal and the power output wire/the voltage
feedback wire inside the instrument chassis can also cause error (about 2mV, called
).

When testing the load regulation rate, voltage peak-peak value and transient
response time, the test devices are connected to the output terminal via A and the
load resistor is connected to the output terminal via B.

During the test, please pay attention to shield the effect of the environmental space
radiation noise on the test effectively.

Test Result Record

Record and keep the test results of each test item. The test result record forms,
which provide all the test items and the corresponding performance specification
limits as well as spaces for users to record the test results, of all models of DP800
series programmable linear DC power supply are provided in "Appendix A: Test
Result Record Forms" of this manual.
