DP1116A Performance Verification Manual 1-5
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 (
r∆
) and when the
output current of the power supply is
I
, the voltage of this terminal is
I
rVe ×∆=
.
Therefore, during the test, 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 2 mV, called Uoffset).
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.
Figure 1-1 Output Terminal
Test Result Record
Record and keep the test result of each test item. A test result record form which
provides all the test items and their corresponding performance specification limits
as well as spaces for users to record the test results, is provided in Appendix.
Tip:
It is recommended that you photocopy the test results record form before each test
and record the test results on the copies so that this form can be used repeatedly.

Preparations
When the power supply is in CV state, the main parameters to be tested include the
CV load regulation rate, CV linear regulation rate, CV ripple and noise, transient
response time, CV programming accuracy and readback accuracy.
Before performing the tests, select the appropriate voltage via the “voltage selector”
at the rear panel of the power supply according to the AC line voltage of the country
(220 will be selected in all the tests in this guide). Under normal temperature (about
25℃), make connections according to the figure below using the devices
recommended in “Recommended Test Devices”. During the test, please set the
voltage of the AC power supply according to the voltage setting selected.
Note:
During the test, if two multimeters or a multimeter and an oscilloscope need to be
connected to the power supply, please connect the two instruments to the (+)
terminal and (-) terminal of the output terminal of the power supply respectively
using separate connecting wires to avoid coupling effect. It is recommended to use
coaxial cable or shielded two-wire cable to avoid causing noise.
