RIGOL Chapter 2 Constant Voltage Tests
DP800 Performance Verification Manual
Preparations
When the power supply is in CV state, the main parameters to be tested include CV
load regulation rate, CV linear regulation rate, CV ripple and noise, transient
response time, CV programming 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
(230V is taken as an example in all the tests in this manual). Under normal
temperature (about 25℃), make connections according to Figure 2-1 or Figure 2-2
using the devices recommended in “Recommended Test Devices”. During the
test process, please set the voltage of the AC power supply according to the voltage
selected of the “voltage selector” at the rear panel of the power supply.
