Preparation
The main parameters of DP1308A requiring test under constant voltage include
constant voltage load adjustment rate, constant voltage linear adjustment rate, ripple
and noise, transient response time as well as programming and readback accuracy.
Before the test, select the appropriate voltage (for the voltages supported by
DP1308A, refer to Table 2-1) via the “voltage selector” at the rear panel of the power
supply according to the AC line voltage of your nation. Connect the device
recommended in Recommended Test Devices according to the figure below under
normal temperature (about 25
℃
). During the test, set the voltage of the AC source
according to the voltage selected.
