Test case:
constant voltage source is 24V, output current is 0-5A, normal working current
is 3A.
Test purpose
: Power Dynamics, Vp+, Vp-.
Setup steps:
1.
Press the key
to enter the mode selection page, press the up and down keys to
select SWEEP, and press the key
to enter the SWEEP test interface shown in Figure
3.28.
2.
As shown in Figure 3.28,in the SWEEP interface, press the key
to enter the setting
interface shown in Figure 3.29.
3.
Set the E-load according to the parameters shown in Figure 3.29. The load will be carried
for 0.1S from the frequency of 50Hz when high level is 3A and low level is 1A, and then switch
to 60Hz for 0.1S stepping of 10Hz. In this way, the load will stop to be carried until the
frequency reaches 1000Hz.
4.
After the setting is completed, press
to exit to the test interface, press the key
to
start/stop the test.
3.11 TIMING Time measurement
The E-load provides time measurement function with an accuracy of 0.1mS. Under the
predetermined load condition, the E-load automatically captures 2 trigger signals and
calculates the time interval. After the test is completed, the E-load shows the time interval
(Time) of the two triggers. Press the key
on the front panel of the E-load and select the
TIMING function to switch the test mode.
