Object under test:
constant voltage source 24V, output current 0-5A, normal working
current 3A.
Purposes:
to test power supply dynamics characteristic, Vp+, Vp-
Operation steps:
1.
Press the key
to enter the mode selection page, press the up and down keys to
select DYNA, and press the key
to enter the DYNA test interface, as shown in
Figure 3.16.
2.
In Figure 3.16, press the key
to enter the setting interface, as shown in
Figure
3.17.
3.
As shown in Figure 3.17, set the test mode to continuous test, high current Ib=3A,
high time Tb=1mS, low current Ia=1A, low time Ta=1mS,rise/fall rate=3A/uS.
4.
After the above settings are completed, press
to return the test interface, and
press
to start the test.
5.
Observe the values of Vp+ and Vp- during the test.
3.7 Battery test function
The CC,CP and CR mode can be applied for battery-capacity test with discharge
conditions. Discharging time and discharged capacity (AH or WH) of the battery can be
always observed during the test.
When the battery discharge meets the setting
termination conditions, the E-load will completes the test and stop loading.
