fixed value settings (such as Vset, Rset or Pset). After setting and entering the test,
press the ON button on the panel to load. Please refer to chapter 5.1 step 4 for
details.
5. In the test operating interface, users can see the operating process and result data,
such as Time, Vpp, etc.
6. After pressing the ON button on the panel, press the [EXIT] button to exit the fast
charge mode and return to the main measurement interface.
5.6 DPDN Test
In the main interface of the electronic load, press the corresponding soft key at the bottom
of the screen to enter the setting interface. The DPDN mode is initialized according to the
BC1.2 protocol. After the initialization, the power supply type will be given, and the test
interface will display the voltage on the D+ and D- data leads of the current measured
object in real time.
Steps to enter the DPDN test interface:
1. Press the power button to turn on the electronic load. In the main measurement
interface (the default main measurement interface is CC mode when the instrument is
turned on), press the soft key [DPDN] at the bottom of the screen to enter the <
DPDN> display interface. If it is not on the main measurement interface , users can
press the button [Mode], then select the soft key [Fast Charge] to enter the fast
charge horizontal bar selection interface, and finally enter the <DPDN> display
interface by pressing the soft key [DPDN].
2. After entering the DPDN mode interface, the electronic load will automatically have a
handshake with the measured object:
During the handshake/operating process, the indicator at the top right of the screen is
red, otherwise it is white.
If the handshake is successful, the status will be displayed as [OK], as shown in the
upper right corner of Figure 5-6, otherwise it will be displayed as [Err].
