ends.
2. Pulse: Lower parameters will be on-loaded at first, and then the load will switch to an
upper value each time when it receives a trigger signal, and it will switch back to the
lower value at the end of the set time. In pulse mode, lower timing is not necessary
because the reverse action will be triggered only once when one trigger signal is
received.
3.
Reverse: Each trigger will lead to the switching between the high and low value, and
upper/lower timing is not necessary at this time. Only after each trigger will it switch to
another status.
The users can set the parameters according to their own needs. The following figure 4-1-5
shows the low and high current values set in dynamic CC mode. The load will
continuously switch back and forth between these two values.

Operation steps:
1. After starting up, first press the CH button to select the operating channel. The yellow
wireframe area is the selected channel. And CH1 or CH2 will be displayed at the top
of the screen (UTL8212 only).
2. Press the Mode button to enter the mode selection interface, select the dynamic
mode with the pulse knob or direction buttons, and then press Enter to enter the
dynamic mode setting interface.
3. Select the modified parameter with the pulse knob, press Enter to modify, and press
Enter again to save the modification.
4. After setting the parameters, press the ON button to enter the dynamic test interface
(channel 1: ON1, channel 2: ON2).
5. Press the ON button to start the operation, and press the ON button again to stop it.
Note:
If the voltage position/current position is set to the low position, when the
voltage/current value exceeds the range of the low position during load operation, the
error information will be displayed. The users should return to the parameter setting
interface, and refer to chapter 5.2 to adjust the voltage/current position.
