Quick Guide 3. Parallel output Press Output Settings->Operation Mode to select Parallel, which can be set as parallel output. In parallel mode, the channels are internally connected in parallel to form a single output. The channel 2 window of the main interface displays "PARALLEL with CH1". Channel 1 is the master and channel 2 is the slave. The "+" and "-" binding posts of channel 1 are the two output terminals of the parallel circuit. The output current is twice the set current of channel 1, and the output voltage is the set voltage of channel 1. The external wiring method of parallel mode is as follows: 16
