2.2.3.3 While the two outputs in parallel, proper leads corresponding to
outputpower be used to short reliably the two positive terminals and the two
negative terminals of master & slave output separately, so as to make load
connected reliably with the two parallel outputs. If the load is only connected to
one of the output terminal, unbalance may be caused to current of the two outputs,
this may also damage the series/parallel switch.
2.3 The digital display is in 3-digit If you need more accurate indication, please
use more precise measuring instrument to calibrate it in outer circuit.
2.4 Cautions
2.4.1 The unit has perfect protection function, 5V output has reliable protection for
current - limiting and short circuit. The two adjustable outputs have current limiting
protection. As there is controlling circuit for regulating transistor’s power loss in
the circuit when short circuit occurs, power loss on large power transistor is not
very high, it can not cause any damage to the unit. But there is still power loss
when short circuit, in order to reduce aging and energy consumption, so this
situation should be find as soon as possible and turn off power then exclude the
faults.
2.4.2 After operating, put the unit in a dry place of good ventilation, and keep it
clean. If it is not in use for a long period, pull off the power supply plug for storage.
2.4.3 For maintenance input voltage must be cut off.
2.4.4 The faults may be caused by the improper operation or abnormal operating
ambient and component failure inside the unit. When the faults occur, the output
voltage maybe exceed max Rated output voltage. Take care when operation and
avoid unnecessary damage of load.
2.4.5 For safety operation, the 3-pin ground terminal of power cord must be
grounded securely.
