The LED(LCD) display is in three digits (analog meter is 2.5 class). To get more accurate measuring
value, you should calibrate by external circuit with precision measuring instrument.

CAUTION
3.1 This unit has excellent protection function, 5V output has reliable protection for current-limit and
short. The two adjustable outputs have current-limit protection. As there is controlling circuit for
regulating transistor’s power loss in the circuit, when short-circuit occurs, the power loss on large
power transistors is not very high, it can’t 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
found as soon as possible and turn off power, then exclude the faults.
3.2 When operating is finished, put it 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.
3.3
For maintenance, input voltage must be cut off.
