•
Load is connected as shown above.
•
Switch the unit on.
•
Output current and voltage will be indicated by LED.
•
You should adjust the load to have the desired value.
•
Switch the unit on.
•
Turn the adjustments (9) and (10) clockwise to the end, and the (4)
anti-clockwise to the end.
•
Then connect your load.
•
Turn the current-adjustment (4) to get desired current.
•
The LED (2) is on and the LED (3) is off.
•
The current-adjustment (4) must be set to its maximum value.
•
Switch on power and adjust the voltage (9) and (10).
•
The LED (3) is on and the LED (2) is off.
•
To adjust the current limit : switch the unit off and short-circuit outputs
5 (+) and 7 (-).
•
Switch on again and turn the current-adjustment (4) to get desired
desired limit current.
•
Switch the unit off. Enlevez le court-circuit and connect the load.
•
Switch on again.
To get more accurate measuring value, you should calibrate by
external circuit with precision measuring instrument.
•
This unit has excellent current-limit protection. If short-circuit
occurs, the output current is limited.
•
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.
•
Store the instrument in a dry, clean and ventilated place.
•
Disconnect the unit if it should remain unused for quite a long
time.
