6-1 Using as a positive {+} stabilized power supply
1) S e t the L E D s a s s h o w n in the Figure 7. (Make sure that the
O U T P U T L E D is not lit.)
2) Turn the Rotary Encoder to set an arbitrary voltage value.
3) Press the A K E Y © and make sure that the A L E D lights up.
4) T u r n the Rotary Encoder to set an arbitrary current limit
value.
5) Press the O U T P U T K E Y ® to obtain the output value en-
tered from the positive ( + ) output terminal.
6-2 Using as a negative ( - ) output as the stabilized
power supply
1) S e t the L E D s a s s h o w n in the Figure 8. (Make sure that the
O U T P U T L E D is not lit.)
2) Turn the Rotary Encoder to set an arbitrary voltage value.
3) Press the A K E Y (6) and make sure that the A L E D lights up.
4) T u r n the Rotary Encoder to set an arbitrary current limit
value.
5) Press the O U T P U T K E Y @ to obtain the output value en-
tered from the negative ( + ) output terminal.
If the O U T P U T K E Y @ is pressed (ON), both positive and
negative output terminals supply a voltage and a current.
If the load short-circuits, or if the set current limit value
is reached, the circuit becomes overloaded and the out-
put voltage drops. T h e unit may be used a constanct-
current power source in this overloaded condition.
