(2) Voltage Indication
(3) Fine (10 Turn) adjustment of Voltage
(4) Up/Down Adjustment of Current
(5) Power On/Off
(6) Negative Output Terminal
(7) Positive Output Terminal
(8) Ground Connection
(9) Constant Current Indicator
(10) Constant Current Switch
(11) External Power Output Connection
The unit has one output display. The display has 2 readings. One is Voltage and the second is Current.
The Voltage is 0-30 Volts with 0-3Amps. This unit has a fan that turns on when the temperature reaches
140DegF or 60DegC. It takes a standard 110VAC input only and is fuse protected.
2.2 Operating Procedure
2.2.1 For constant Voltage mode make sure #10 is depressed and the LED #9 is off.
By rotating the knob of #3 to the right increases the voltage output and rotating it to the left decreases the
voltage output.
3. Attention:
3.1 The mains power must be switched off before servicing and servicing should be referred to a qualified
person.
3.2 The unit should be stored in a dry and well ventilated place and the power cord removed for long
periods.
4. Accessories:
4.1 Power cord ————— one piece
4.2 Instruction Manual—— one piece
4.3 1 set of Banana plug to Alligator Clips
4.4 1 set of hook up wires for external hook up.
