connected with an external high precision measuring instrument.
(8) The negative terminal of output, to be connected with the negative
end of the load----Normally for test, examine and repair, or to be
connected with an external high precision measuring instrument.
(9) The positive terminal of output, to be connected with the positive end
of the load.
(10) The negative terminal of output, to be connected with the negative
end of the load.
(11) Power Switch. Flip up to turn the power “ON”; flip down to turn the
power “OFF”.
2.2 Load Connection
Connect the positive end of the load to the positive terminal (#7) or
(#10) and the negative end of the load to the negative terminal
(#9). When the power is turned on, the LED displays the output
current value and displays the output voltage value. If the current is
past the rated range and the CC (#5) indicator is lit, then there is an
overload or short-circuit. Please adjust the load to have the unit
recover from this state.
2.3 To use as a Constant Current Power Source (CC)
After turning on the power, turn the Voltage Regulation
Adjustment Knob (#4) clockwise to maximum, and turn the
Current Regulation Adjustment Knob (#3) counterclockwise to
minimum, then connect the load and turn the Current Regulation
Adjustment Knob (#3) clockwise until the output current gets to
the desired current setting.
2.4 To use the unit as a Voltage Power Source (CV)
Turn the Current Regulation Adjustment Knob (#3) clockwise to
the maximum. The current-limit protection point can be set
arbitrarily at the same time and the method is as follows: turn on
the power supply, connect the unit with an appropriate load of
variable resistance and adjust the resistance to make the output
current equal to the value at the current-limit protection point, then
