2.2. Operation：
1、Adjust control knobs (3.) and (4.) clockwise to maximum position
before power supply is powered on, once switch on the power
supply, and adjust knobs (5.) and (6.) to preferred voltage values;
firstly to adjust (6.), the coarse tuning knob, to the requested value,
and adjust(5.), the fine tuning knob up to precise value.
2、Connect the equipment under test to the power supply, (12.) is
connected to the positive polarity input of the equipment and(10.)
is connected to the negative polarity input of the equipment. After
powered on, (2.) displayed current output value, (1.) displayed
voltage output value. If overload, the (7) LED lighted up and (2)
displayed over rated value, and then, reset the equipment will be
needed.
3、Switch on the power supply, at the same time turning knobs (5.)
and (6.) clockwise to maximum value, knobs (3.) and (4.) counter
clockwise to minimum value, and then connected with equipment,
clockwise turning knobs (3.) and (4.) to the requested stable
current value.
4、Switch on the power supply and turning knobs (3.) and (4.) to the
maximum value, which can arbitrarilyset the current limit protection
point, the methodis as below; Switch on the power supply, with the
appropriate variable load and adjust the load resistance, so that
the output current is equal to the current limit protection point, and
then turning knob (3.) and (4.) respectively to let flow indicator as
critical state, then, the current limit protection was set up.
5、The LED display of power supply is 3-1/2, if need the more
precision value, it will be necessary to be calibrated by a precision
measuring instrument in the external circuit.
