Mode 2.  

Mode 1: before setting, press the controls to adjust the voltage and current levels. 

Mode 2: adjust directly, there is no need to press the controls.

• 

These two modes can be switched between by pressing the voltage adjustment 

control and the current adjustment control at the same time and holding for two 

seconds.

Front panel controls 

1.  Displays the setup value of the output current.

3.  Constant current mode.

4.  Constant voltage mode

5.  Over current protection active.

6.  Panel LOCK indicator.

7.  Adjustment knob for current.
