3.Quick Review If it is found that there is damage to the appearance of the instrument, or the instrument can not work normally, or fails in the performance test, please get in touch with our distributor responsible for this business or our local offices. If there is damage to the instrument caused by the transportation, please keep the package.
3.Quick Review The following steps check basic current functions with a short across the power supply's output: (1) Connect a short across (+) and (-) output terminals with an insulated test lead on this channel. Use a wire size sufficient to handle the maximum current. (2) Set the output voltage to the maximum rating on this channel. (3) Turn on the channel output. Ensure the channel you used is in Constant Current output mode.
4.Panel Operation 4. Panel Operation 4.1 Turn On/Off the Channel Output Press the On/Off key to turn on/off the channel; 4.2 Set the Output Voltage/Current In the channel setting area, press the V / I key to move the blue cursor between different positions of the voltage/current value. After pressing the output voltage/current setting value, turn the knob to change the value of the current cursor, and press the knob or press the V / I key to move the cursor.
