Remote Control Operation - Extech Instruments DCP60 User Manual

Remote Control Operation
There are two methods for remotely controlling current and voltage adjustments. Current must be
controlled for both methods otherwise the unit will default to CC mode.
REMOTE CONTROL – METHOD 1: Using two external DC voltage sources

Check the output voltage range of the power supply by varying the external voltage source.
Short circuit the main output with 10AWG wire to check the CC setting on the display while
varying the external voltage source.
REMOTE CONTROL – METHOD 2: Using two 0 to 5K Ohm variable resistors

Check the output voltage range of the power supply by adjusting the 5Kohm variable resistor.
Short circuit the main output with 10AWG wire to check the CC setting on the display while
adjusting the variable resistor.
