The relationship between output values of voltage and current on the same channel are
as follows.
• 1 V 4 mA
• 5 V 20 mA
Therefore, you can check the output accuracy of voltage and current simultaneously with
one setup.
Referring to the MW100 user’s manual for browser operation, or by using communication
commands, , set the output at power ON according to the table below. Power cycle the
MW100 main unit or equivalent, then measure the output on all channels.
