Connection
Wire the units in the same manner as in the “Output at Power ON Check.”
Settings
<MX100>
Set one channel at a time, setting the output of channels not under test to 0 V.
When using the MX100/DARWIN API for settings, enter settings that are equivalent to
the following.
Item Setting Description/Notes
Enable/disable Enabled
Action User output
Voltage/current Voltage Not relevant when using the API
Span Need not specify -10–10 V is acceptable.
Output upon power ON Preset value Sets the power ON operation as the preset.
Output upon error Preset value Sets the output upon error as the preset.
Preset value +0 V Sets +0 V as the preset value.
Other Not required
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.
<MW100>
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.
