2. Set the niDCPower Sense property or
NIDCPOWER_ATTR_SENSE
attribute to Remote.
3. Set the niDCPower Output Function property or NIDCPOWER_OUTPUT_FUNCTION
attribute to DC Current for the NI 4141.
Verifying Current Remote Sense Accuracy
Use the NI 4141 in constant current mode with a test circuit to simulate the voltage drop
between the device and a load.
Measure all of the specified resistors using the DMM before you connect equipment. Record
the values.
Refer to the following table as you complete the following steps.
