attribute to DC Voltage for the NI 4141.
Verifying Voltage Output and Measurement
Compare a set of voltages measured by the external DMM to both a set of voltage test points
requested by the NI 4141 and to the measured voltages reported by the NI 4141.
Refer to the following table as you complete the following steps.
