16 | ni.com | NI 5114 Calibration Procedure
9. Fetch a waveform from the device and perform a voltage average measurement using the
niScope Fetch Measurement (poly) VI. Select the Measurement Scalar DBL instance of the
VI. This value is the Measured Positive Voltage used in step 14.
10. Using the calibrator, output the Negative Input voltage listed in Table 6 that corresponds to
the vertical range used.
11. Wait 2,500 ms for the impedance matching and frequency of the calibrator to settle.
12. Initiate a waveform acquisition using the niScope Initiate Acquisition VI.
