As-Found and As-Left Limits
The as-found limits are the published specifications for the NI 5170R. NI uses these limits to
determine whether the NI 5170R meets the device specifications when it is received for
calibration. Use the as-found limits during initial verification.
The as-left calibration limits are equal to the published NI specifications for the NI 5170R, less
guard bands for measurement uncertainty, temperature drift, and drift over time. NI uses these
limits to reduce the probability that the instrument will be outside the published specification
limits at the end of the calibration cycle. Use the as-left limits when performing verification
after adjustment.
Measurement Uncertainty
Measurement uncertainty was calculated in accordance with the method described in ISO
GUM (Guide to the Expression of Uncertainty in Measurement), for a confidence level of
95%. The expressed uncertainty is based on the recommended measurement methodology,
standards, metrology best practices and environmental conditions of the National Instruments
laboratory. It should be considered as a guideline for the level of measurement uncertainty that
can be achieved using the recommended method. It is not a replacement for the user
uncertainty analysis that takes into consideration the conditions and practices of the individual
user.
Calibration Overview
Install the device and configure it in Measurement & Automation Explorer (MAX) before
calibrating.
Calibration includes the following steps:
