This document describes the procedure for verifying and adjusting a
National Instruments 6110/6111/6115/6120 data acquisition (DAQ)
device. This document contains four main sections:
• Introduction —This section tells you what calibration is, why you
should calibrate devices, and how often you should calibrate.
• Equipment and Other Test Requirements —This section describes
what you must do before calibrating the device, including an overview
of the test equipment, software, calibration functions, and environment
needed for calibration.
• Calibration Process —This section provides step-by-step instructions
for verifying and calibrating your device.
• NI 6110/6111/6115/6120 Specifications —This section provides
specification tables for the NI 6110/6111/6115/6120.
This document is intended for metrology labs. It does not cover
programming technique or compiler configuration because of the number
of programming languages and styles you can use to calibrate the device.
However, NI-DAQ has many online help files that contain
compiler-specific instructions and function explanations. You can install
these help files when you install NI-DAQ.
Introduction
What Is Calibration?
Calibration is a set of operations that compares the values indicated by a
measuring instrument or measuring system to the corresponding values
realized by external standards. The result of a calibration can be used to
determine the measurement error and can correct for it in the adjustment
process.
The calibration process consists of verifying, adjusting, and reverifying a
device. During verification, you compare the measured performance to an
