Software Requirements
Calibrating the FD-11603 requires the installation of NI-DAQmx on the calibration system. NI
recommends using the latest NI-DAQmx driver. Earliest driver support version for calibrating
the FD-11603 is listed in the following table.
Driver
NI-DAQmx
You can download NI-DAQmx from ni.com/downloads. NI-DAQmx supports many
programming languages, including LabVIEW, LabWindows
Basic .NET. When you install NI-DAQmx, you only need to install support for the application
software that you intend to use.

NI-DAQmx C Reference Help—Provides reference information for NI-DAQmx C functions and NI-DAQmx C properties. Test Equipment The following table lists the equipment required for calibrating your FD-11603. If you do not have the recommended instruments, use the minimum requirements to select substitute equipment. -
Page 3: Test Conditions
22 AWG signal wires Test Conditions The following setup and environmental conditions are required to ensure the FD-11603 meets published specifications: • Keep connections to the device as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements. -
Page 4: Initial Setup
Initial Setup Complete the following steps to set up the FieldDAQ device. Install the software and NI-DAQmx driver as outlined in the FD-11603 Quick Start. Note You must install NI-DAQmx 18.5 or later for device calibration support. Set up the FieldDAQ device as outlined in the FD-11603 Quick Start. - Page 5 0.00105 Positive Full Scale 10.0 9.99525 10.00475 The test limits in this table are derived using the values listed in Accuracy Under Calibration Conditions.
