APEX WAVES FD-11613 Temperature Input Device for FieldDAQ User Manual

Software Requirements

Calibrating the FD-11613 or FD-11614 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-11613 or FD-11614 is listed in the following table.

Table 1. FD-11613/11614 Driver Support

Driver	Earliest Version Support for Device Calibration
NI-DAQmx	18.1

You can download NI-DAQmx from ni.com/downloads. NI-DAQmx supports many programming languages, including LabVIEW, LabWindows™ /CVI™ , C/C++, C#, and Visual Basic .NET. When you install NI-DAQmx, you only need to install support for the application software that you intend to use.

Test Conditions

The following setup and environmental conditions are required to ensure the FD-11613/11614 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.
Verify that all connections to the device are secure.
Use shielded copper wire for all cable connections to the device. Use twisted-pairs wire to eliminate noise and thermal offsets.
Maintain an ambient temperature of 23 ±5 °C. The device temperature will be greater than the ambient temperature.
Keep relative humidity below 80%.
Allow a warm-up time of at least 10 minutes to ensure that the FieldDAQ device measurement circuitry is at a stable operating temperature.

Calibration Procedure

The calibration process includes the following steps:

Initial Setup
Verification
Adjustment
EEPROM Update
Reverification

Initial Setup
Complete the following steps to set up the FieldDAQ device.

Install the software and NI-DAQmx driver as outlined in the FD-11613/11614 Quick Start.
Note You must install NI-DAQmx 18.1 or later for device calibration support.
Set up the FieldDAQ device as outlined in the FD-11613/11614 Quick Start.
Configure the FieldDAQ device in Measurement & Automation Explorer (NI MAX) as outlined in the FD-11613/11614 Quick Start.
If the FieldDAQ device is not reserved automatically, select the device and click the Reserve Network Device button. Refer to Reserving the Device in MAX for more information.
Self-test your device in MAX by expanding Devices and Interfaces »Network Devices , right-clicking your FieldDAQ device, and selecting Self-Test. Self-test performs a brief test to determine successful device installation. When the self-test finishes, a message indicates successful verification or if an error occurred. If an error occurs, refer to ni.com/support/daqmx.

Reserving the Device in MAX
When the FieldDAQ device is connected to a network, multiple users can access the device. To perform any DAQ functionality on the device, including reset and self-test, you must reserve the device in MAX. In MAX, an unreserved device or device reserved by another host appears with an X and a reserved device appears as dark grey. Only one user at a time can reserve the Field DAQ device. If the device was not reserved automatically after it was added (Add Device), you can reserve the device in MAX by expanding Devices and Interfaces»Network Devices, selecting the device, and clicking the Reserve Network Device button. The Override Reservation dialog box opens when you attempt to explicitly reserve a device. Agreeing to override the reservation forces the Field DAQ device to be reserved by the current user.

Verification
The following performance verification procedures describe the sequence of operation and test points required to verify the FieldDAQ device. The verification procedures assume that adequate traceable uncertainties are available for the calibration references. Complete the following procedure to determine the As-Found status of the FieldDAQ device.

Connect the calibrator to Bank 1 of the FieldDAQ device, as shown in the following figure.
Figure 1. Bank 1 Voltage Channel Verification Connections
On the calibrator, lock the voltage range to 3.3 V to reduce loading error.
a. Set the output voltage to 2.0 V.
b. Press the 3.3 V auto button to lock the 3.3 V range.
Set the calibrator output to a Test Point value indicated in the following table.
