Overview
This code demonstrates how to access the various shunt calibration resistors available with the PXIe-4339 connected to the RM-4339 accessory.
Description
The RM-4339 gives users access to a variety of shunt calibration resistors. In quarter bridge mode, users can use either the 50 kOhm or 100 kOhm SCB resistors built in to the RM-4339. In half or full bridge mode, the user can either use the built-in 100 kOhm SCA resistor or a user-provided resistor of any value with the SCAL-4339 accessory.
Steps to Implement or Execute Code
Attach a bridge-based sensor to the RM-4339 and then run the VI. If you select to use a user-provided SCA resistor for shunt calibration of a half or full bridge sensor, you will need to use the SCAL-4339 accessory.
Requirements
Software
- LabVIEW 2011 SP1 or later with NI-DAQmx 14.5 or later
- If running in a Real-Time context, you will need the LabVIEW Real-Time Module 2011 SP1 or later
Hardware
- NI PXIe-4339 with the NI RM-4339 accessory and (optional) SCAL-4339 accessory
- External precision DC calibration source
