Hardware

  • PXIe-4080
  • PXI-4070

Driver

  • NI-DMM

Issue Details

When using the PXIe-407x and writing "auto" to the auto zero property, a read back of the same property returns "auto".
 
When using the PXIe-408x writing "auto" to the auto zero property, a read back of the same property returns whatever configuration that you are actually using (Once, On, Off).

Solution

The AutoZero feature functions the same on both the PXIe-407x and PXIe-408x devices. However, the property node more reflective of what the instrument is actually doing so instead of just returning "auto", it returns the actual setting the device uses.

Additional Information

The default autozero values for each device can be found below.
