FAQ

How will I know when a new firmware version is available?

It is not necessary to update your firmware unless instructed to do so by LDARtools Support.

 

New firmware versions are available on the Firmware tab of the phxApp.

Do I need to calibrate my phx42 after I update the firmware?

Yes. Loading new firmware will clear you calibration records for that day. Avoid updating the firmware unless you have already pulled your monitoring data and performed drifts for the day.
