Hey guys, this is for Oppenheimer Dentistry. They want to run a test on their vatech pan machine. They are using this soft, called EzEval. Does someone knows how it works? -.- They click on start, and when they start to scan, process running disappear and nothing happens. Not really sure how it should be, or if they have to type some info on the fields there

If I'm not mistaken, this is not necessary if there's no tech issue? and this can be ran under a certified tech?

Tech B 2024-12-13 14:56

thats how I understood this. But we might be talking about 2 different processes - calibration and evaluation. Constancy test might be a daily routine helping to identify any issues before they start taking scans on patients Calibration is a more in depth process

Tech B 2024-12-13 14:57

maybe worth calling vatech and check with them?

Tech A 2024-12-13 14:58

Oh yes, It's not calibration, is constancy.. Ok I will check with them, thanks Sergey :)

Vatech had to log in and troubleshoot, they updated that software and ran some commands trough console on the machine

# Fix EzEval Constancy Test Process Running Issue on Vatech Pan Machine

## Problem
EzEval v1.6.2.0 constancy test software on a Vatech panoramic machine fails to complete the scanning process. When users click start and begin scanning, the "Process Running" status disappears and nothing happens. The interface shows empty/dark numeric readout fields for HU Value (Water, Air, Teflon, Result), Noise, and Uniformity (Top, Right, Bottom, Result) sections during the failed process. The console displays "[SPM_ARCT]" messages indicating the machine is ready to capture, but the test does not proceed normally.

## Resolution
Contact Vatech technical support for remote assistance. The vendor will need to:

1. Log into the system remotely
2. Update the EzEval software to the latest version
3. Run diagnostic commands through the machine's console to resolve the process execution issue

This issue requires vendor-level troubleshooting and cannot be resolved through standard user operations or local technical support.
