Question: My customer has an old CQXE with the optional 420nm and 460nm UV filters. They were using Universal 4.10 and recently upgraded to EZMQC. They now get different b* values and noticed that when they insert the UV filter they cut-off point is different. How can they get the cut off point in EZMQC match the cut-off point in Universal.
They can't. Universal and EasyMatchQC report differently when the UVF mode to insert the 420nm and 460nm UV filter is used. There is no reason to make changes at this time since Universal has been obsolete since 2008 and the CQXE is also obsolete (since 2017) and will soon be out of Service Support. You can request a software CMR but I would imagine it would be expensive since the customer would have to pay for the full cost of the modification since the instrument involved is no longer manufactured.
Below is information on how the different software reports when the 420nm UV filter is inserted.
Universal 4.10 with CQXE ; Report 400nm = 0 ; report measured values from 410nm to 700nm
EZMQCv4.86 and lower with CQXE Report 400nm + 410nm = 0 report measured values from 420nm to 700nm
with USVIS Report 400nm + 410nm + 420nm = 0 report measured values from 430nm to 780nm
EZMQCv4.87 and higher with CQXE Report 400nm + 410nm = 0 report measured values from 420nm to 700nm
with USVIS Report the same as CQXE, 400nm + 410nm= 0, report measured values from 420 to 780nm
Question: Is the PM that was recently done on my Color Quest XE traceable to NIST?
During a Preventive Maintenance / Calibration Verification service done at your facility, no actual instrument calibration occurs. The only action that occurs is a tile set with values established as the population average for the CQXE family of instruments are measured. If your instrument measures this tile set within the stated tolerances than we state that it still in the same state as when it was actually calibrated at the factory. This is a verification of the calibration state of the sensor. The only NIST calibrated item associated with your instrument is the Instrument Standard Tile. The values assigned to this tile were derived by direct comparison to a tile that was traceable to NIST. Since your instrument when standardized with the NIST traceable tile was able to read Tile Set HCL407 with tolerance then we can state that the tile must still be in the same state as when it was last calibrated at HunterLab. If you require a new certificate of traceablity for your Instrument Standard Tile then you will need to return both your Color Quest XE and Instrument Standard Tile to HunterLab for calibration.
The ColorQuest XE Touch Screen model is calibrated for coordinate sensitivity at the factory. However, if you press a point and a different area is activated, a calibration procedure is provided to correct this.
To activate the touch screen calibration, touch the Exit, Close, or Return key (depending on the current screen) until the Applets Loaded screen is obtained.
There are two ways to access the Calibrate Touch Screen display:
- Press and hold the Macro/Read button on the instrument on the front of the sensor for about two seconds to obtain the Calibrate Touch Screen display.
- Turn the instrument OFF using the rocker switch at the back of the unit above the power cable. After 3 seconds, turn ON the sensor and when the ColorQuest XE splash screen appears, touch and release anywhere on the startup screen to obtain the Calibrate Touch Screen display.
Follow the prompts to touch each of the four corners of the screen in turn. You should use a pencil or other stylus to touch the screen for this calibration.
After all four corners are touched, “Calibration succeeded” is displayed and you may touch any part of the screen to exit. Press the Macro/Read key on the instrument to cancel the calibration procedure.
FAQ: "We instructed a customer to run Instrument DIAG, he gets the error message 'Error loading form, #13: Type mismatch'. What causes this message?"
These are generic Visual Basic or C++ error messages. These messages only relate to the last action the operator did prior to the message being displayed. So until I know what the last action was I cannot comment on what causes it to display.
For example, as a last action, did this error message occur before or after connecting?
If this message occurred with the ColorQuest XE when running CQXEDiag software, his means current version CQXEDiag130B.msi will work with all sensors, If using a prior version such as CQXEDiag120 then it would only connect to sensor serial number CQX3678 or lower. Firmware or board changes that occurred from CQX3679 and newer or even an older sensor that recieved a newer board, such as an SPSP would require the newer Diagnostics to communicate.
