ColorQuest XT Touch Screen has lost sensitivity

FAQ: “…The CQXT Touch Screen is working but, bout 80 percent of the time, your first press will work.”

Over time, there can be a buildup of skin oils from pressing and this can de-sensitive the CQXT touch screen.

Dampen a Kim Wipe with isopropyl alcohol or similar lens cleaner and gently wipe the screen. Repeat this several times until all skin oils are removed from the screen.

Re-calibrate the touch screen using this procedure - https://support.hunterlab.com/hc/en-us/articles/206620506-How-to-calibrate-the-Touch-Screen-on-a-ColorQuest-XT

If you run this touchscreen calibration procedure and the screen still does not have good sensitivity, the Touchscreen Overlay (HL Part # D02-1014-800) may need to be replaced. This is a film that covers the LCD screen and is connected to the processor board via a ribbon cable.

With care, it is possible for you to replace this part onsite. Or, contact HunterLab Service for screen replacement options.

Is CQXT calibration NIST traceable?

Question : Is CQXT calibration NIST traceable?

Answer: Depending on the exact phrasing of the question the answer changes. Calibration of a CQXT is twofold. There is a Photometric Calibration where the instrument is flashed with no specimen or a blank specimen in the light path and the resultant measurement is scaled to represent 100% T at all reported wavelengths. NIST traceability does not apply since technically there is nothing in light path. The CQXT is subjected to a Wavelength Calibration at the factory using the emission lines from a Hg and a HeNe laser. Since these gases are constants of nature NIST considers their emissions to be unchanging. So NIST has no involvement with the photometric calibration of the sensor. The NIST Atomic Spectra Database Lines website contains a list of the known emission lines of these gases.

HunterLab uses colored glass filters to perform system validation. These filters represent the population average for a group of CQXT instruments in a known good Wavelength Calibration status. This population average has no direct comparison to NIST measurements. If a customer CQXT cannot measure the colored glass filters to within the HunterLab specified tolerances then the instrument will need to have its Wavelength Calibration reassigned.

ColorQuest XT Power Indicators

How do I know if my CQXT is getting power?

The ColorQuest XT (CQXT) has two power light indicators. The first is on the instrument itself and is located in the upper left hand corner of the front of the instrument. The second indicator light can be found on the touch screen in the upper left as well. Both of these power indicator lights must be green, if either of them are not it indicates that power is not reaching the component. Can you tell me if either of these have the power indicator light on or neither? The main power switch is located at the back of the instrument above the power cord.

How to calibrate the Touch Screen on a ColorQuest XT

The ColorQuest XT’s touch screen 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:

  1. 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.
  2. 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 XT 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.

ColorQuest XT data output options

FAQ: "Is there any way for the ColorQuest XT to export color readings to another computer?"

The ColorQuest XT Applet Display does not store data records. The sensor makes and displays measurements on the dedicated display. By pressing the "PRINT" key the contents of the display screen can be sent to a serial hardcopy printer connected using a serial cable plugged into the serial "PRINT" connector on the back of the display.

What is sent to the serial printer is an ASCII dump of the screen contents.

Here are two options for CQXT data export:

  1. The same functionality as printing can be used to get data out of the unit. Just run a serial cable from the "PRINT" female serial connector on the back of the display to a PC. When "Print" is selected on the screen, ASCII measurement data on the screen is sent out the Serial COM port on the back of the display to a PC where customer data collection software can collect the string and parse it into a file.
  2. Another alternative is to run the CQXT using HunterLab EasyMatch QC software. The software effectively runs the sensor bypassing the display  and all measurement data is collected in EasyMatch QC for Options/ASCII Export.  
ColorQuest XT Touch Screen has dead spots

First check the CQXT Touchscreen calibration as described in more detail at https://support.hunterlab.com/hc/en-us/articles/206620506-How-to-calibrate-the-Touch-Screen-on-a-ColorQuest-XT

Power off the sensor, then power back on, as soon as the logo appears in the center of the screen, touch the logo.

This should bring you to the calibration screen where you will be asked to touch specific points around the perimeter and middle of the screen.

If you run this touchscreen calibration procedure and the screen still has dead spots then you may need to replace the Touchscreen Overlay. This is a film that covers the LCD screen and is connected to the processor board via a ribbon cable.

 The part number for this is D02-1014-800. Contact HunterLab for pricing and installation instructions.

Alternatively you can request an SRO to have the sensor returned to the HunterLab Service for repair.

Standard Applets for ColorQuest XE with Touch Display

ColorQuest XE with Touch Display is a dedicated transmission color instrument for transparent solids and liquids, and is able to measure in transmission and reflectance with two areas of sample view, UV calibration and transmission haze. The CQXE with Touch Display is an all-around instrument with a dedicated processor.
