FAQ: “I received a upgrade of EasyMatch QC for an old CQ-45/0 LAV. I loaded the EasyMatch QC program from the CD and then it prompts me for a calibration file when I select Sensor/Install-Configure and load a ColorQuest 45/0 sensor.
I only received and EasyMatch QC installation CD and hardware key where is the calibration file? The ColorQuest 45/0 LAV we are working with has a serial number “CQ49200”. Can you help here?”
It is not typical these days to work with older legacy ColorQuest instruments where the calibration came on a file rather than our current practice with ColorQuest XE sensors of storing the calibration data for the instrument standards on a memory chip on the CQXE sensor.
Typically, the system came with a calibration file, “CQXXXXX.cal “ (CQ49200.cal in this case where "49200" is part of the "C49200" serial number of the instrument), on a diskette. Usually this calibration diskette is kept in the Standards Box. If this has been misplaced, contact HunterLab.
Here are the steps. Note that while a CQ 45/0 LAV sensor is used as an example here, this procedure also applies to ColorQuest II diffuse d/8 sphere and ColorQuest 45/0 Regular sensors.
- If the PC does not have a floppy drive, save the file to a flash disk and take it to the PC.
- Install EasyMatch QC from the CD.
- Plug the EZMQC hardware key into one of the USB ports on the PC.
- Copy the file “CQXXXXX.cal” to c:\HunterLab\EasyMatchQC\Jobs.
- Enter EZMQC and go to Sensor/Install-Configure to install a “ColorQuest 45/0” with the large 3.75-in area of view.
- You will be prompted for a file in the form “CQXXXXX.cal” and it will first look in the c:\HunterLab\EasyMatchQC\Jobs folder, but you can point it to any location where this calibration file is.
- After the sensor is installed, standardize normally.
- Once installed correctly (IQ complete), the sensor and serial number will display at the bottom of the screen.
As a further OQ Operation Qualification, run Sensor/Diagnostics for:
- Short Term Repeatability on the White Tile.
- Long Term Repeatability on the Green Tile Test.
If both tests PASS, proceed to measure samples.
