USVis Lamp life compared to CQXE

My question is: How we can explain the customer that they will need to change the lamp every one or two years when with the old instrument (ColorQuest XE) they changed the lamp after 5 or 6 years and as you know the customer will claim for that and we want to had the correct answer for it.

This customer has a UltraScan VIs not a ColorQuest XE. They CANNOT expect them to behave the same. The ColorQuest XE wavelength resolution was 2.34 nm/pixel,; the UltraScan Vis wavelength resolution is 1.64 nm/pixel - a 40% improvement. To achieve this improvement the polytube is larger to accommodate a bigger dual detector array. This requires more light so a larger amount of energy (30% more) is used to flash the lamp, i.e. 4.8 Joules compared to 3.75 joules. This results in decreased lamp life.

Cert of Traceability sent with USVis

Question : I have a customer looking for the certificate of traceability for their green tile. Do you have this on file?

Answer:

The White Tile was supplied with a certificate of traceability for its calibration relative to a perfect reflecting diffuser.

The Green tile was supplied with Read at Factory values, and is not a calibrated tile. It is a working reference tile.  It's assigned values occurred when the sensor was in a known good state of calibration. Its tile values are unique to the instrument that measured it.

Light Traps do not require calibration. They are assigned a value of 0.00 at all wavelengths.

Do the CQXE and USVis agree on APHA

Does the ColorQuest XE and the UltraScan Vis agree on APHA measurements?

The ColorQuest XE and UltraScan Vis share the same sphere, lamp, and collection optics. They differ in the optical bench size and range, detection and electronics. The UltraScan Vis can detect over the full range of Visible light, 360nm to 780nm compared to the ColorQuest XE which only detected light in the range of 400nm to 700nm.

The APHA index was developed by reading a standard test of actual APHA solutions on a ColorQuest XE and UltraScan Vis. This was done to insure the two instrument types had very close agreement in how they report APHA. We followed ASTM D5386 recommendation and used the YI E313 index as the basis for our polynomial fit. Each sensor has its own specific fit equation. The EasyMatch QC software determines which equation to use based on which instrument it is currently connected.

Haze Specification for USVis?

Is there a haze specification for the UltraScan Vis?

HunterLab does not have a published specification. If we did it would vary based on the Haze Value. Please note that Haze Standards are usually assigned by either ISO14782 or ASTM D1003 Procedure A compliant instruments. The UltraScan Vis is an ASTM D1003 Procedure B compliant instrument. Expect to see greater variance for Haze standards with value 5 and under than for Haze standards with value 10 and higher.

USVis USB to Serial Port Driver
The following steps might help to resolve these problem in connecting a computer to a HunterLab sensor. Note that the instrument beeps when one tries to install it, then the software returns a "sensor not found" error message. This is actually a good sign since it indicates that the computer port is working and that the cable is good, and the computer has found the USB device. If this occurs then we can immediately begin troubleshooting the port setup.
 
1.  Go to Start > Control Panel > System > Hardware > Device Manager, then expand the Ports (Comm & USB) branch of their computers device tree.
2.  You should see the USB to Serial Adapter port icon. If so, go to step 3. If not, then go to step 10.
3.  If the icon has a yellow warning icon, move the cursor to the icon and right click. Then click on Properties. The typical message at this point should be "This device is not working properly."
4.  Click on the Driver tab, then on the Update Driver box.
5.  Insert the EasyMatch QC installation diskette into the CD-Rom drive.
6.  Follow the instructions for the Install Driver Wizard.
7.  Windows should automatically find the driver FTDIBUS, install it and prompt you to click Finish.
8.  Before exiting the Device Manager go back to the Ports (Comm & USB) find the installed  USB to Serial Adapter. Right click, select Properties and record the Comm Port that the device is assigned to. Depending on how many devices are connected to the computer this could be a port number from 3 to 6 or higher.
9.  Exit the Control Panel, restart EasyMatch QC and attempt to install the sensor making sure to specify the correct communication port. Go to step 13.
10. If the USB to Serial Adapter is not located in the Port (Comm & USB) branch look in the Other Devices branch of the computers device tree.
11.  If the USB to Serial Adapter is located, shut off the Sensor, delete this file, Close the Device Manager, Restart the Sensor. Windows should find a new device installed.
12.  With the EasyMatch QC installation disc in the CD-rom drive follow the Windows Install New Hardware wizard. Go to step 7.
Note:  User must be logged onto the computer as an administrator.

 

My Sample Clamp does not seem to work. How can I troubleshoot the problem?

When a sample clamp does not appear to work properly, I would first examine the two components of the Sample Clamp assembly.

1) The Sample Clamp arm and actuator,

2) The Sample Clamp mounting channel.

Sample Clamp Arm- Exercise each button on the sample clamp.

- One button moves the "teeth" that allows the clamp to engage or release from the channel.  To test this function, remove sample clamp from channel.  Exercise the "in/out" button.  If teeth move, the clamp is probably ok.

- The Second button, allows the Sample Clamp arm to swing. If both of these function properly, I would move to the next assembly.

Sample Clamp mounting channel- The channel is mounted to the sensor base plate. To examine the channel, you first need to carefully move the sensor on its side so that you can view the channel. The channel functions to guide and position the Sample Clamp. Within the Sample Clamp channel is a spring loaded detent that catches the teeth of the Sample Clamp and allows the Clamp to lock at the desired position. The detent is the most common point of failure in the channel.

If the Sample Clamp slides freely in the channel and does not lock, check to ensure the detent is present and has not frozen in place or been broken by pulling the Sample Clamp out of the channel without first actuating the Sample Clamp buttons.

Most Sample Clamp repairs can be made by a qualified technician in the field or can be done by returning the Sample Clamp assembly to the factory.
