Frequently Asked Question


Color & Appearance


General

What should I include when sending my unit in for service?

Please send in all masks, cables, AC adapters, the calibration plate and any other accessories that need to be tested or calibrated to the unit.

Do I need to calibrate my unit everyday before I perform measurements?

Yes. You should calibrate to your standard before you perform your measurements. Most units will ask you to calibrate if you have not already.

How often do I need to send in my unit for calibration?

Konica Minolta suggests that you send in your unit for calibration yearly due to use of unit; degradation of white plate, etc.

What is the difference between Illuminant C and D65?

Both are standard daylight illuminants; C is the average of north sky daylight and D65 is the most commonly used illuminant representing noon daylight. Most of our units default setting is C.

What is a Colorimeter?

A colorimeter is an instrument used to measure light reflected or transmitted by a specimen. There are two general types of colorimeters commonly used – visit our website to learn more about functions of a colorimeter.

What is a Tristimulus Colorimeter?

A Tristimulus Colorimeter is an instrument used to measure quantities which can be used to obtain an approximation of tristimulus values. They are used only for measuring the color difference between two similar, nonmetameric samples. Visit our website to learn more about the Tristimulus colorimeter.

If my unit came with a white calibration plate, do I need to send that in when I send my unit in for calibration?

Yes. Always send in whatever calibration plate that is associated with the unit. Degradation of the calibration plate causes the values to change and you want the most current values for that particular plate.

CM-3600d Bench Top Spectrophotometer

I receive an error when trying to load unit drivers and calibration data for my CM-3600d. How can I load my drivers and calibration data from the CD when using OnColor?

The CD has read only files that are not recognized by OnColor. You must copy the files from the CD into the Cm3600 folder in the OnColor folder. The default location is C:\Program Files\CyberChrome\OnColor\Cm3600.

Recently I have been getting an “Error 11” occasionally on my CM-3600d. Do I need to send the unit in for service?

During the summer months when the temperature and humidity are high, it is possible that the temperature and humidity levels of the unit can be exceeded, especially in a manufacturing environment. Move the unit to a dryer, cooler location and retest. If the error persists, please send the unit in for service.

How I load CM-3600d data into SpectraMagic? FOR LOADING 3600 CALIBRATION DATA AND INPUT DRIVERS FOR SPECTRAMAGICNX AFTER SERVICE.

Please follow these instructions if the 3600d has previously been connected to the computer with SpectraMagic NX:

  • Right click on SpectraMagic NX software icon, choose properties from menu.
  • Click “Find Target” button. In the window that opens up look for the folder named CM3600d.
  • Open the CM3600d folder and sort the files by name.
  • There are about 16 files that begin with DLL. DO NOT delete those files.
  • Only delete the files that begin with the serial number of your CM-3600d and the files that have the serial number of the white calibration plate. There should be about 29 files altogether.
  • Turn CM-3600d on. Open software. The software will ask for the unit drivers. Navigate to the CD and load the unit drivers.
  • After the unit drivers are loaded the software will ask for the calibration data. Load the calibration data off of the CD.

CM-2600d Portable Spectrophotometer

How often should I send in my CM-2600d for service?

Konica Minolta recommends sending the unit in once a year for calibration.

CR-400 Colorimeter

Why can’t my DP-400 communicate with my CR-400?

Make sure that the CR-400 is not in PC Mode. To take the CR-400 out of PC Mode, press the ESC button on the Measuring Head.

What is the different between CR-400 and CR-410?

The different between a CR-400 and CR-410 is mainly on the measurement area. CR-400 measurement area is 8mm in diameter whereas CR-410 measurement area is 50mm in diameter.

Radiometric


General

What is the level of tolerance for my light meter?

Every light meter has a difference tolerance level. Please consult your manual or the certificate of conformance supplied with your unit for yours.

Is there any conversion methods for converting footcandela (fcd) values to lux (lx) and vice versa?

Yes there is but most of the light meters can measure in both lx and fcd. The conversion formula is as follows: 1 fcd = 10.76 lx.

What is the best light meter to use for my company?

After speaking with one of our highly capable radiometric salespeople, you will be able to determine what light meter should be utilized for your company.

Can I download my measurement data and if so; how easy is it?

Each unit has it own capabilities so consulting your owners manual might help. If you are still experiencing difficulty, our Technical support engineers will be glad to guide you thru the process.

What light source in Konica Minolta using to calibrate my light meter and is there any way to recreate that myself and calibrate it myself?

We use a N.I.S.T. (National Institute of Standards and Technology) certified tungsten filament lamp to calibrate our light meters and only a Konica Minolta certified Service center can calibrate our light meter.

T-10A/MA

How do I set my T-10A/MA from lx to fcd?

Power “OFF” the meter. Remove body battery cover and the batteries. Switch button from lx to fcd.
