Tricks and Tips

GENERAL TRICKS & TIPS:

Any job with the instrument should begin its visual review, verify that the optical path, white reference are clean, and all the mechanical parts are working properly. The temperature is important as well as the environment of fixture. Do not work with devices over-cooled or-heated.

If you want more precise measurements, see if you can improve anything from your site. Many times, especially in the case of many handheld scanning techniques can be improved by reducing the moving speed of the spectrophotometer. Some of the devices performs measurements e.g 100 times per second - the final result is averaged. So when you move the device too fast, we capture a smaller number of samples for averaging.

Many devices work differently depending on the driving software. Device manufacturers noting problems make software updates. New device working with older 3rd party software may be associated with maladjustment. For example , new calibration procedure can be available only in the newest version. Principal examples can be here i1 Pro 2, which requires the latest version of the SDK. On the market there is a lot of outdated software where calibration issue can be observed.

Some of the instruments has physical contact with the target. Before mounting Target check if mechanical adjustment can reduce scratching.

Good practice is to use the two interchangeably Targets. If one damage or dirty, the second allows for the diagnosis of the condition. Sometimes dirt or damage is difficult to see at first glance.

If you have e.g. three different instruments and three Targets make measurement of all Targets with each instrument to learn how yours instruments see differences between Targets.

In practice not be expected to perfect interchangeability of different devices, especially when derived from different manufacturers. Structural differences, different light sources, different aperture, different correction methods mean that, despite assurances to manufacturers data read will differ significantly. More statistical approach operating percentiles makes more sense as an assessment of the maximum error.

We noticed that a number of devices have problems with the correct reading of the black patch (1) in a repeatable and interchangeable between devices way.
