Klein K-80

The Klein K-80 Colourimeter uses optics designed specifically for small screens, giving it an advantage in sensitivity over any other small screen probe, with very high operational speed, with excellent low light measurement capability.

  • ColourSpace Integration
  • Small & Large Screen
  • 10+mm Spot Size
  • Extremely Fast Response Time
  • 0.00009 to 10,000 cd/m2
  • Machined Aluminium & High Impact Plastic Construction

Overview

The Klein K-80 provides industry standard colourimetry analysis, as well as the capability to measure flicker, and can measure colour and flicker on TVs, LED backlit displays, CRTs, phones, tablets and more. While the Klein K-80 was designed with small displays in mind, it is an ideal all in one solution for display calibration and flicker analysis.

The Klein K-80 includes standard tripod mounting, and is constructed with machined aluminum and high impact plastic. The K-80’s auto ranging is solid state, and all probe readings are consistent regardless of the distance from probe to display/screen.

The K-80 can store up to 90 individual display matrices, enabling specific display technology to be perfectly matched.

The included Klein Chromasurf application enables user to generate their own matrices, and upload into the probe in addition to those provided as standard, or even from third parties.

Accessories

  • Metal carrying case
  • Contact measurement guard
  • Tripod

All accessories are included as standard.

Recalibration/Re-certification

The K-80 should be factory recalibrated/re-certified every year to two years, depending on usage and storage, or when obvious issue are found (after physical shock to the probe for example).
Cost is $300 USD, plus shipping ($600 USD for Rush recalibration).
Contact Klein to schedule recalibration/re-certification.

ColourSpace Integration

As with all probes, K-80 operation and function is controlled via the Probe Options menu, accessed via the Profiling window.

The K-80 has only two options that are directly associated with the probe - Probe Calibration, and probe Calibration Settings (Matrix pre-sets) - as well as generic probe settings, such as Extra Delay Time, Probe Matching, Probe Offset, etc.

Calibration Settings

Calibration Settings provides generic probe settings and preset Matrix options, as well as the Probe Calibration option.

Matrix Presets

The Drop-down menu provides access to the pre-set Matrices held within the K-80.
The Matrix presets match the probe to different display technologies - specifically the backlight/illumination spectral response.

Intelligent Integration

Intelligent Integration sets the nits level under which Intelligent Integration will be used.
This provides the best possible low-light measurements, without impacting reading speeds at luma levels above the set value, so maintaining overall speed of profiling.

Average Low Light

Average Low Light is a probe generic option, that averages multiple readings in low-light situations using an advanced algorithm built into ColourSpace. The algorithm varies based on the probe in use to provide the best possible results.
Average Low Light should not need to be used when Intelligent Integration is active.

Enable Visible Feedback

Enable Visible Feedback enables the inbuilt laser pointer, assisting with probe alignment when profiling screens from a distance.

Probe Calibration

The Probe Calibration button will save a dark current calibration reading, used to improve reading accuracy in low-lights.
Make sure the lens cap is fitted to cover the probe sensor.

Max Integration Time

Max Integration Time sets the maximum time taken for any given reading, in seconds.
The Klein default setting is 4 seconds.

Extra Delay Time

Extra Delay sets a delay time after the patch has changed before probe measurement starts, and can be set automatically via the Auto button, and manages signal path delays in the image pipeline.
When using the Auto option, Intelligent Integration & Average Low Light are normally not used.

Probe Matching

Probe Matching is used to match the K-80 Tristimulus to a Spectroradiometer, increasing the profile accuracy.

There are two different methods available for probe matching - 4 Colour Volumetric Matching (FCVM), and Multi-point Volumetric Matching (MPVM).
ColourSpace doesn't use the older, traditional, 4 Colour Matrix (FCMM) Method for probe matching, as the volumetric approach offers far greater probe matching accuracy.

Probe Offset

Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.
