Jeti 2511
The Jeti 2511 is a compact Spectrometer that delivers high quality results, with very accurate measurement capabilities on all display devices.
- ColourSpace INF/XPT/PRO & HTX/HTP & DPS
- 4.5nm Spectral Bandwidth (2nm HiRes version)
- 0.2 to 140,000 cd/m2
- 4.3” capacitive touch display
- Laser Pointer Alignment
Overview
The Jeti spectraval 2511 is fast and highly sensitive, covering the wavelength range from 350 to 780nm, and includes an internal target spot laser for alignment. A piezo-electric shutter provides dark signal compensation.
Unlike the spectraval 2501, the spectraval 2511 also includes an in-built display that allows for direct measurement use.
The spectraval 2511 is provided without a Cosine Diffuser as standard, as for display calibration use this is unused. The diffuser can be specified when ordering if required.

Recalibration/Re-certification
The spectraval 2511 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).
Contact Jeti to schedule recalibration/re-certification.

spectraval 2511
ColourSpace Integration
As with all probes, operation and function is controlled via the Probe Options menu, accessed via the Profiling window, with the left-hand side of the menu providing generic probes settings, and the right-hand side settings specific to the spectraval 2511.
2511 Settings
The Settings options provide specific Jeti 1211 configurations. Full details for all options can be found within Jeti's own documentation.
Sync Frequency
Sync Frequency defines the sync frequency of the probe, with Auto being the default, although Manual can be used if the refresh rate of the display is known.
(If the Jeti shows an adoption error, the frequency will need to be manually set to the video frame-rate.)
Additional Settings
Additional settings settings available with supported probes.
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.
Enable Visible Feedback
Enable Visible Feedback enables the inbuilt laser pointer, assisting with probe alignment when profiling screens from a distance.
Probe Adjustments
Probe Adjustments are generic probes settings, with consistent operation regardless of the probe in use.
Configure Matching
Probe Matching is really unnecessary with the Jeti, as it is a Spectrometer.
The options is provided on a Why Not basis...
Offset
Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.
Extra Delay
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.
Note: Some probe/settings/display combinations will not work accurately with the Auto function
