Measurement View

The Measurement View is the default when starting ColorMeter.

Measurement View
A -The top line shows the instrument type if connected, and its current status.

B - The drop-down menu below this shows the current measurement mode and allows the mode to be changed. Instruments that can be mechanically configured in different ways, such as the ColorMunki Spectrometer or Eye-One Display Pro will change the list of available modes when they are re-configured. The last selected measurement mode will be remembered for each instrument configuration. Note that the Emission and Ambient Flash measurement modes are intended to measure photographic flash light Luminance and Illuminance respectively, and are designed to exclude non-flash lighting contributions.

C - The next drop-down menu shows the current display calibration mode if applicable to the instrument and measurement mode. Colorimeters typically have different calibration settings for different types of display technologies, and this menu allows selecting the appropriate calibration. This menu also allows choosing between refresh display measurement modes and non-refresh modes for instruments that make this distinction. If display calibration is not relevant for a particular instrument or its measurement mode, then the menu will be blank. Installed CCMX (Color Correction Matrix) and CCSS (Color Correction Spectral Sample) files will appear in this menu.

D - Below the two menu is the Readout area. This consists of a vertical list of individual Readouts. The list is scrollable when it exceeds the available screen space.

Tap a Readout to add new Readouts or to configure them

Slide or fling a Readout left and then up or down to re-arrange them. They can also be arranged from the Readout Configuration Dialog.

Slide or fling a Readout right to delete it. They can also be deleted from the Readout Configuration Dialog.

Double tap (or two finger tap) a Readout to set a value (color calculator operation, or setting reference values). Note that not all readout types are settable, since things like CRI don't contain enough information to completely define a color value, and an error dialog will indicate this.

Long press a Readout to trigger the system text selection & copy to Clipboard.
Readouts with a single line of output will have the numeric information selected and ready to copy to the clipboard. Other readout types will have the output section touched selected. Touching "Select All" in the Text Selection Action Menu will select all readout sections, and format the string with extra information such as the Readout source, Colorspace, Units, Date measurement was taken etc. i.e.:
 

Normal Readout, default selection: "95.35 -0.57 2.00"

Normal Readout, Select All:
"Measurement  L*a*b*:  95.35  -0.57  2.00  ∆E  Oct 15 2014 1:18:05 PM"

Exposure Calculator, default selection: "f/0.9"

Exposure Calculator, Select All: "Measurement: Shutter:500 Aperture:f/0.9 ISO:400 Adjustment:0.0 Oct 15 2014 1:18:05 PM"

Named Color Swatch, default selection:     
"Warm Yellow 1234"

Named Color Swatch, Select All: "Warm Yellow 1234 (2.5 ∆E 2K) Oct 15 2014 1:18:05 PM"

To the right of the readouts are buttons to switch to other views:

The top right hand button - E - switches to the Chromaticity Graph view.
The next right hand button - F - switches to the Spectral Graph view.
The last right hand button -  G - opens the Video Test Patch Generator Dialog  dialog, for selecting the ChromeCast that will display the test patches, configuring the location, size and background of the test patch, as well as offering a menu of pre-set Video test cards that can be displayed.

At the bottom of the view is a row of buttons:

H - The leftmost button stores the last measurement in one of the 8 Primary-Color References ("Sources" or "Registers"). This auto switches to the most likely color given the measurement value, but can be overridden by touching the selector adjacent to the button Reference Color Selector and then touching the primary color to store into. Touch somewhere else on the screen to avoid storing the measurement. The Primary Color references are used for a variety of purposes, such as helping to computing some Readout values, as well as providing a means to plot a color gamut. It's also possible to use them as general references. (Note though that all Readouts that compute differences do so between their Source Register and the Reference Register.)

I - The middle left button stores the last measurement in the Main Reference. This is the value used for most of the comparative Readouts such as delta E's, Reading Delta's, RGB Adjustment Reading etc.

J - The middle right button starts a measurement, or alternately the instrument button (if it has one) can be used to start a measurement.
A long press of this button brings up the Measurement Action Dialog, where you can change the measurement action from single to continuous measurement. When in continuous mode, this button is used to start and stop measurements. To make a flash measurement in Flash measurement mode, press and hold the instrument button, trigger the flash, and then release the instrument button.

K- The rightmost button has two related functions. A single press toggles the state of the current measurement between Keep Green Tick, and Discard Red Cross. Discarded measurements are not deleted, but they will be ignored in the default Measurement Log navigation, and won't be exported. A long press toggles the Measurement Log Navigation controls Visibility.


At the very top right is the Android menu items:

L- CONFIG brings up the Configuration Menu, which provides a quick way of restoring from one of your saved configurations, as well as providing a button to access to the Configuration Dialog and Options Dialog.

M - The Measurement Menu shows various optional commands, depending on the current mode and state, such as invoking instrument calibrations, measuring refresh rate, or clearing all the measurements.
