Here's step by step guide to calibration (of really any projector) but with a JVC RS40/45/X3/X30 bias.
Attached is the word doc of the same that contains some screen shots of HCFR as well. I will updating the document to its RS45/X30 equivalent on the next and (hopefully) final calibration.
AVS-709 Disc 2
•\tColor HCFR 10% IRE step fields: Title 104
•\tColor HCFR 10% IRE step windows: Title 91
•\tColor HCFR 100% IRE Color fields: Title 9
•\tBasic Settings (black level/contrast): Title 39

2.\tSet Iris – use basic plunge : set to -10 currently
3.\tPlace sensor and calibrate
3.1.\tMaximize Y reading in placements
4.\tStart with Cinema, Standard Space, 65K temp, Gamma Normal – measure grey & color
4.1.\tGamma on Normal? - measure grey (closer to 2.1 for me)
4.2.\tColor space to Normal? - measure grey (closest to 2.2 for me)
5.\tAdjust black level & contrast - measure grey & color
6.1.\tUse 80/30% or 90/30% IRE fields
6.2.\t If 100% or other IRE needs minor work, use gamma RGB controls to tweak
•\t Never use all three gain controls (will squash contrast)
•\t Don't increase offsets (will raise black level)\t
•\t Don't mess with green, use blue/red to get match green
6.3.\tUse gains first, with 90/80% IRE ("Complete Program Menu" -> "Advanced Video Test Patterns" -> 1080p or 720p -> "Window 80% w/ PLUGE")
6.4.\tenable the "cont readings" option and adjust the gains until the RGB levels are @ 100% or very close
6.5.\tThe sensor will now start taking x, y, and Y readings and report them back every few seconds. You should see the data in the "Selected Color" window in the lower left.
6.6.\tBefore getting all the way to 100%, go down and pull down RB offsets. Not as much gain will be needed if some offset is used as well and vice-versa. Go back and forth between gain and offset adjustment to try to use minimal changes to get 100% @ 30/40 and 80/90 IRE.
6.7.\tOnce all three are close to 100% you should be close to the D65 point (x=0.313 and y=0.329).
6.8.\t Use offsets to adjust the 30/40% IRE
188.8.131.52.\t until all three RGB Level bars are at 100% or very close.
6.9.\tGo back and check 80% IRE and then 30%, rinse, repeat.
6.10.\tRe-measure our entire greyscale from 0 to 100 IRE - measure grey
•\tAdjusting RGB Offsets does not have much of an effect on readings above 50 IRE so it will not affect 80 IRE much. Therefore adjusting RGB Offsets usually does not require an adjustment of RGB Gains to compensate.
•\tAdjusting RGB Gain has a *large* affect across the entire greyscale. Adjusting RGB Gain will require an adjustment to RGB Offset to compensate. This is why we adjust the RGB Gain first.
•\tThe red and blue levels interact: Lowering one raises the other and vice versa. In fact, as you've probably noticed, everything affects everything!
•\tIf you're keeping your eye on the x/y readings, you'll note that the red controls affect x while the blue controls affect y.
•\tMake adjustments slowly to allow sensor to adjust
•\tIf you have to sacrifice somewhere, sacrifice the 70-100 IRE range as most of the content is under that range.
•\tIf your greys at 10 and 20 IRE look reasonably grey and 30 IRE measures close to D65 then good enough!
•\tif you find one of the colours dropping off significantly above 80 IRE, try reducing your contrast to see if the problem resolves itself.
•\tDelta E <=3 Great; <=10 very good;
7.\tRedo brightness & contrast
7.1.\tFor contrast we want to ensure that we're still within the expected ftL range (12-16 ftL)
7.2.\tFor brightness you want to make sure that you're not losing details into black (black crush due to brightness set too low), or that the colour black now appears grey (brightness set too high). You may have to change brightness by a notch or two at most.
7.3.\tRepeat Step 5.
8.\tColorHCFR has a great feature to allow you to compare data from two files. By marking one set of data as the "reference measure", all other sets will be compared against that reference. To do this simply load your before and after data files, select the before file in the "Window" menu, and click on the "Reference Measure".
9.1.\tAdjust gamma RGB controls to get a flat color response for lumenince
9.2.\tRe-check black level/constrast
9.3.\tRe-check grey scale
10.\tAdjusting the colour control
10.1.\tstart taking continuous xyY readings by clicking on the green arrow icon. Target red and hope that other colors follow along…
10.2.\tCue up your AVS HD 709 test disc and skip to the 100% white window pattern by selecting "10% Grayscale" -> "100% Gray window". 100% means that the window is at 100 IRE. Write down the Y (Luminance or brightness) .
10.3.\t Skip to the 100% Red window pattern by selecting "100% Saturated Colors" -> "100% Red window".
10.4.\t Adjust the colour control on your display until the Y reading is 21% of the 100% white window reading measured earlier. For example, if the Y value earlier was 39.012 as seen above, then 21% would be 39.012 x 0.21 = 8.193.
11.\tAdjusting the tint control
11.1.\tSince the tint control affects all three secondary colours we pick one (cyan in our case) and adjust to that and hope that the others follow along. A comprehensive colour management system (CMS) is required to set all three secondaries correctly.
11.2.\tSet your display's tint setting to the midpoint (default) setting.
11.3.\tEnsure that ColorHCFR is still in continuous read mode. If not, click on the green arrow icon again.
11.4.\tCue up your AVS HD 709 test disc and skip to the 100% Cyan window pattern by selecting "100% Saturated Colors" -> "100% Cyan window".
11.5.\tWe want to try and achieve an x/y reading as close to perfect as possible for the colour Cyan based on what colour space you chose earlier in this guide. If you can't remember, check the "Advanced -> Preferences" menu option and click on the "References" tab.
The SDTV - REC 601 (NTSC) cyan target is x=0.231 / y=0.326
The HDTV - REC 709 cyan target is x=0.225 / y=0.329
Note that the Cyan points for the three different colour spaces are very close to one another. The DeltaE is less than 5 between any two of these points. Getting close to any of these will result is what we can consider a pretty accurate cyan secondary. If you had to adjust the tint considerably away from the midpoint to have it read close to accurate however, there's a good chance that the other two secondaries (magenta and yellow) will be off. The targets for magenta and yellow are:
For PAL/SECAM the magenta target is x=0.327 / y=0.157 and the yellow target is x=0.417 / y=0.502
For SDTV - REC 601 (NTSC) the magenta target is x=0.314 / y=0.161 and the yellow target is x=0.421 / y=0.507
For HDTV - REC 709 the magenta target is x=0.321 / y=0.154 and the yellow target is x=0.419 / y=0.504
Measuring primaries and secondaries:
1.\tThe ColorHCFR software will now ask you to display primary and secondary (100% saturated) colours, one at a time, pausing at each one so that the sensor can take a reading. 100% saturated means that the brightness of the colour must be 100IRE or completely 'on'.
2.\tSimilar to measuring greyscale, we hope to achieve a DeltaE for all six primary and secondary measurements of 10 or less with 3 being even better. In our Barco Cine 8 Onyx projector example you can see from our results above that all values are under 10 so we're happy!
3.\tPay more attention to the DeltaE numbers than what you see on the CIE diagram until you become accustomed to reading a CIE diagram.
4.\tHow are your secondary values? Is the cyan DeltaE much lower than the magenta and yellow DeltaE? If yes, we suggest jumping back to STEP 8.3 and re-adjusting your tint control to try and even out the error between the three secondaries.
