Really useful and very powerful and versatile .
Initially was quite daunting to learn, but the actual process is straight forward once you start.

junwei is in Kuching. You need to provide him accommodation too ;D
Eh, I thought you have someone to do for you on REW? No?

no problem, I can fly in once every few months and do it for West Malaysian Brothers And probably stayed at Maxx Shop ...part-time security Guard hahahaha... Get a few customers and I will fly in for 2 days and do the calibration for you guys ..just enough to cover the cost and get some back for my gears |

I have both the RS meter and the calibrated Galaxy CM140+.
For general level matching, the analog RS is easier to use especially for the subwoofer calibration level.
With the CM140, the digital reading really go up and down rapidly over at least 2-3dB and is quite difficult to determine which is the right reading.
Sometimes it will display and hold one reading a little bit longer and I will use that as the right level..
If you intend to do REW, then do get the calibrated one as it is more accurate.
I find my RS under measure by -2dB relative to the Galaxy.

After comparing a single mic and multiple mics calibration, the readout on a single is way different from multiple mics .. taking height of the mic and position of internal furnishing will greatly affect the result of a single mic.
using spatial average , probably try use REW and get few readings and have REW sum them up ..then maybe the result is more accurate ...
AS for the CM140, I totally agreed with klimal ...the readout fluctuates fast ...it's hard to read ...getting a calibrated mic will do the trick but some calibrated mic are expensive....

I have very brief experience with CM140. It is quite a challenge for me to get the reading too as I am too used with RS

In fact , if calibrated with an inaccurate mic or even not setup correctly (wrong mic direction or blocked by something), you probably will get the wrong reference number. Then you set the AVR to 0dB thinking it's reference, but in fact, it could be louder ...then you stands a higher chance to damaging your equipment.... Gotto be very careful with that.
