If you can't do upper and lower case - then just do all lower case it is much easier to read then UPPER CASE.

Not a problem if you are just using the analyser for your own info but if you have sites around the world providing data into one centre, it's a problem.
However, this aside, its a good device.

But, there are several problems. The non-existing sw compatibility backwards and forwards is one. The lack of anti-alias filters is another. I often get lots of even harmonics when looking at voltages where PWM inverters are connected. The reason is that high frequency components are folded down under the Nyquist frequency and are interpreted as odd AND EVEN harmonics. It does not only increase the apparent odd harmonics level, it also introduces even harmonics where there cannot (for physical resons) be any.
I also find the software updates pricey and I suspect that the lack of fw/bw compatibility is a policy used to force updates.
There are many other brands that not only behave better. They also cost less and the support is usually also better.

We have one of the earlier PM3000's and it is a good instrument, if a little dated by the latest designs with LCD touch screens and the like. Voltech usually have a loan instrument for potential clients to try out. I would be amazed if Yokogawa and Dranetz do not offer the same service.
