I've done a detailed review of the Bside ADM01 and ADM02 and RS-14. Why these? Because while waiting to for RS to get stocks of the RS-14, I spotted that the Bside meters are very similar, so picked them up - can never have too many multimeters, even disposable ones. All use the same IC, and all share problems as a result.
http://golbornevintageradio.co.uk/forum/showthread.php?tid=5501The reviews were done "chronologically", so start with the ADM01, then cover the differences in the ADM02 when it arrived, and the same for the RS-14 when it finally landed. For that reason, it might make most sense to read the entire thread if you can bear it. But skip to post #6 for the RS model. In the fullness of time, I'll re-write the content in a more logical form and place it on my website.
There are quite a few points raised that weren't mentioned in the video, such as the painfully slow response in ohms mode (the auto-ranging is fast, as shown in the video, but settling on a value within a range can take a few seconds), or the overshoot when reading volts. In many ways the RS-14 is better than those cheap Bside meters, but actually, it's not quite as clear-cut as that. For low voltage, low energy work, I'd take the Bside. The RS-14 is Cat III rated, but not independently verified as far as I've established so far, and although it's perhaps less likely to destroy
itself in a high-voltage transient event, I'm not sure if it offers better protection to the
user if it does blow up. The Bside is probably more robust because of the separate holster. The Bside might have a smaller display, but it has a *much* better viewing angle. The Bside doesn't slide around a hard worktop as you operate the range switch. But the Bside has horrid hard plastic buttons and "clicky" tact switches, and no manual ranging. But it's a lot cheaper.
If you're wondering about the forum I put that in, it's worth saying that a lot of folk in the UK vintage radio community see nothing wrong with those horrible sub-£5 meters, so I was hoping to demonstrate that moving up the food chain just a small amount gets you so much more in terms of accuracy, functionality and safety. Obviously all these meters are a way off Fluke's standards, but a step in the right direction, hopefully.
