I have a similar model and it is very useful if used properly. An analog meter can actually be a better tool than a digital as it gives you a visual relationship of two or more readings rather than just numbers. If that meter is the same as mine you can do alternator amperage output diagnostics up to 100 amps, you will not be doing that with your hand held meter anytime soon.
My model number is slightly different. If you want I will try to get the manual copied and sent to you
