Gossen METRAHIT 2A

[kcs]

I miss Dave's DMM reviews, so I have decided to do my own review of Gossen METRAHIT 2A multimeter. Actually it is not a proper review, but...
I have bought it from eBay, it is used but looks like new. This multimeter isn't cheap. I am very happy with it, I like its built quality, the only thing that is not right is that when I adjust its ohm range for 10x, 100x or 1000x and then switch to 1x, I need to readjust it (look at the second set of photos). Comparision was made with Fluke 87 V. Everything seems all right except VAC.

I want to fix this issue with ohms range. I suspect that one or some resistors could be out of range and that they need to be replaced. Is it possible to get schematics for this meter anywhere? I was out of luck trying to find it on the internet.

Do you mean that you have to zero the meter each time you change ohms range?  If so, that is normal for an analog meter.

While I also think there is nothing to fix you could ask Gossen for a schematic. They do help people out, even with older models, if they have the information and if it isn't proprietary information.

Yes, exactly. It is strange that you say it is normal, as my old cheap Sanwa multimeters have not had that problem.

For Ohms measurement in the user manual Gossen says:
- choose your settings x1..x1000
- short the leads
- adjust the scale too fullscale
- measure your resistance

So with this meter you practically have to adjust your meter every time you change ranges.

About the AC Volts.
The Metrahit is a averaging Meter, the Fluke has True RMS capability, maybe that's the reason for the discrepancy.
But 28V difference seems a bit much, assuming you measureing mains.

Fox, I think you're reading off the wrong scale.

Indeed i did  , not used to read analog meters any more

Thank you all.
1. Ohms. If it supposed to work this way, let it be, but I would prefer to make no adjustments.
2. VAC. Yeah, I have made the same mistake reading the wrong scale.
