How about a circuit symbol?

Since an ohmmeter is a standalone test instrument and is not used as part of a larger circuit, it does not (as far as I know) have one. 86.159.159.194 (talk) 12:42, 12 October 2012 (UTC)[reply]

Sorry, I reverted the page while another user did the same. It's ok now.

I've added an image of an ohmmeter, although it's not that clear. I'm sorry for that, but it's the best I can do.

Multimeter image

[edit]

The multimeter in the second image is not even set to measure resistance, and is thus not currently an ohmmeter. — Preceding unsigned comment added by 190.166.230.210 (talk) 21:29, 11 February 2016 (UTC)[reply]

I think that's because it's turned off, which is why the pointer is in idle, but you get the point.2A02:587:4511:2200:CDEA:2643:DBE7:52CD (talk) 01:41, 1 July 2017 (UTC)[reply]

Specifications needed

[edit]

Halo, I am an unregistered user as of now (until I find time to register), but I made some modifications to the article (basically at 3rd and last paragraph) to make it more easily understandable to lay persons (like me). I am no expert and can't add any real new information, I just tried to clarify some points without changing the essence at all. If anyone thinks they should correct anything, please do.

As for the 4th paragraph, quote "A more accurate type of ohmmeter has an electronic circuit that passes a constant current (I) through the resistance, and another circuit that measures the voltage (V) across the resistance. According to the following equation, derived from Ohm's Law, the value of the resistance (R) is given by: R =V/I), it contains some points that need clarification for the non- expert: What's the difference between the ohmmeter described herein and the next paragraph's "precision" ohmmeter? Are they the same or different? At any rate, in both cases the instrument is described to measure voltage, not resistance. How does the current gets measured? Does the instruments involved contain two galvanometers, one to measure current and the other to measure voltage simultaneously, or you measure current first, voltage afterwards and extrapolate resistance? Clarifying these points, though they may be self evident to some, would make this article more easily accessible to people without prior knowledge (like me!) 2A02:587:4511:2200:CDEA:2643:DBE7:52CD (talk) 02:06, 1 July 2017 (UTC)[reply]
