circuitikz meters

circuitikz meters

[Martin Althoff]

Hello ...

I am drawing some simple circuits for an electro-physics class I am teaching using
circuitikz. Using meters gives some effects I don't quite understand.

The MWE works as shown. The commented lines fail with "Undefined control sequence". If I
put the same 3 lines into Latex (via Texstudio on Linux), just the opposite happens. The
line with rmeter fails, the other two work. 

Why the difference? Some version issue? The "circuitikz manual version 0.9.4.pdf" shows
all 3 types of meters as choice. 

Actually I would prefer to use the "ammeter" and "voltmeter" within Context.

Thanks for any pointers.

Greetings, Martin

\usemodule[circuitikz]
\starttext
\starttikzpicture
%\draw (0,0)to[ammeter, t=A, i=$i$] ++(3,0);
\draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ;
%\draw (0,2) to[voltmeter, l=$U$] (++3,2);
\stoptikzpicture
\stoptext


Latex MWE, works as shown

\documentclass{article}
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}
	\draw (0,0) to[ammeter, t=A, i=$i$] ++(3,0);
	%\draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ;
	\draw (0,2) to[voltmeter, l=$U$] (++3,2);
\end{circuitikz}
\end{document}

Circuitikz uses \textbf inside, which is a LaTeX macro.  Unfortunately, this is
hardcoded within the ammeter and voltmeter nodes, so you can't easily change
it.  Instead you can simply provide a macro that does the correct thing.

\usemodule[circuitikz]
\let\textbf\bold % <---
\starttext
\starttikzpicture
\draw (0,0)to[ammeter, t=A, i=$i$] ++(3,0);
\draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ;
\draw (0,2) to[voltmeter, l=$U$] (++3,2);
\stoptikzpicture
\stoptext

Cheers, Henri

Thanks for that Henri. I didn't expect a simple thing like that. As I had some similar
"glitches" before, I'll have a look through the module.

All the best, Martin

If there are more such commands we can add them to the tikz module 
loader. Just collect them.
