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 On 10/1/19 5:07 AM, Martin Althoff wrote:
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}
