Field calculators and a troubleshooting library for low-voltage and ICT techs. The app runs both with no signal, and any result goes out as a Printout with your name on it.

Opens this in the VoltIQ app with your numbers. Add your name and the job, then save it or send it to the crew.
The Verdict
A green light can't tell a failed inspection from a callback next year. Every problem a VoltIQ calculator flags goes in one of three buckets, the way techs already sort it out loud.
Fails a code or standard limit. A tester or inspector will flag it.

TOO LONGLonger than the permanent link this channel allows once temperature and cords are taken off.
89.0 m installed / 84.6 m allowed at 35 °C
Shorten to 84.6 m, shorten the cords, or get the ambient down.
Passes today, fails later. It brings you back on a callback.

WITHIN SPECOver-cinched ties deform the jacket and crush pair geometry. This is the fault that tests fine on day one and drifts a year later.
hand-tight only: a tie should slide along the bundle
Passes and will last. A pro would still do it differently: no margin, no room to grow.

A passing stamp can still carry a WON'T LAST or a JUST UGLY. A WON'T PASS never sits under one.
Tools
Every result gives the reading, the limit it was measured against, a meter for how close you came, and every term behind the number. The calculators on this site run the app's own code.
54 symptoms across 8 systems, each with likely causes and steps. Read them here, or in the app with no signal. The app adds 3 checklists.
Type the question the way you'd say it on site. The answer runs under 60 words, action first, with the detail one tap away.
3 questions a day, free. Needs signal.
Inside the app
Big tap targets, the result pinned at the top while you change a number, and Roof mode for direct sun.
No signal needed
The calculators, the Verdict, the Printout and the library all run on the phone. ASK is the one part that needs bars.
What works
No signal. Everything but ASK still works.
Printout
Any result becomes a sheet for the crew thread: the job, the reading, the stamp, the fix, the math behind it, and your name across the bottom. Save it to the phone or send it from there.
