I use a digital "roast" thermometer.

It's a probe, a cable, and a digital readout that sits on the countertop.
They sell for about $5 now. ( thank you China )

You "adjust" oven temp by moving the OVEN dial to match the actual temperature.
1 Pick an arbitrary temp.... 350 degrees
2 Set the oven dial to 350
3. Wait 15 mins for the oven temp to stabilize.
4. If your oven thermometer reads 350... you're done.
ELSE
5 Pry off the oven dial. there's usually a setscrew underneath.
6. Loosen the setscrew, rotate dial until it matches the thermometer reading.
7. tighten the setscrew.
8..replace oven dial.
DONE
