Are the rpm and temp gauge accurate ib te MT-4. I just ordered one

i didnt put the RPM sensor, but the temp i pretty accurate.

Recently I found my AT temp sensor read ~10F lower than my ChinaFreight temp gun. "The hell..." I thought. "I'z a engineer... need data."

So I got out my new(to me) Fluke 87 Digital Volt Meter with Included Thermocouple Sensor. Those cost ~$400 new (got mine used!) and are reputed to be very accurate.

The Fluke reading was within 1F of the AT sensor.
