The Display

Nope.

Connections

Nope, no connections either.

The Reset Button

Nope again.

Power

Still nope.

Temperature Probes

Well, maybe you can call this a temperature probe:

Temperature Probe Accuracy

Again, nope. There is no accuracy to measure since the bi-metal coil shaft doesn't have temperature markings.

Calibration

And likewise, nope. Since the bi-metal coil has no temperature markings and therefore there is no accuracy involved, there is no calibration to be done.
