Temperature Calibrating the IBBQ-4T on the inkbird app

How can I calibrate the inkbird IBBQ-4T probes on the inkbird app. The temperature on the probe I’ve used is out by at least 10 degrees Celsius

The IBBQ-4T can be calibrated to a range of ±12°F/ ±7°C. The 10C deviation exceeds the calibration range setting.
Please put the probe and the probe’s cable (excluding the probe’s plug) in an oven at 150C (302 F) for 30 minutes and then test with boiling water (please hang the probe so that it does not touch the container). Does it work?

Please note that the cable of the probe (silver wire) is not waterproof. Please do not immerse the cable in the water when washing the temperature probe.
Otherwise, it will show an incorrect temperature if there is water in the cable.
Please do not put the probe/the probe’s cable in the fire or in a place where the temperature is higher than 250C/482F. Otherwise, the probe and cable will be damaged.
