I have just bought an RT301WA and reading the instructions here.
The calibration makes no sense at all. it says place the thermometer in a temperature calibrator...which is what? I have no clue what a temperature calibrator is.
There is another piece of info I found on the website: "Adjustable Calibration

Under the sealed SS screw in the front panel is an adjustment screw that allows you to re-zero the thermometer in an ice bath, and remove minor errors if ever needed. However, thermometer readings should remain within the ±0.9°F spec without adjustment."
This makes more sense....but I dont know how to prepare that ice bath. Isnt it a bunch of ice cubes left in a glass in the fridge till they melt and produce enough liquid for the probe? I think that's what I read somewhere before.
