1. The temperature probe looks like it is waterproof/sealed can I place it in a container of water or will it work better suspended inside the refridgerator?
2. I have set the unit to 5C with a .5c tolerance to switch back on but I note that when the unit hits 5C and turns off the temp continues to drop to about 4.3C is this normal?
3. There is a calibration setting at F4 do I need to set this and if so the instructions are a bit chinese/english and don't appear to indicate how to do this, can someone clarify how to calibrate the unit if needed?
