place on forehead for 4 minuites and you should get a accurate reading.
It stays at the maximum point so you get an accurate reading
The temperature of your hand affects the reading of the thermometer.
The reading is not accurate if it is not in the liquid that you are measuring. Once you take it out, the temperature will be measuring the air.
In the center of the the refrigerator
You should place is along the wall.

Generally thermometers are calibrated two ways . primary calibration or Secondary calibration. In secondary calibration , two thermometers are kept side by side under same conditions and identify the difference with respect to one thermometer. In primary calibration , thermometer that to be calibrated is placed in a ice cubes made of pure distilled water . Now pour some distilled water and stirr well . Now place thermometer inside that mixture This will give the Melting point temperature of pure water 0 degree centigrade. Now see the reading on thermometer and adjust reading. This way of calibrating a thermometer is accurate enough form most applications.
If you are referring to using a surface thermometer, no.

A thermometer which utilizes a gas(vapor) to react to temperature changes for an accurate reading. (Instead of a hazardous material such as a mercury filled thermometer.)
