Oven thermometers are designed to remain in
the oven to verify that the oven is actually heating to the desired
temperatures. It is important that the temperature is set at 325 degrees
F or higher when cooking meat and poultry. These oven thermometers can
measure temperatures from 100 to 600 degrees F.
When checking the accuracy of an oven, just
hang the oven thermometer from a rack in the center of the oven. Then
set the oven for 325 to 350 degrees F and allow it to preheat. Open the
oven door and read the thermometer once the oven has reached the set
temperature. Most ovens maintain their temperature by cycling on and
off, especially when the door has been opened. After 5 minutes, check
the temperature again.
If you find that the oven is not maintaining
the set temperature, the oven thermostat will need to be calibrated. Do
not calibrate it yourself, get it done by an authorized service center
representative. However, if after testing the oven temperature with
different settings and it is consistently higher or lower by a certain
degrees, it could be factored into the temperature setting. For example,
if you discovered that your oven is always hotter by 25 degrees F and you
need to cook at 350 degrees F, just set the oven for 325 degrees F.
Always check the oven thermometer to verify the correct temperature.
