Using this pocket - probe pyrometer is easy. First, make sure you're within the 50 to 400 degrees Fahrenheit temperature range. Since it's a plug - in type, find a suitable power source (you'll need to provide your own cords). Just insert the probe into the area where you want to measure the temperature. For best results, keep the probe clean and dry. Don't expose it to extreme humidity or rough handling. After each use, put the pocket - probe back into its metal case and store it in the original cardboard box. This will help keep it in good condition. And remember, even though it seems new, it's untested, so use it with a bit of caution.
