about 12” (max. 18”).
2. Cleaning probe tubes
DO NOT REUSE probe tubes. There is NO recommended cleaning proce-

cause test result errors. DO NOT cut off any portion of the tube.

a car key, and scratch the surface of the paper on both sides. If a black mark
appears it is thermal paper. If not, it is plain paper and will not work.
