Do not alter the casing by forcibly reaming the holes for bigger screws or even opening new
holes.

For the all-time use, it is recommended to use the thermometer in an environment less than
70 to 80 % of the maximum measuring range. Otherwise, it will be the cause of malfunction.

Immovability of the pointer

leakage from the bourdon tube or the welded area.
