Note: 1. The above values were obtained under test conditions with the standard mounting. The derating curve will vary with the mounting
conditions, so be sure to adjust accordingly.
2. Internal components may be deteriorated or damaged. Do not use the Digital Indicator outside of the derating range (i.e., do not use it in
the area labeled (1), above).
