Overview
Helps reduce measurement errors and false rejects due to part temperature effects.
Compensation graphs viewed on large LCD screen.
Easy setting for mapping of the graphs.
Temperature compensation mapping should be adjusted on the actual production line.
The temperature difference between the part and the environment is measured to carry out the Temperature Compensation according to the correlation between the temperature difference and measurement errors.
Major applications
Post-cleaning leak tests, engine parts (cylinder head, cylinder block)
(a correlation should exist in the differential pressure between the temperature of Work and the applied air)
