The pressure required on measuring head to obtain zero reading must remain constant over the whole range. Upper limit of forming temperature is based on measurement signal. In addition to that, we will have an overview of angle comparators (autocollimators). 4. So if there is a close by object, the air can not so readily escape and the result is that, the pressure increases in the sensor output port. The accuracy of the readings should be within close limits of the various sizes and ranges 5.
