Zero offset compensation
Zero offset compensation
When putting the device into operation, check the zero point indicated in the display.
If, due to the mounting, an offset is displayed, a reset can be made in the programming mode
using the parameter 0SET.
„„ For relative or vacuum measuring ranges, make sure that the device is depressurized
before carrying out a zero offset compensation.
„„ For absolute pressure measuring ranges, the zero offset compensation must be
carried out in a vacuum, that means at 0 bar absolute. Due to the fact that special
references are required for this, we recommend to have this work carried out by the
manufacturer.
