Only carry out zero point setting for gauge and vacuum pressure measuring ranges at the start of the measuring range.
Carry out zero point setting of absolute pressure measuring ranges at 0 bar absolute (vacuum). Since
appropriate references are required for this, we recommend that this is only carried out by the manufac-
turer.
