It can be selected whether the operator is reminded of the fact that a calibration may
has become necessary or not. The default value is off.
If the calibration request is switched on, a corresponding message will appear when
30 minutes have elapsed after power on or if the temperature of the UL1000 and
UL1000 Fab has changed by more than 5 °C (9 °F) since the last calibration.

This mode can be switched on and off.
If switched on the UL1000 and UL1000 Fab will not start pumping down before the
inlet ha
s not
dropped below

mbar. e.g. it is assumed that the part under test is
pumped by another pump in parallel.
Purpose: When the leak detector does not pump at high pressures no gas stream
,
possibly carrying particles gets into the leak detector.
