NO: tare not executed; YES: automatic tare enabled.
QHD
For models T3LPFxxxP05 and T3LPFxxxP2 only, the pressure reading resolution is
pressures can be high or low resolution.
Changing the QHD parameter changes the format of the Q+ and Q- (leak limits) pa-
rameters, which must be reprogrammed, and the format of the pressure drop dis-
played in measurement phase T3.

Resolution 1 mbar +/- 60000 Pa (+/- 600.00 mbar).
An increase in pressure is an abnormal condition; a minimum pressure drop may be

with negative sign (leak with pressure drop).
The leak limit
, with negative sign, must always be lower than the pressure limit .
Examples:
= 50 Pa, = -10 Pa; = -5 Pa, = -10 Pa.
If the
limit is programmed below the limit, the limit value is automatically
corrected.
The test has
PASSED only if the pressure delta in time remains within the limits
