FEATURE DESCRIPTION
Wait for
<Enter> to tare
(check box)
If checked, COMPASS waits for a user response before proceeding with the tare
procedure. If not checked, COMPASS automatically executes the tare
sequence and activates the new tare value without operator intervention. In both
cases the
<Tare> panel is displayed with a real time update of molbox tare
information (see Section 6.6.2).
Do not check this option if you wish to run a completely automated test
without operator intervention.
Tare Pressure
(drop down list
selection)
Select whether the <Upstream> or <Downstream> molbloc pressure should be
used for taring. COMPASS automatically adjusts the molbox valves to connect
to the selected tare pressure. The tare pressure should be the pressure that
remains the most stable during the test. Generally, this is the upstream pressure
if the molbloc is upstream of the DUT and the downstream pressure if the
molbloc is downstream of the DUT.
