NOTE!
Change the default values for underfill time, pause time and tare time
only after consulting the manufacturer.
Underfill time: 0.3 s, Pause time: 1.0 s and Tare time: 0.5 s.
Set the times so, that an open specimen connection will cause a rap-
id shut-down.
The underfill time must be in the range from 0.00 10.0 seconds.
It is within the stabilizing time and has no influence on the duration of the test cycle.
Default value is 0.30 sec.
Test pressure:
ATTENTION!
With a pressure/vacuum unit do not enter a fill/test pressure of
0.09 0.19 bar/ü.
The value should be 0.2 6.00 bar.
Default value is 0.90 bar.
Pressure tolerance:
The value should be 0.5 10.0 % and it is the tolerance of the pressure regulation in
% of the end value.
Filling:
Enter the fill time in seconds from 0.10 999.99 seconds.
Default value is 3.00 sec.
Stabilize:
Enter the stabilize time in seconds from 0.10 999.99.
Default value is 3.00 sec.
NOTE!
Change the values for underfill time, pause time and tare time only
after consulting the manufacturer. Accept the default values for the
underfill time: 0.3 s, Pause time: 1.0 s and Tare time: 0.5 s.
In case of low test pressures (approx. <0.5 bar) or low volume spec-
imen (approx. <100 ml) the pause and tare times may need to be
shortened (possibly no test pressure in specimen).
The times must be set in such a way, that an open specimen will trig-
ger a rapid shut-down.
Pause:
Enter the pause time in seconds from 0.10 999.99.
Default value is 1.00 sec.
Auto Zero:
Enter the auto zero time in seconds from 0.10 999.99.
Default value is 0.50 sec.
Measuring:
Enter the measure time in seconds from 0.10 999.99.
Default value is 3.00 sec.
