Test Pressure 2
This parameter defines the test pressure for the Fill 2step. The Test
Pressure should be set to a value that complies with the test
specification of the test component. The programming limits and the
default value are dependent upon pressure units selected and the
pressure range of the unit.
To set the manual regulator output:
1. Turn the pressure regulator knob fully counter clockwise .
2. Use the left/right arrow keys to select regulator output.
3. Select On function key to display regulator output setting .
4. Turn the pressure regulator knob clockwise until the required test
pressure is achieved.
5. If required select, the
Update function key to set the Test
Pressure parameter to the displayed regulated pressure.
6. Select the Off function key to cancel regulator function.
Pressure Tolerance
This parameter defines the tolerance that the test pressure must be
within during the test cycle.
If the pressure at the test component exceeds the instrument upper
limit, i.e. " Test Pressure + Pressure Tolerance", an over pressure
error is detected and displayed.
If the pressure at the test component drops below the instrument
lower limit, i.e. " Test Pressure - Pressure Tolerance", a gross leak is
detected and the test cycle terminates.
The programming limits and the default value are dependent upon
the pressure units selected and the pressure range of the unit.
Auto Zero
This parameter sets the time period to allow sensors to be vented to
atmosphere and the final reading is then used as the new zero value
(reference point) for the current test.
The programming range is
0.0 to 5000.0 seconds and the default
value is 0 seconds.
Setting 0.0 time or disabling the individual sensor’s auto zero
parameter will disable the zero update.
Couple Time
This parameter sets the time period to allow for any output functions
controlled by the pneumatic couple output to operate before
pressurizing the component. The programming range is
0.0 to
5000.0 seconds
and the default value is 0.0.
If this parameter is set to 0.0 seconds, no valve or phase actions are
performed.
Fill Time
This parameter sets the time period to pressurize the test component
to the set test pressure. The programming
range is 0.0 to 5000.0
seconds and the default value is 0 seconds. If this parameter is set to
0 seconds, no valve or phase actions are performed.
