24 Function
6.3 Managing the Test Results Sartocheck
®
4 plus Filter tester processes the measured raw data (the test results),
which means that the unit values are converted and numbers transformed into text.
6.4 Function Test With the function test, the user is able to interactively test the functionality
of pneumatic components. The proportional valves are not explicitly, but rather
implicitly tested in this context.
6.5 Cleaning Sartocheck
®
4 plus Filter tester starts the procedure for cleaning and flushing the
internal lines and the volume reference tank.
6.6 User Interrupt The user can interrupt any test on Sartocheck
®
4 plus Filter tester by pressing the
[STOP] button. Pressing the [arrow upwards] and [STOP] buttons simultaneously
will interrupt tests on all Sartocheck
®
4 plus Filter tester MultiUnits or
Sartocheck
®
4 Bag tester MultiUnits connected to the Sartocheck
®
4 plus Filter tester,
as well as any test running on the Sartocheck
®
4 plus Filter tester unit.
6.7 Self-Test for Broken While controlling the valves and sensors, the Sartocheck
®
4 plus Filter tester
Conductors and Short-Circuiting hardware can check whether there are any broken conductors or short-circuits.
6.8 Calibration The calibration function is designed to calibrate the internal pressure sensor with
the help of more accurate reference measuring equipment, and if necessary, adjust it.
The sensor has a monitored calibration date.
An adjustment routine automatically follows the test. The test can also be activated
separately. Sartocheck
®
4 plus Filter tester saves the raw data for the calibration
record in permanent memory.
The operator can use the following sensor type for determining the reference
pressure:
t Relative pressure sensor:
The measured reference pressures relate to the ambient pressure. The ambient
pressure must be known or measured with additional reference measuring
equipment.
6.9 Internal Pressure Sensor Sartocheck
®
4 plus Filter tester sets 8 pressure values and compares them with
the internal pressure sensor and the pressure values measured on the reference
measuring instrument (connected to the “OUT” connector) to calculate scale
and linearization.
6.10 Pressure Gauge Function When in the pressure gauge function, Sartocheck
®
4 plus Filter tester acts like
a digital pressure measuring device.
6.11 Cleaning | Drying Through the pneumatic connectors, Sartocheck
®
4 plus Filter tester is able to
flush almost all internal volumes. It is the responsibility of the user to use original
Sartocheck
®
equipment only (Cleaning Kit type 26288---CK”).
6.12 Safety Functions t As one of its technical options, Sartocheck
®
4 plus Filter tester runs the test step
Initialization | Security Status in the event of a power failure. Basically, what this
step does is close the compressed air supply and the block valve to the test set-up.
t Sartocheck
®
4 plus Filter tester is not responsible for ensuring whether the
pressure supplied to the system being tested is too high. This means that the
user must make sure that the programmed pressure cannot damage the system
being tested.
