   Test results

 

 

The test is ended with a 

failed

 result if, at the end of the "Dp

measure" time, the measured  pressure  decay - as  absolute
value   without   sign   -   is   equal   or   higher   than   the   set   Dp
maximum limit.
The red led blinks up to the beginning of a new test.

The test is ended with a  

good

 result if, at the end of the "Dp

measure" time, the measured  pressure  decay - as  absolute
value without sign - is lower than the set Dp maximum limit.
The green led blinks up to the beginning of a new test.
If   the   manual   pressure   discharge   option   was   selected,   the
pressure   drops   down   when   the   operator   disconnects   the
tested part, and then the green light turns off and the display
changes to the message indicating ready for a new test with
the selected table.

   Alarm indications:

 

    Causes and solutions

 

 

Under alarm conditions, the test in progress is cancelled.

- TABLE No.  XX  

Error in the parameters stored in the eeprom.
Reprogram the test table.

- CONFIGURATION

Error in the parameters stored in the eeprom.
Reprogram 

all

 the parameters of the "CONFIGURATION AND OPTIONS" menu.

- CALIBRATION

Error in the calibration constants of the pressure transducer.
Carry out the calibration procedure.

- PRESSURE

Error in the reading of the pressure transducer.
It is necessary to repair the device.

NOTE

: 

Until these operations are not carried out in the correct way, the device won’t
be ready to start the test.
