Chapter 4 – Functions of the instrument
UM-22100H-U User manual ATEQ D520 Page 98/122
Turn the key to the LOCKED
position.
Note: if the parameters have been modified and there is a difference between the
current and the saved parameters, when the instrument is switched on, or the key is
turned to the locked position, the following message appears on the screen:
SAVE PARAMETERS
This message does not block the instrument and disappears after a few seconds. It
informs that a save operation may be necessary. In this case, three solutions are
available:
1) Recover the saved parameters (the current parameters will be lost).
2) Save the current parameters in the memory (the parameters already saved will be
lost).
3) Do nothing and work with the current parameters.
4.2. SERVICING OF THE SENSORS
This menu allows the monitoring of the information that is communicated by the
pressure sensors, "PRESSURE" for the absolute pressure piezo sensor and "LEAK" for
the differential pressure sensor.
In the main menu, place the
cursor in front of the SERVICE
heading and confirm with the
ENTER key.
