Operating mode AUTO – calibration (programmed steps)
Purpose:
The operation mode AUTO (automatic regulation) is chosen for the calibration of test
devices in preprogrammed steps. This makes sense and is timesaving if several test
devices have to be calibrated with the same pressure sequences.
Device function and schematic diagram:
The operation mode AUTO has the same device functions as the
calibration mode CTRL. Additionally a pressure sequence can be
started once or several times by a simple program.
The pump is on and regulates the respective pre-programmed set
pressure value. The internal reference pressure sensor, whose
measured value is shown in the middle of the display in each case,
supplies the actual pressure value.
Connection of the test device:
Differential pressure test device: Connection to „Plus“ and „Minus“.
Relative pressure test device: Connection to „Plus“.
Programming:
o
Press MENU
o
Submenu „Mode“:
press UP or DOWN until AUTO is indicated. Selecting
with OK .
o
Note: The sub menus „range“, „unit“, „steps“ in the main menu is of no
importance in AUTO, therefore it can remain unchanged.
o
Submenu „Settings“:
By pressing OK, a further menu overview is opened, in
which at this stage only the submenu „Auto-Modus“ is relevant.
o
Submenu „Auto-Mode“
selecting with OK
Submenu „range“:
Define maximum calibration pressure
(buttons UP, DOWN, 0%, 100%, confirm with by OK). Possible
value ranges see chart.

0519.0818

1100 hPa
Submenu „Unit“:
Define requested pressure unit (buttons UP
and DOWN, confirming with OK). The maximal calibration
pressure (Submenu „range“) is being converted automatically
Submenu „Steps up
“: Define requested number of rising
pressure steps (buttons UP, DOWN, 0%, 100%, confirm with
OK).
Example:
at range/unit = +1.000 hPa and „Steps up“ = 4 the
sequence is: 0 hPa, then 250 hPa, then 500 hPa, then 750 hPa,
and finally 1.000 hPa.
