If this so manually established „Zero-Offset“ must now be saved the key
ENTER must be pressed. The new „Zero-Offset“ is now saved in the
sensor head. Immediately after this, the selection pointer jumps to the
measuring mode absolute and the measuring result under consideration
of the new „Zero-Offset“ will be displayed. The following new value will
now be displayed in the absolute mode:
„ZERO-OFFSET“ is stored in the sensor head
Displayed value =
Value of the sensor minus „Zero-Offset“.
Remarks: Until the input is confirmed by using the ENTER key, every manipulation can be
stopped any time by pressing
SEND/ESC
Result:
Despite the fact that the sensor is still mounted
at the same angle the display of the
Levelmeter 2000 now shows the value
0°00‘00‘‘ This is the so called virtual ZERO
This new virtual ZERO is the reference for all
the future measurements based on this angle
(originally 0°07‘20‘‘)
II) Automatic set-up of the virtual ZERO
Practically quite often a measuring surface is not absolutely horizontal but should be the reference plane for other
measurements. In these cases it is useful to set the basic value for this surface to: 0°00’00‘‘
This can be done by manually setting the virtual zero as described before or by automatically define the value
with the Levelmeter 2000 set-up. (It is done by using a reversal measurement mode without turning the sensor
180 deg.)
Procedure
Initial position:
The display shows the measured value on the
Levelmeter 2000 : +0°09‘16‘‘. This value is the
true inclination of the sensor.
The selection pointer must be moved below the marking ZERO in the
display of the LEVELMETER 2000 by pressing the key
ON/MODE
several times. If reached the selection must be confirmed by pressing
ENTER.
The last computed or manually entered value „Zero-Offset“
The direction indicator is flashing
The sensor must now sit at position one and after a few seconds settling
time allowed, by pressing the key
HOLD, the first reading is collected.
This first value is displayed and the selection pointer below ZERO is
flashing which means the second reading is expected.
