7.4.2. Transaction of the test with the measuring-equipment SHAFT
After conclusion of the data input, the actual test-screen is started. Doesn't yet start
the actual test but the screen-ad at first putting in of the beginning-water-stand as
well as the control of the attitudes allow.
This water-levels should be at beginning of the test between the two rings of the
level-sensor, what through variation of the water-stand or through beginning / sinking
of the level-probe can be reached.
RESPECT! Avoid out the sinking the sensor over the upper ring! A exposition of the
sensor-lensis can lead to measuring-mistakes at a subsequent test!
In the status-window of the test window, hints are given to the attitude of the test
level, in principle it should at beginning of the test of the upper third of the measuring-
area of 50 mm lies.
After conclusion of the water-level-attitude, the actual test is started by clicking the
start-button. Going out, the level-change becomes from the so-called zero-water-
stand captured to the post-time-point as well as. the water-loss over the test time
clung.
With application of the automatic water addition with the measuring-equipment
WATER, the behavior directs "automatic water-addition toward him/it at test-end" for
itself after the attitude of the counter in the section 7.4.1. represented parameter-
windows.
If this counter is active, so the water-addition takes place on the test-end (d.h). the
zero-water-stand is restored, he/it is inactive, so the level is held virtually steadily
through continuous water-additions. So, also tests with allowable level-loss can be
carried out over 50mm.
With application of the automatic water addition without the measuring-equipment
WATER, the test is not stopped after the actual test time. The record is continued
explicitly until the user on the button "STOP" presses. During this additional
measuring-phase, the water-addition can take place manually. After the pressing the
Stop-button over an input-window, the user must declare the manually added water-
quantity.
The value of the water-addition appears at activation in both cases in the test-
protocol.
