Changing the cross-sectional area:
If the key "Max" is pressed for a long time in the Flow mode with
the indication "m
calculating the rate of flow in m
In the Flow mode with the indication "l/min" the cross-sectional
area for calculating the rate of flow in cm
2.9) is displayed.
When the symbols "Max" and "Min" and the first digit of the area
indication flash, this cross-sectional area can be changed with the
keys "Max" and "Min". Changeover to the second digit takes place
with the key "Flow" and this too is changed with "Max" or "Min".
Now it is possible to continue as described above until all digits are
changed. A point (comma) is set with the key "Rep". This change is
terminated with the "Flow" key.
This cross-sectional area remains saved, also after the
instrument is switched off.
The minimum values of the parameters ∆ ∆ ∆ ∆ p, Flow, Temp. or
Baro are displayed with the key "Min".
If the key "Min" is pressed for a long time in the Flow mode with
a measured value indication with exponent (e.g. 3.6E3 m
sec.), then two additional decimal places are displayed instead of the
exponent. The unit symbol flashes to show that the unit of
measurement is incorrect. Return to the basic display takes place
with the key "Flow".
Extension of the resolution:
When the measuring instrument is switched on via the "On / Off"
key, the display has a resolution of 0.05% of the upper limit for
pressure within +/- 10% of the upper limit (20 - sec. – mean value).
A pressure greater than +/- 10% of the upper limit is still displayed
at 0.5% of the upper limit (2 - sec. – mean value).
In individual cases it can however be useful in the range +/- 10% of
the upper limit, to reduce the measuring accuracy in order to obtain
a shorter quasi instantaneous value (2 - sec. – mean value) on the
display. This changeover takes place as follows:
If the key "Min" is pressed for a long time in the ∆ ∆ ∆ ∆ p mode (ca. 2
sec.), the measuring accuracy is reduced to 0.5% of the upper limit
over the full range of measurement.
