Revision 1
False Echo:
The "False Echo" shows the false signal strength in dB of the obstruction
reflections over the range specified by the user. The signal records an
envelope of the false signal of the measurement (for example, the
reflected signal from ladder of tank).
When the LCD displays menu number 3.1, press
key. The selected
curve is shown in LCD.
3.2 Start
Simulation
Simulation is a function only for simulation of the 4...20 mA current
output. It is used to check whether the current output function of the
instrument is normal or not. When the liquid crystal displays menu
number 3.2, press
to enter the simulation state. Display in LCD is
as follows.
Press
to confirm the simulation function. Display in LCD is as
follows.
Choose the current output mapping mode by pressing key, and press to
confirm. Enter the corresponding setting menu, and press to
confirm after completing the value setting. From them on, the
sensor current value is set to the corresponding value.
There are presently two options:
1.
Current: Output current at a set current
value.
For example, 16.6 mA corresponds to the
output of
16.6 mA.
2.
Distance: Output current at given Distance value.
The relationship between this value and current value is
determined by item 1.5, the minimum adjustment and item 1.6
the maximum adjustment.
