4.2
The "Analog" tab allows free configuration and
scaling of the twoanalogue outputs
Range:
The drop-down input field is used either to select a
standardised output signal (0-5 V, 0-10 V, 0-20 mA,
4-20 mA) or to specify a user-defined current/
voltage output range (e.g. 1-9 V).
Measurement
Specifies the physical quantities the outputs will
value:
represent.
If the measurement value "volumetric flow rate" is
selected, the cross section has to be defined (see
chapter 4.5 Cross section).
Upper / Lower
Specifies the required display range. The limits must
Limit:
lie within the maximum span as indicated.
Physical quantity:
Allows a user to choose whether measuring results are displayed and output in
SI units (m/s; °C; m³/min) or US units (ft/min.; °F; ft³/min.).
4.3
With an optional display, the following can be set on the Display tab:
"Display Mode" drop-down input field:
- Single-line display
- Two-line display (factory setting)
"Backlight on" check box
- Activated = ON
- Not activated = OFF
4.4
As described under Hardware, chapter 5.2 - Jumpers for Setting the Velocity Response Time, three
different response times can be set.
In the factory settings, the following response times are assigned to the 3 jumper positions:
Jumper at position 1: τ
Jumper at position 2: τ
Jumper at position 3: τ
Users can also assign a response time of between 1.5 and 40 s to each jumper position using the
configuration software.
Example:
Jumper at position 1: changes from 2 s (factory setting) to 35 s.
The green pilot lamp next to the jumper position indicates which jumper position is
currently set and consequently active.
Note: If the response time of the jumper currently active is changed anduploaded using the
"Write" function, the sensor's velocity response is switched without changing the hardware
(jumper position).
