Fct. n° Text Description and settings
2.2.0. CURRENT OUT Sub menu 2.2.0. Current output
2.2.1. CURRENT? Not available
2.2.2. I 0% Calibration of the current output for i
0%
Measure the exact value on a milliammeter and press the “+” or
“-” key in order to obtain the wished value for i
0%
3 mA ≤ i
0%
≤ 12 mA
2.2.3. I 100% Calibration of the current output for i
100%
Measure the exact value on a milliammeter and press the “+” or
“-” key in order to obtain the wished value for i
100%
12 mA ≤ i
100%
≤ 21 mA
2.2.4. TIME CONST. Time constant for output of the measured values
Range: 5, 10, 15, 20, 25, 30, 50 m
2.4.0. SPECIAL Sub menu 2.4.0. Special functions
2.4.1. LANGUAGE Language for display text
“GB”: English
“F”: French
“D”: German
2.4.2. PASSWORD Not available
2.4.3. EEP PARAM. Display of the different parameters memorised in the
EEPROM: see section “2.4 Parameters Stored in the
EEPROM”. Read only.
2.4.4. FILTER Activation of an electronic filter for noisy applications
(foam, solid contents).
Select “YES” or “NO”, default setting “YES”.
2.4.5. DISPLAY Display of the actual velocity in m/s. The velocity is displayed
after quitting the programming menu.
Select “YES” or “NO”. Default setting “NO”.
It must be programmed to “NO” before you disconnect the
DWM 2000 D.
2.4.6. DIAMETER Diameter of the pipe into which the sensor is inserted. This
value is needed for calculating the flow rate. If you enter a
value of “0”, this switches off flow rate on the indicator display.
Refer also to the CAUTION that follows.
50 mm ≤ diameter ≤ XXXX mm
CAUTION
Do not use menu 2.4.6 to read the setting for the pipe diameter. This will reset
the value to default “0” and switch off the flow rate line on the indicator
display. Use menu 2.4.3 to read EEPROM settings (this includes DIAMETER).
If the value is reset to “0”, you must re-enter the pipe diameter in menu 2.4.6.
