1. The device must be operative for at least 60 minutes before zero
point setting is started.
2. Connect pressure connections P (+) and P (–) with a hose
(differential pressure between the connections = 0 Pa).
3. Requirement: DIP-switch 6 is set to OFF.
4. To set the zero point, press pushbutton for 10 seconds without
interruption.
By pressing the button, a countdown of ca. 10 seconds is started.
The yellow LED is flashing and the countdown counter is shown on the
display (optional).
After the countdown period has elapsed, zero point calibration takes
place. This is indicated by continuous light of the LED, and on the
display (optional) by switching from "AUTO 0" to "PROG 0".
Note: When releasing the pushbutton during countdown (counter > 0),
zero point setting is immediately aborted !
Setup button assignment:
select
Pressing for more than 5 seconds =>
switches to setup mode
A short push following thereafter =>
switches to the next input value
respectively terminates setup mode
up ▲
(arrow pointing up) increases the input value. Keeping it
depressed increases the increment step by step by
which the parameter is increased.
down ▼
(arrow pointing down) decreases the input value.
Pressing for longer increases the increment step by
step by which the parameter is decreased.
Calculation formula – k-factor:
√
k = q ⁄ (Pi) q = volume flow rate in m
(Pi) = differential pressure in Pa
Adjustment range: 1...3000
