Before any handlings „Safety Instructions" must be fully read!
3.0 Adjustment Procedure
3.1 Zero point adjustment in stationary medium (roughly):
Adjust zero point potentiometer after 2 min. so,
that Ia » 4 mA, i.e. at Ia > 4 mA turn pot. to the left,
3.2 Measuring range adjustment at max. flow: Measuring range:
adjustable from 0-20 cm/s to 0-200 cm/s (medium water).
Accelerate flow of the medium to a point, where the flow-captor
should give an output signal of 20 mA and wait min. 2 minutes.
Turn range pot. until Ia = 20 mA (to the left Ia will be bigger, to
the right Ia will be smaller).The color of the LED will change from
green ( Ia £ 20 mA) to red (exceeding measuring range).
3.3 Fine adjustment of zero point: After at least 3 minutes standstill
of flow turn zero point slightly so, that Ia is just 4 mA ( turning
direction as in 3.1) .
3.4 Repeat adjustment according to 3.2 and 3.3 until the zero point
( 4 mA ) and max. range setting ( 20 mA) remain constant.

Calculation of the standard height for
1/7 ID (insertion depth)
Hs = L
- W - (1/7 x ID)
1
Hs: standard height
L
: unit length (see drawing)
1
W: wall thickness of pipe
ID: inner pipe diameter
For example:
L
= 143 mm
1
W = 5 mm
ID = 50.4 (2")
Hs = 143 - 5 -(1/7 x 50.4)
= 143 - 5 - 7.0
» 131 mm
