4.0 Adjustment Procedure
4.1 Zero point adjustment in stationary
medium: Adjust potentiometer P2 after
5 minutes so that Ia = 4 mA.
i.e. if Ia > 4 mA turn pot. P2 slowly to the left
if Ia < 4 mA turn pot. P2 sowIy to the right.
4.2 Adjustment of measurement range at the max. flow rate
which is to correspond to 20 mA output: After 3 minutes at max. flow-rate turn
pot. P1 until Ia = 20 mA.
i.e. if Ia > 20 mA turn pot. Pl slowly to the right
if: Ia < 20 mA turn pot. P1 slowly to the left.
4.3 Check Zero Point and Range
Check zero and range adjustments as in points 4.1 and 4.2 and correct any
discrepancies as necessary.
4.4 LED indicates operation within measurement range, and switches oft when
flow speed is out ot the adjusted range (Ia>2OmA).

2.0 Installation Instructions
2.1 Installation Depth
Dependent upon duct diameter, min15 mm,
2.2 Orientation
Position the ceramic sensor elements so that they are parallel
to the direction of flow, as illustrated below.
2.3 Installation Site
Optimal installation is with a straight free run of 5-7 x ID diameter upstream
and 3-5 x ID diameter downstream ot the vent-captor.
2.4 Installation of Type 3202.30 with Mounting Flange
Drill 21 mm hole and 4 screw holes in wall of air-duct. Secure the mounting
flange with the 4 screws provided. Push vent-captor into duct and secure by
tightening the locking screw on the side of the flange. Sealing hp on flange
provides secure tiffing. Alternatively a PC 21 connector may be used
(see “items delivered“) Metal PC 21 tiffings are modified by the manufacturer.
ModiFication is indicated by a ‘1 on the fiffing‘s hexagon nut.

2.5 Installation of Type 3205.30
Fit the 0-ring over the front of the vent-captor and push back to the flange.
lnsert the vent-captor into the previously mounted 1“-flifing and secure with the
union nut provided. The fitting (available as separate accessory) is designed to
ensure the optimal insertion depth of the vent-captor.
2.6 Powering Up
Connect the vent-captor to 24 V DC as in connection diagram and wait approx.
5 minutes before commencing adjustment.
3.0 Initial State
3.1 The zero point potentiometer P2 s adjusted ex works to 4 mA.
3.2 The range potentiometer Pl is adjusted to the extreme clockwise position.
3.3 Where ex works adjustment of measurement range has been requested,
both potentiometers are seated with silicone. Adjustment is carried out under
manufacturer‘s test rig conditions. Under different installation conditions on
site, deviations in output signal may be possible.
N.B. 18-turn potentiometers are employed with no mechanical end point.
