_________________________________________________________________________

___________________________________________________________________

A multiple turn calibrator for coarse

setting of sensitivity is placed close

to the battery contacts inside the

handle in the battery compartment.

To open the battery compartment

unscrew handle. To adjust standard

sensitivity slide external sensitivity

knob to mid position in its slot and

calibrate sensitivity trimmer inside

the battery compartment just below

the audio threshold (Pict.7). Tuning

clockwise increases sensitivity.

Make sure that detector has

operational temperature before

recalibrating coarse sensitivity

adjuster. Give at least 25 min. under

normal working conditions before

such intervention.

7. Testing before use

Take UWEX

722 C out from its carrying bag. Unscrew handle. Insert 9V battery

watching correct polarity as indicated by markings. Refit handle. To extend detector use

extension rod.

Rotate handle clockwise into ON position with white dots matching and set sensitivity

knob to required sensitivity level. During calibration the detector head must be held

approx. 1,5m away from any metal. It may be difficult to calibrate detector inside

buildings due to plenty of metal interference.

A fresh battery gives approx. audible 1 click every 3 seconds. The click rate increases

with dropping voltage. If battery power is below nominal value the detector gives an

audio alarm of low frequency (approx. 100Hz) which can not be cancelled using the

sensitivity adjuster..

In case of missing clicks or constant alarm detector is not operational. Check battery.
