The “ANS” adjustable support (0TEL310ANS0) has been developed to support and fix the “SUS” optical sensor unit (0TEL310SUS0) of the new TEL-310S telecoordinometer. The support is fixed to the wall through two M16 threaded bars, of 370 mm. length (supplied). Once the “SUS” optical sensor unit is fixed to the support, it is possible to adjust the settings in order to place the pendulum’s wire in the chosen position within the instrument measuring range.
