Andur on "paenduva varre"otsas. Pane pilt manualist mis puudutab rihma pingutamist.
Referentspunktide all pean silmas rihma jooksva meetri kaalu, vajalikku pinget rihmas, omaresonantsi
vajaliku pinge juures.

Manual ütleb nii:

Do NOT attempt to adjust belt tension on a hot engine. Carry out the following procedure only at an engine (ambient) temperature of between 15-25°C.
If the camshaft drive has just been reassembled, rotate the engine in the normal direction of rotation (clockwise viewed from in front) several times before setting at TDC. Use the timing marks and pointer on the fly-wheel rim and clutch housing aperture viewable after removing the protective rubber grommet in the top of the clutch housing.
To check/adjust belt tension:1. Remove the 4 spark plugs, and rotate the crankshaft clockwise until the crank pulley notch aligns with the 30° BTDC front cover mark. The timing dots on the inlet and exhaust cam pulleys should be towards the centre, but not aligned. Rotate the crank a further 360° if necessary.
2. Measure the timing belt frequency using the Clavis gauge between the auxiliary shaft and inlet cam pulleys (NOT on any other belt run). When tapped with a suitable instrument (e.g. screwdriver) the meter should read: Specification = 100 to 110 Hz
3. If necessary, slacken the tensioner clamp bolt and turn the eccentric hub as required to adjust the belt tension (turn counterclockwise to increase tension). Tighten the clamp nut to 34-41 Nm. Rotate the crankshaft 720° clockwise and re-check belt tension.
Note: Do not turn the crankshaft backwards (counterclockwise) at any stage of the procedure.

Seega rihma jooksva meetri kaalu peab ise välja arvutama. Pingutatud rihma sagedus peab jääma vahemikku 100-110Hz. 

   
Mõõtekoht tulemüüri poolt vaadatuna mahatõstetud mootoril. Mõõdetav mootor autol peal ja lähima rihmarulliku ja tulemüüri vahele lääb ehk 5-6cm vaba ruumi. Mõõtmiseks tuleb termostaadi koja pealt jahutusveetoru ja sellega ühendatud lõdvikud eemaldada, sest jahutusveetoru jookseb üle rihma täpselt mõõtekoha pealt. Ehk siis mootor jahutusveest tühjaks.

   
Sama mootor vaadatuna mootoriruumist (auto keskmootoriga). Kollane nool viitab mõõtekohta.
