Principle
The sensor, through the adjusting button (1), the
pressure device (2) and the outer lugs (3), applies a
constant force to the belt.
The reaction from the belt is measured using a
test piece (4) fitted with strain gauges.
Any movement on the gauges creates a variation
in their electrical resistance. This variation, once it
has been converted by the device, is displayed on
the display in SEEM units (US).Calibrating the device
The device is set in the factory, however it must be
recalibrated every six months.
Procedure
Resetting zero:
- switch the device on (button E) with the adjus-
ting button (1) fully screwed in,
- if 0 is displayed, do not touch anything,
- if nothing is displayed, check the condition of
the 9 volt battery in the device ,
- if a value other than 0 is displayed, adjust screw
(F) until 0 is displayed.

Checking the calibration
Switch the device on (button E).
Position the calibration spring plate (Z) on the sensor as shown on the diagram (checking value engraved to-
wards the top, (A) minimum value, (B) maximum value).
Tighten the adjusting button (1) until it goes "CLICK - CLICK - CLICK".
Check that a value X between the values (A and B) (A ≤ X ≤ B) is displayed.
Note: it may be necessary to perform several preliminary tests in order to obtain the correct value.
If the correct value if still not obtained after several attempts, contact SEEM.
NOTE : each device has its own calibration spring plate and they are not interchangeable.

GENERAL INSTRUCTIONS:
- Never refit a belt which has been removed, re-
place it.
- Never retighten a belt for which the tension
reading is between the fitting value and the
minimum operating value.
- When checking, if the tension is below the mi-
nimum operating value, replace the belt.

Position the sensor of Mot. 1273.
Turn the adjusting button of the sensor until it disengages (three ’’CLICKS’’).
Tension the belt until the recommended fitting value is displayed on Mot. 1273 .
Lock the tensioner, check it, adjust the value.
Turn the crankshaft overthree times.
Check that the tension value is within the fitting tension tolerance, otherwise readjust it.
NOTE :
Never refit a belt which has been removed.
Replace the belt, if the tension is below the minimum operating tension.
Small cuts or cracks do not mean that the belt has to be replaced.
