Belt tension checking tool
A : Sensor
B : Display
C : Connecting lead
D : Calibration checking blade
Principle
Via the pressure piece button (1), the pressure
piece (2) and the external pads (3), the sensor ap-
plies a constant slack to the belt.
The reactive force of the belt is measured using a
test unit (4) fitted with stress gauges.
The pulling of the gauges creates a variation in
their electrical resistances. Once converted by the
equipment, this variation is displayed in SEEM
units (US).
Calibration of the equipment
The equipment is calibrated at the factory, howe-
ver, this calibration must be checked every six
months.
Procedure
Setting zero:
- switch on the equipment (button E) with the
pressure piece button (1) head down,
- if 0 is displayed, do not adjust anything,
- if there is no display, check the charge of the
equipments 9 volt battery,
- if a value other than 0 is displayed, operate
screw (F) until 0 is obtained .
