3.2 - CALIBRATION OF THE DISTANCE POTENTIOMETER
- Remove the weight shelf and refit the tip on the gauge rod.
- Back-off the screws fastening the pulley on the potentiometer shaft.
- Select on the FUNCTIONS MENU (
CONTROL OF THE FUNCTIONS MENU
) → SET UP → AUTODIAGNOSTIC
(
SELF-DIAGNOSTICS
)
- Scroll until the wording (diS) appears on the left display while a number appears on the right display, which varies
when the distance gauge is moved and represents a reference for calibrating the potentiometer.
- With the gauge fully retracted, turn the potentiometer shaft keeping the pulley still until a number between 50 and
100 is read.
- Decrease by two numbers, then retighten the screws to secure the pulley on the shaft.
Carry out the DISTANCE GAUGE SET UP (
RIM DISTANCE GAUGE
);
3.3 - CALIBRATION OF THE DIAMETER POTENTIOMETER
- After
CALIBRATION OF THE DISTANCE POTENTIOMETER
press
- The wording [dIA] appears on the left display, a number appears on the right display, which varies when the gauge
is turned and represents a reference for calibrating the potentiometer.
- Remove the diameter gauge from the gauge rod after backing off relative screw.
- Slightly pull out the gauge rod and rest its stop on the machine shaft in external position near the base.
- Turn the potentiometer shaft until a number between 50 and 100 is read, then place it back in its correct work
position.
- Lock the potentiometer with relative set screw
- Carry out the DIAMETER GAUGE SET UP (
DIAMETER GAUGE
)
3.4 - CALIBRATION WIDTH SONAR (OPTIONAL)
- After
DIAMETER POTENTIOMETER CALIBRATION
press .
- Place a flat surface at least 12 cm from the width Sonar and check that there are variations in the number displayed.
- If on control, after having performed calibration, a measurement inaccuracy is found greater than 1/2”, repeat the
calibration modifying the distance value between the distance gauge and the sensor (tolerance ± 1" from the measu-
rement found manually) until a correct width value is obtained.
