C66 Display calibration values as measured with C code 83/115 (virtual dimensions)
Options: None
Special function: None.
Description: Values for both transducers in mm. Reference mark is the zero reference of Geodata
Values for both transducers in mm.
Reference mark is the zero reference of Geodata (right-hand edge of machine cabinet for geodata)
1. Field : Rear transducer: 262 - 272
2. Field : Front transducer: -1500 to -10000
Comments: The shown values are those calculated in the latest calibration performed.
C67 Display phase stability of the vpm system as measured with C code 83/115
Options:
Press “RETURN” key to switch over between
- the distance-dependant phase shift of the rear transducer and
- the phase shift between the rear and front transducers
Special function: None.
Description: The distance-dependant phase shift of the rear transducer is indicated rst.
Comments: The shown values are those calculated in the latest calibration performed.
C71 Display angular deviation of VPM system as measured with C code C83 / C115
Options: Press “RETURN” key to switching over between rear and front transducers
Special function: None.
Description: Reading on display machine must be:
Rear transducer 178-182
Front transducer 358-002
Comments: The shown values are those calculated in the latest calibration performed.
C72 Measurement of angular deviation
Options: Press “+/-” key to switching over between rear and front transducers.
Special function: None.
Description
1. Remove wheel or test rotor and centering cone from the adaptor.
With power clamp fi t the spacer bushing, the medium centering cone and the clamping sleeve
without clamping head onto the bushing and carry out clamping operation.
Set code C72.
2. Press low the wheel guard in order to initiate temporary compensation of unbalance.
3. Insert the user calibration weight into the adaptor " ange so that it extends to the left and
ow the wheel guard.
4. Insert the user calibration weight into the adaptor " ange so that it extends to the right and
ow the wheel guard.
After three measuring runs the angle for the rear transducer is read out.
The step numbers are indicated on the left display:
angle = arg(2
