5.2.5 Checking the calibration of the channels
The load values displayed by the readout unit are conditioned by the calibration
coefficients.
The calibration is required to perform periodical checks (e.g. preventive maintenance),
when attaching the
WIZARD 2 to the transducers of an existing machine and/or when a
new transducer is connected to it (e.g. replacement of a defective transducer).
The main steps of the procedure can be summarized as follows:
1.
Calibration verification; if the unit is within the limits of the standard, the procedure
ends, otherwise proceed with step 2;
2. Calibration of the unit (e.g. adjustment of the force measurement device connected to
the unit);
3. New calibration verification (repeat step 1).
Steps 2 and 3 above are required if the unit is not within the limits indicated by the
standards.
Step 1 above consists of:
o
Application of several levels of force (at least 5) ranging from 20% to 100% of the
full scale of the frame;
o
For each level of force, compare the measured value by
WIZARD 2
with the values
measured by a calibrated external device (e.g. a loadcell with relevant readout unit).
The verification and calibration are carried out by activating the
CALIBRATION option
from the
MAIN MENU
.
WARNING:
The CALIBRATION menu is reserved to the authorised service personnel and should
only be entered when the calibration needs to be changed. CONTROLS will not be
responsible for any damage caused by improper setting of these parameters. Warranty
