Menu ‘Scale 1 Calibration’
The Scale 1 Calibration menu is found after the last parameter in menu Scale. Here
only scale 1 menu is shown. Note that the scale number is shown as a prefix to the
parameter name, here ‘1:’
1:Calibration Type
Data Sheet
Deadweight
Table
<Data Sheet> Defines the type of calibration to be performed.
A new calibration is initiated as a ‘Calibration type’
is selected.
Data Sheet: Data sheet calibration is easy to use and
doesn’t demand any reference equipment, except data
from the transducer data sheets.
Deadweight: Deadweight calibration is normally
the most accurate calibration type. It requires known
weights to at least 2/3 of the wanted measuring range.
Table: Table calibration is used to enter recorded values
from a previous calibration into a replacement
instrument.
Data sheet calibration related parameters
1:Conversion Factor
Range:
0.01 to 100
<9.80665> Defines the relationship between a measured value
expressed in data sheet unit and expressed in the
selected measurement unit.
1:Number of Transducers
Range:
1 to 4
<3> Defines the number of transducers and fixed support
points in the scale installation. All transducers must have
equal rated load.
If the total number is over 4: enter 1 here!
1:Rated Load
Range:
1 to 999999
Unit:
Data sheet unit
<2000.00> Defines the rated load for one transducer, expressed in
the data sheet unit. The value is specified in
the transducer data sheet.
NOTE! If the data sheet value is 5 kN, the parameter
should be set to 5000 (N).
If the total number of transducers and fixed supports is
over 4: multiply that number with the rated load for one
transducer and enter the result here!
