10. Set the value for calibration point 2.
This parameter defines the known load on the scale in the higher calibration point.
Press
+
to get the parameter ‘Value cal. p.2’ displayed.
Capacity
500.00
kg
The displayed parameter value is the load on the scale that was set for
the higher calibration point in the last calibration.
Press ENTER.
Value cal. p.2
XXXX.XXX kg
Actual measurement value for the scale is displayed (as a ‘live’ weight value)
with a cursor and one decimal more than what is set in parameter ‘Resolution’.
Load the scale with known weights to at least two thirds of the scale capacity.
Press ENTER again to make editing possible.
Value cal. p.2
+0500.00 kg
The displayed parameter value is the value for calibration point 2 from the last
calibration with leading sign and a cursor.
The parameter value can be edited, according to point 6. on page 9 (numerical
parameter), to correspond to the actual load of known weights on the scale.
Press ENTER for 2 seconds.

Value cal. p.2
XXX.XX kg
Editing is finished and the load that is set for the higher calibration point is displayed
without cursor.
11. Read the transducer signal for calibration point 1 (read only).
By installation later of a replacement instrument, it is useful to know
the value of the transducer signals for the two calibration points.
Press
+
to get parameter ‘Transd.sign. p.1’ displayed.
Transd.sign. p.1
X.XXXXX mV/V
Make a note of the parameter value in the Quick set-up list, appendix 1.
