5.4 Initial start-up
A warm-up time of 5 minutes stabilises the measured values after switching on.
The accuracy of the balance depends on the local acceleration of the fall.
Please be sure to observe the information in the chapter on adjusting.
5.5 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated – in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location (
only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out during the initial start-up, after change in lo-
cation and variation of surrounding temperature. It is also recommendable to adjust
the balance periodically during weighing operation in order to obtain exact measured
values.
5.6 Adjusting
Using a precision weight, the accuracy of the balance can be checked at any time
and adjusted.
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 5 minutes is recommended for stabilisation.
Operation Display
Turn balance on using ON/OFF button
Hold down TARE button for 3 seconds
The weight value for adjusting the scales will appear in the
display.
Place the required adjustment weight on the weighing plat-
form (see section 1, “Technical data“)
Shortly afterwards, this will appear:
If adjustment has not worked correctly or if the wrong ad-
justment weight was used then this will be displayed:
In this case switch the power off and on and repeat the
adjustment process.
Remove the weight from the weighing platform and the
display will automatically return to normal weighing mode.
Adjustment has been successfully completed.
