Preparing for Calibration

6.1

General Information

Note:

For calibration of the measuring system, please refer to the manual of the weighing
instrument.

Caution:
A warming-up time of at least 30 minutes for the load cell is required before
calibration of the weighing installation.

6.2

Mechanical Height Adaptation

To distribute the load to the load cells as evenly as possible, height adaptation is required prior to
calibration in systems with more than 3 load cells.
• Apply the dead load to the load cell (e.g.: empty vessel).
• Energize the load cells with a stabilized voltage of e.g. 12 V DC.
• Measure the output voltages of each individual load cell by means of a voltmeter and compare the

individual values.

The load applied to the weighing module weigh cell with the lowest output voltage must be increased by
inserting shims underneath.
