Note:
For calibration of the measuring system, please refer to the manual of the
corresponding indicator.
When using Minebea Intec devices, we recommend to always run the "SmartCalibration"
irst.
This allows all required values to be extracted from the supplied Calibration Certiicate.
- The "Hysteresis correction values for Smart Calibration" listed on the Calibration
Certiicate are entered for [Correction A] and [Correction B] under [Hysteresis errors]-
[speciied] in the indicator.
If the values are not found in the Calibration Certiicate, enter "0" as a value.
-
The value listed under "Output at max. capacity" on the Calibration Certiicate is
entered in the indicator under [LC rated output].
-
The value listed under "Output impedance" on the Calibration Certiicate is entered in
the indicator under [LC output impedance].
By performing these steps, a logical and highly accurate reading (normally higher than
0.1%) is generated before the scale is even loaded for the irst time.
To distribute the load over the load cells as evenly as possible, height adaptation is
required in systems with more than 3 load cells prior to calibration.
Procedure:
1. Place the dead load (e.g. empty vessel) onto the load cells of the scale structure.
2. Energize the load cells in parallel with a stabilized voltage (e.g. 12 V DC).
3. Measure the output voltages of each individual load cell by means of a digital
voltmeter and compare the individual values.
Given deviation between the output voltages of the load cells, the load on the
load cell with the lowest output voltage must be increased by putting shims
between mounting plate and weighing construction.
4. Lift the weighing object immediately beside the afected load cell.
5. Place sheets of metal from the set of metal sheets PR 6061/05S (also refer to
Chapter 12.5) between adapter plate and scale structure.
6. Measure the output voltages of the load cells again and adjust the height of this load
cell or of another one.
