Calibration
Calibration with test load:
Access to the parameter 301 and follow the steps below to calibrate the scale.
1. Press < Enter > at the [ 301 ] prompt to start the calibration.
2. At the [ ZEro.CA ] prompt, remove any weight on the platform, then press < Enter >.
3. The terminal automatically starts to capture zero and the [ WAıt ] message indicating
the operation is in progress.
4. After the [ Load ] prompt, the test weight value will be used for the calibration seen
on the display as [ XXXXXX ] . If the value of the test weights that will be used is
different from the value shown on the display, type the new value via < Tare > and
< Zero > keys. A minimum of 20% of scale capacity is necessary for calibration;
BAYKON recommends 50 to 100%. A calibration error is produced if insufficient
weight is used.
5. Place the test weights or another practical weight on the scale.
6. Press < Enter > to start span calibration. [ WAıt ] message will shown on the display
10 seconds while span calibration is performed.
7. The following parameter is displayed after calibration. If any, error message is
announced. (Page 45)
Note: Refer to Technical manual for multipoint calibration to correct the linearity.
eCal Electronic Calibration without test load:
The scale capacity and increment shall be entered before performing eCal.
Warning:
This parameter lets you to perform calibration without using any test weights. BX11 A/D
coefficients are adjusted in production for increasing eCal accuracy. The calibration
coefficients are calculated by scale capacity, total load cell capacity, load cell full scale
output, and estimated dead load.
Access to the parameter 313 and enter the values below as;
[LC.CAP ]
[XXXXXX]
Enter total load cell capacity via < Tare > and < Zero > keys and press < Enter > key to go
to the next step.
Example : If the weighing system has 4 pcs 1000 kg load cell, enter 4000.
[LC.oUt ]
[XXXXXX]
Enter load cell output in mV/V via < Tare > and < Zero > keys. If the weighing system has
more than one load cell, calculate the mean value of load cells outputs mV/V indicated on the
certificates of the load cells. Press < Enter > key to go to the next step.
