Capacity : To select a new value for the scale capacity, click in the text box. Use
the keyboard to enter a new value, or use drop-down menu.
Use the drop-down menu to select the increment.
Scale calibration can be performed by using test weights or by electronic calibration.
5.3.2.3. Calibration with test weights
This calibration method performs zero and span calibrations using test weights. Test
weight value should not be less than 1/10 of the scale capacity for accurate calibration.
Figure 4.4 - Calibration with test weights
Please note that scale build values shall be entered before starting calibration.
Select Full Calibration for performing scale calibration. Click the Start button. Unload the
scale for performing zero calibration and click Yes button. The virtual display will show
[WAIT] message during zero calibration. During zero calibration the scale must be stable.
Approximately 5 seconds later, the span calibration window is displayed. Load the scale
and enter the loaded test weight value, then click OK button. The scale must be stable
during span calibration. Approximately 5 seconds later, the new calibration settings are
saved automatically.
If any error occurs during calibration, an error message warns you. Click Yes button to
reload the previous values or click No button to use the new settings.
You can adjust zero or span of your scale without performing full calibration. Additionally,
span calibration to the unloaded scale feature gives advantage to TX 2 instruments in
after-sale service.
Zero Adjustment:
If your scale has a residual zero drift, you may perform only zero adjustment. Select Zero
adjustment and press Start button. Then, the zero calibration window is displayed. Unload
the scale and click OK button. The [WAIT] message appears on the virtual display during
zero adjustment. Approximately 5 seconds later zero adjustment will be finalized.
Note: Zero adjustment is also performed over field bus commands. Refer to data structure
of related field bus.
