• Deadload: calculation of the equivalent input voltage in mV/V
The input voltage equivalent to the deadload in mV/V is calculated as follows:
cells) load of no. * load (nominalcapacity cell load
[mV/V]CAvr y sensitivit cell load * (weight) deadload
= [mV/V] deadload
Unless the deadload is known from the very beginning, it must be estimated, and this estimation must be used
to calculate the deadload in mV/V. The subsequent zero correction can be used to redetermine the
⇒ deadload subsequently (hopper is empty). See 'Subsequent zero correction' in 'Weighing point calibration
with weights.'
5.6.7.1 Calibration without weights
Proceed as described in points 1. to 7. of the 'Weighing point calibration procedure'. This is followed by the
actual calibration:
1. The following command line is displayed in the calibration mask:
Deadload
Calibration by mV/V
Enter deadload mV/V, Q to quit, S to skip: _
Enter deadload mV/V enter deadload in mV/V
Q to Quit + press Enter [] and quit without doing anything
S to Skip + press Enter [] and skip the tare entry
2. Enter the deadload in mV/V
- Enter the deadload with comma (or point)
- Complete by pressing the Enter key [
↵]
• The instrument evaluates the data.
Now, the following command line is displayed in the weighing point calibration mask:
Setting deadloads … system saves the data, subsequently:
Setting deadloads … Status OK message is displayed during approx. 2 s
• The weight display does not change.
3. The following command line is displayed in the calibration mask: Span
Calibration by mV/V
Enter span mV/V, E to exit: _
Enter span mV/V Enter the span in mV/V
E to Exit + Enter key [↵] no entry/ terminate calibration
4. Enter the span in mV/V
- Enter the span with comma (or point)
- Finish the entry by pressing the enter key [
↵].
• The instrument evaluates the data.
Now, the following command line is displayed in the weighing point calibration mask:
Setting span … the system saves the data. subsequently:
Setting span … Status OK the message is displayed during approx. 2 s
Calculating test … the system calculates the test value
Calculating test … Status OK
• The new gross weight is displayed: 0027 kg . Subsequently, the standard command line is displayed:
