Auto Zero Tracking
AZT automatically re-adjusts the scale to zero for compensating defined small deviations around the center of
zero. AZT only works within the defined zeroing range and stops working if this range is left.To avoid unwanted
zeroing this parameter should be disabled or carefully set up in applications like silo weighing, tank weighing
and automatic weighing applications (Not available in Count Mode). The available AZT window values are;
Disable (default setting) ± 0,5e ± 1e ± 3e
Tare
If this function is enabled, the weight is tared when the tare command is received. Additional conditions for
taring are positive gross weight and no motion. Multi-taring is possible (Not available in Count Mode). Default
setting: „Enable‟.
Save Tare at Power Off
If this function is enabled, the tare value is stored at power off and the instrument starts up in Net mode at
power on (Not available in Count Mode). Default setting: „Enable‟.
5.5.2. Scale Build and Calibration
Scale build, operation mode selection and scale calibration is performed in the calibration tab of xFace as
shown in figure 5.7. Please follow the procedure in the sequence as described in the following chapters.
Figure 5.7
– MCS-08AD Setup Parameters
Mode: This block allows the user to select the operation mode and polarity.
Write to Instrument: Click this button to save the operation mode and the polarity.
Scale Build: Here you define the capacity, the increment and the unit of the scale
Calibration with Test Weight: This block allows the user to calibrate with test weights.
ECal Calibration: This block allows the user to calibrate without test weights.
Calibration Coefficients: This function allows the user to restore a calibration if the calibration
coefficients have been noted before.
For entering the parameter values enter the setup tab, adjust the parameter settings and then write this data to
the A/D Converter. After changing parameter settings the instrument always requires a re-calibration.
Mode selection
MCS-08AD modules have three operation modes which are:
Count Mode: Filtered and normalized ADC count data will be transmitted in this mode. The
calibration is performed at the PLC, if any.
