CAUTION
Keep in mind that in the "Calibration with sample weight" mode, using the "Manual Resolution", the
correct sample weight value may not be perfectly represented:
For example, you have:
Cell full scale 15000 g
Sample weight 14000 g
Manual Resolution 1.5 g
The value of the sample weight (14000 g) cannot be represented with the resolution in 1.5g steps
(14000/1.5g = 9333.333 is not an integer value) so it will be represented as: 9333*1.5g = 13999.5g
To avoid this effect, use a resolution that allows the value to be represented (for example 1g or 2g).
DIGITAL INPUT/OUTPUT SELECTION
It selects whether the Z-SG2 digital channel is configured as an input or an output.
DIGITAL INPUT CONFIGURATION
If the digital channel is set as an input, it is possible to select its behaviour:
10.2.12.1.
ACQUIRES THE TARE
In this mode, if the digital input is activated for a time longer than 3 seconds, a new tare value is acquired (in
RAM, then it is lost upon restart). It is equivalent to sending the command 49594 (decimal) in the command
register (see chapter 16.6).
10.2.12.2.
EXTERNAL DIGITAL INPUT
In this mode the status of the digital input has no effect other than the display of the status in the Modbus
STATUS register.
DIGITAL OUTPUT OPERATION MODE
If the digital channel is set as an output, you can select its behaviour:
10.2.13.1.
CELL FULL SCALE
In this mode the output is activated when the gross weight reaches the full scale.
10.2.13.2.
EXCEEDING THE THRESHOLD AND STABLE WEIGHING
In this mode the output is activated when the net weight exceeds the set threshold and the stable weighing
condition is verified.
