SPECIFICATION
The analog output provides an isolated 4-20 mA or 0-10 VDC analog signal. The
analog output uses a 16-bit D/A converter for a very precise output.

properly.
ANALOG OUTPUT CONFIGURATION
The output signals will be at the lower limit (0 VDC or 4 mA) when the value
represented is at the zero value. When the value reaches full scale value, the
output signal will increase to the high limit (10 VDC or 20 mA). Any value between
zero and full scale value will be represented as a percentage of the output
proportional to the percentage of the value.
The ABS (absolute) displayed weight is used when material is being transferred
off of a scale in Net mode. In this case, the displayed weight will be negative, but
the analog output signal will use its absolute value. The output signal will increase
as the absolute weight value increases.
The selection of Source and Output Type determine the analog output when the
scale is under load or over load. Refer to the table below:
Source = Displayed Weight, Output Type = 4-20 mA

When the displayed weight (gross or net) drops below zero,
the analog signal keeps decreasing. When it reaches the
under load point, or it is lower than the lower limit of analog
signal range, the analog output will switch to approximately 0
mA immediately. In this case, the output remains 0 mA, or it
will output correctly.
When the displayed weight (gross or net) exceeds the over
load,
analog signal keeps increasing. When it reaches the over load
point, or it is higher than the higher limit of analog signal range,
the analog output will switch to approximately 24 mA
immediately. In this kind of situation, the output remains 24
mA, or it will output correctly.
