Siebert S302 Series - Setting Display Settings During Initialization (Numeric Mode Only); Offset, Scale Factor, and Divisor

BAL S302 PFN RT 1.00 17/27
9 Setting the display settings during initialization (numeric operation mode only)
Initialization parameters are loaded to the display once. They cannot be changed during operation.
Decimal Dots
Decimal points
Decimal Dots (property number 1)
The number and position of the decimal points can be defined with the help of a bit mask. For
example, multiple decimal points can be used to display a date or codes.
A set bit corresponds with a set decimal point.
The least significant bit corresponds to the decimal point of the least significant digit. If, for example,
the number '1234' is to be displayed with a decimal point between the 100th and the 10th digit, the bit
mask must be set to the value '0x04' and '12 .34 'appears on the display.
Offset, scale factor (multiplier) and divisor
(property numbers 2, 3 and 12)
The formula that can be stored in the display allows you to display values in other units, such as
degrees Fahrenheit in degrees Celsius, kilograms in tons, miles in kilometers, or adding an offset.
This initialization parameter consists of the values offset, scale factor (multiplier) and divisor.

The calculation is based on the following linear function:
Displayed value = offset + scale factor (multiplier) / divisor x sent value
As a scale factor, integers are possible. Other factors can be formed by a combination of 'ScaleFactor'
and 'Divisor'. For example, a multiplication with '13, 42 'can be generated by the scale factor' 1342
'and divisor' 100 '.
Threshold values
Range (property numbers 4 und 5)
This initialization value defines the upper and lower thresholds at which the display automatically
changes its display attribute.

SINT32
-2147483648
No threshold values are defined in the delivery state. The default value -2147483648 (hex:
16#80000000) commands this.
If a value is received outside the defined thresholds, the display automatically changes from 'standard'
to 'out of range'. As soon as a value is received within the defined limits, the display returns to
standard.
Example: For a temperature value display, the display should change its display mode, both when the
temperature falls below 0 degrees Celcius and when it exceeds 100 degrees Celcius. For this, the
values Upper bound = 100 and Lower bound = 0 must be entered.
Flags (propüerty
Flags (property number 6)
In this initialization value (type INT16), display properties are set.
See chapter Flags.
