4.3.5 Input Low/High Scale
The Input Low Scale and Input High Scale entries are used to set the input range for linear input types (VDC or
mA). The entries are not available for temperature input types since they utilize a fixed range based on the
sensor type. The input low scale value can be set from -19999 up to the high scale value. The high scale value
can be set from the low scale value up to 45536.
NOTE:
The minimum and maximum scale values are limited by the decimal point selection. For a decimal
of 0, the values are -19999 and 45536 respectively. For one decimal point, the values are -1999.9
and 4553.6. For two decimal digits, the values are -199.99 and 455.36 and for three decimal digits
the values are -19.999 and 45.536.

the main Limit Configuration screen.
4.3.7 Output 1 Function

selecting one will turn off the others. Once the desire
d function has been selected, press the “Done” button to
set the limit output function and return to the main Limit Configuration screen.
