High Reading
Use this menu to enter the input level that corresponds to the high
process value you entered in the previous menu. For linear inputs, the
high reading is a percentage of the full scale input range. For pulse
inputs, the high reading is expressed in Hz.
The 100% full scale input value is 60 mV for the linear input type.
Selectable range: Any value between -99.9 and 110.0. For pulse input,
the range is 0-2000 Hz, and the default is 1000 Hz.
Low Process Value
Use this menu to set a low process value for input scaling purposes. The
low process value and the low reading value together define one of the
points on the linear scaling function's conversion line.
Selectable values: See table on previous page.
Low Reading
Use this menu to enter the input level that corresponds to the low
process value you selected in the previous menu. For linear inputs, the
low reading is a percentage of the full scale input range. For pulse
inputs, the low reading is expressed in Hz.
The full scale input range for the linear input type is -10 to 60 mV,
which corresponds to -16.6 to 100.0%.
Selectable range: Any value between - 99.9 and 110.0. For pulse
inputs, the range is 0-2000 Hz, and the default is 0.
