NOTE:
These values do not
affect the low or the
high set point limit
for process alarms.
Range Low 1 and Range High 1
Select the low and high limits for input 1. These prompts limit the
adjustment range for the set points. The default values are the same as
the limits of the sensor you selected by setting the input 1 DIP switch and
selecting a value for Input 1 [`In1].
• Process inputs are scaled by these values. Range high is the value dis-
played when the maximum process signal is present at the input. Range
low is the value displayed when the minimum process signal is present
at the input.
Example: Set [`In1] to [4-20]mA.
Set [`rL1] to [`100].
Set [`rH1] to [`500].
A 4mA input will display [`100].
A 12mA input will display [`300].
A 20mA input will display [`500].
• The low and high values of each sensor type are listed on the specifica-
tions page of the Appendix.
• Choose between Fahrenheit and Celsius at the [`C_F] prompt in the
Global Menu.
[`rL1] [`rH1] These prompts always appear.
