4.4 WATLOW Series 988LF Users Manual Setup Menu, Chapter 4
Range Low and Range High
Select the low and high range 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 DIP switch and
selecting a value for Input [`In1].
• Process inputs are scaled by these values. Range high is the value
displayed 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
Setup Menu.
[`rL1] [`rH1] These prompts always appear.

NOTE:
These values do not
affect the low or the high
set point limit for
process alarms.
NOTE:
When high impedance
[`0-50] is selected for
Input 1, the range high
for both
[``°C] and
[``°F] can be extended
to [9999] . The range
low, when [``°C] is
selected, can be ex-
tended to
