[1F] Enter airflow
direction sense:
A Normal sign
B Reverse sign
Selecting the Reverse sign multiplies the
value on the display by –1. Use this option if
you would like to receive positive values
instead of negative values.
[1G] Enter zero flow
cutoff :
0.0
kcfm
Zero flow cut off allows you to select a
specific range of measurements. For example
if you are working in kcfm and enter a value
of 100, and your full scale setting is 500, your
measurement range will now be 100-500
kcfm as opposed to 0-500 kcfm.
[1H] Enter instrument
full scale :
1000
kcfm
This is the full-scale reading of the instrument
in the units selected. Flow readings greater
than this will result in a “*” to appear in the
right most display indicating that you have
exceeded your full scale range.
[1I] Enter 4-20mA over
range mode:
A Saturate / Clipping
B Emit 3mA error
Selecting A, if the flow exceeds full-scale, the
mA output will saturate at 20mA. Selecting
B, if the flow exceeds full-scale, the
instrument will output 3mA indicating that
the full scale or max airflow has been
exceeded.
[1J] Obstruction/fault
timeout in minutes
(100 = disabled):
100
Obstruction/fault allows the instrument to
output the last known good reading in the
event there is something blocking the signal
between the two sensors for example a large
vehicle. The value can be selected from 0-99
minutes. Once the time has elapsed the unit
will output a 0.3V error.
[1K] Enter 4-20mA mode :
A 4mA 0% 20mA 100%
B 4mA 100% 20mA 0%
C Split mode 12mA 0%
A (Normal mode) 4mA corresponds to
minimum airflow. (20mA max)
B (Reverse mode) 4mA corresponds to
maximum airflow. (20mA min)
C (Split mode) 12mA corresponds to 0
airflow, 4mA to max negative, and 20mA to
max.
