Step 

 

 

 

L   0.0

 To enter low-cut to flow rate. It forces display to zero and 

analog output to 4 mA. 

 

Low-cut shall not be used on this application, constant flow rate 
shall be maintained. 

 

Press Up or Down arrow until 0.0 is selected. 

 

 Press and release M button to select and move to the next step. 

 
 

 

 
 
 
 

Step 

 

 

A    0.0  

To enter analog output zero reference corresponding to 4 

mA. 

 

The operational range is from 0 to 88 GPM of water. Therefore, 
select 0% FS or 4mA analog output. 

 

Press Up or Down arrow until 0.0 is displayed. That, is the analog 
output at 0% FS (4mA at 0 GPM of water).  

 

Press and release M button to select and move to the next step 

 

 

 
 
 
 

Step 

         
              

  _ _ _ _ 

 

A 100.0 

To enter span analog output reference corresponding to 20 

mA. 

 

The operational range is from 0 to 88 GPM of water. Therefore, 
100% full span is selected as the span or 20 mA analog output. 

 

Press UP or Down arrow until 100.0 is displayed. That, is the analog 
output at 100% FS (20mA at 88 GPM).  

 

Press and release M button to select and move to the next step. 

 

 

 
 
 

Step 

 
 

 

U    n̅ in

 To enter time factor. When flow rate is GPM, minutes shall 

be selected as the same time factor. 

 

Press UP or Down arrow until “n̅ in” is displayed. That, is the time 
factor corresponding to minutes.  

 

Press and release M button to select and move to the next step. 
 

 

 
 
 

Step 

10 

 

U _  _ 1

 To enter Flow rate volume factor. When flow rate is GPM, 1 

shall be selected to match flow factor units of gallons X1. 

 

Selectable options 1,10, 100 and 1000. 

 

1 shall be selected since the arbitrary units are in gallons. 

 

Press UP or Down arrow until “1” is displayed. That, is the unit factor 
corresponding to gallons.  

 

Press and release M button to select and move to the next step.
