Adjust the LCD contrast for best viewing.  A setting of 1 is lower contrast, 5 is higher.  In 

general, select lower contrast if the display is in warmer ambient surroundings.  

 

 

 

 

 

 

Set the decimal to the best resolution for your application.  The display will automatically 

scale down  to this restriction.  Select *****., ****.*, ***.**  **.***  or *.**** .

OFF provides the most instantaneous response to process changes.  Select LOW (4 sec) 

or HIGH (8 sec) averaging if your process experiences frequent or extreme 

fl

 uctuations.

Adjust the minimum and maximum current output. The display value represents the 

precise current output. Adjustment limits:                                                                              

                                          •  3.80 mA < 4.00 mA > 5.00 mA                                                  

                                          •  19.00 mA < 20.00 mA > 21.00 mA                                           

 Use this setting to match the system output to any external device.     

 

Select ºC or ºF.

Set the percent change in Conductivity caused by a 1ºC change in temperature.  May be 

from 0.00 to 10.00.

Active HIGH: This setting is used to turn a device (pump, valve) ON at the setpoint.          

                                                                                                                                             

 Active LOW:  This setting is used to turn a device OFF at the setpoint. 

 

 

Press UP and DOWN keys to manually order any output current value from 

3.8 mA to 21.00 mA to test the output loop. 

Press UP and DOWN keys to manually toggle the Open Collector output state.
