Q45C2 2E Conductivity System  

 

Part 4 – Configuration

If Relay B Mode is set to 

CON

 (see 

Relay B Mode

), then 

Relay B will function identically to Relay A.  Relay B settings 
appear in the CONFIG menu list automatically.

 

 
 

 
 Contrast 

This function sets the contrast level for the display.  The 
custom display is designed with a wide temperature range, 
Super-Twist Nematic (STN) fluid.   

 
 

 

The STN display provides the highest possible contrast and 
widest viewing angle under all conditions.  Contrast control 
of this type of display is generally not necessary, so contrast 
control is provided as a means for possible adjustment due 
to aging at extreme ranges.  In addition, the display has an 
automatic temperature compensation network.  Press 
ENTER to initiate user entry mode, and the value will flash.  
Use arrow keys to modify the value; range is 0 to 8 (0 being 
lightest).  Press ENTER to update and store the new value. 

 

 

Display  

This function allows the user to change the measurement in  
the primary display area.  The user may select between 
conductivity, sensor temperature, or output current.  Using 
this function, the user may choose to put temperature in the 
main display area and conductivity on the secondary, lower 
line of the display.  Press ENTER to initiate user entry mode, 
and the entire value will flash.  Use the UP arrow key to 
modify the desired display value.  Press ENTER to store the 
new value. 

 

 Temp 

Units 

 

This function sets the display units for temperature  
measurement.  Press ENTER to initiate user entry mode, 
and the entire value will flash.  Use the UP arrow key to 
modify the desired display value.  The choices are °F and 
°C.  Press ENTER to store the new value. 

 
 Temp 

Input 

 

This function allows the user to manually lock the  
temperature at a fixed value of 25 °C.  Once locked at 25 °C, 
a small 

m

 appears next to the temperature value on the 

lower line of the display to indicate to the user that the 
system is in manual lock mode.  All temperature 
compensation is defeated when in the manual lock mode.  
This mode is provided for users requiring uncompensated 
conductivity readings.  Press ENTER to initiate user entry, 
and the entire value will flash.  Use the UP arrow key to 

*B Setpoint 
*B Hysteresis

 

*B Delay

 

*B Phasing
