Description

Contrast:

3 >

Adjust the LCD contrast for best viewing. A setting of 1 is lowest contrast, 5 is highest.  Select 
lower contrast if the display is in warmer ambient surroundings.

Cond Decimal:

****.* >

Set the decimal to the best resolution for your application. The display will automatically scale 
up to this restriction. Select *****., ****.*, ***.** **.*** or *.****.

Averaging

Off >

OFF provides the quickest output response to changes in temperature. Longer averaging 
period produces more stable display and output response.

Temp Display

°C >

Select temperature units: ºC or ºF.

Temperature Comp %:

2.00 >

Set the percent change in Conductivity caused by a 1 ºC change in temperature. May be from 
0.00 to 10.00.

Loop Adjust

4.00 mA 

>

Adjust the minimum and maximum current output. Use this setting to match the system output 
to any external device. 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

Loop Adjust

20.00 mA 

>

Test Loop:

 

>

Press 

 or 

 keys to manually order any output current value from 3.6 mA to 21.00 mA to test 

current loop output.

Test Relay 1:

 

>

Press 

 or 

 keys to manually toggle the state of Relay 1.

Test Relay 2:

 

>

Press 

 or 

 keys to manually toggle the state of Relay 2.
