Operation
User navigation
Refer to the User interface and navigation section of the controller documentation for keypad
description and navigation information.
Sensor configuration
Contacting conductivity sensor configuration
Use the CONFIGURE menu to enter identification information for the sensor and to change options
for data handling and storage.
1. Push the menu key and select SENSOR SETUP>[Select Sensor]>CONFIGURE.
2. Select an option and push enter . To enter numbers, characters or punctuation, push and hold the
up or down arrow keys. Push the right arrow key to advance to the next space.
Option Description
EDIT NAME Changes the name that corresponds to the sensor on the top of the measure screen.
The name is limited to 16 characters in any combination of letters, numbers, spaces or
punctuation. Only the first 12 characters are displayed on the controller.
SENSOR S/N Allows the user to enter the serial number of the sensor, limited to 16 characters in any
combination of letters, numbers, spaces or punctuation.
SELECT MEASURE Changes the measured parameter to CONDUCTIVITY (default), TDS (total dissolved
solids), SALINITY or RESISTIVITY. All other configured settings are reset to the
default values.
Note: If SALINITY is selected, the measurement unit is defined as ppt (parts per
thousand) and cannot be changed.
DISPLAY FORMAT Changes the number of decimal places that are shown on the measure screen. When
set to auto, the number of decimal places changes automatically with changes in the
measured value.
MEAS UNITS Changes the units for the selected measurement—select the unit from the list
available.
TEMP UNITS Sets the temperature units to °C (default) or °F.
T-COMPENSATION Adds a temperature-dependent correction to the measured value:
• NONE—Temperature compensation not required
• USP—Set the alarm level for the standard USP definition table
• ULTRA PURE WATER—Not available for TDS. Set the compensation type
according to the sample characteristics—Select NaCl , HCl, AMMONIA or ULTRA
PURE WATER
• USER—Select BUILT IN LINEAR, LINEAR or TEMP TABLE:
• BUILT IN LINEAR—Use the pre-defined linear table (slope defined as 2.0%/°C,
reference temperature as 25 °C)
• LINEAR—Set the slope and reference temperature parameters if different from
the built-in parameters
• TEMP TABLE—Set the temperature and multiplication factor points (refer to
Configure user tables on page 11)
• NATURAL WATER—Not available for TDS
CONFIG TDS TDS only—changes the factor that is used to convert conductivity to TDS: NaCl
(0.49 ppm/µS) or CUSTOM (enter factor between 0.01 and 99.99 ppm/µS).
CABLE PARAM Sets the sensor cable parameters to improve measurement accuracy when the sensor
cable is extended or shortened from the standard 5 m. Enter the cable length,
resistance and capacitance.
