EDIT_NAME
Enter a 10-digit name in any combination of symbols and
alpha or numeric characters.
SELECT MEASURE
Choose from Conductivity, Resistivity, TDS, or Salinity.
Default: Conductivity
MEAS UNITS
Choose from the displayed units (dependent on the
parameter selected in the Set Parameter menu)
TEMP UNITS Select Celsius or Fahrenheit. Default: Celsius
DISPLAY FORMAT
Choose from the presented options to set the display
resolution.
FILTER
Average the measurement over time by entering a number
between 0–60. Default is 0.
LOG SETUP
Choose from Sensor Interval or Temp Interval. If the interval
is enabled, choose from the displayed options to specify the
frequency to log the sensor or temperature reading. Default is

Set TDS factor. Default is 0.49 ppm/µS.
CELL CONSTANT
Choose Select Cell K to choose a nominal cell constant value
from the displayed options that is close to the “K” value
provided with the sensor. Then choose Set Cell K to enter the
specific “K” value supplied with the sensor. Entering the “K”
value eliminates the need for calibration until the sensor is
replaced and sets the analyzer measurement range to
correspond to the specified cell constant.
T–COMPENSATION
The factory default for temperature compensation is linear
with a 2.00% per °C slope and a 25 °C reference
temperature. The default settings are appropriate for most
aqueous solutions. To enter different slope and reference
temperature values for an uncommon solution, access the
menu options described below.
LINEAR: Recommended for most applications. Confirm to
change the slope or reference temperature.
AMMONIA: Not available for TDS. Contact Technical Support
for application specific information and assistance.
NATURAL WATER: Unavailable for TDS. Contact Technical
Support for application specific information and assistance.
USER TABLE: Use to configure a temperature compensation
table by entering up to 10 x-axis parameters and 10 y-axis
parameters. Contact Technical Consulting Services for
additional information and assistance.
TEMP ELEMENT
Select the temperature element type (100PT, 1000PT
(default), or manual) then choose Select Factor to enter the
specific “T” Factor supplied with the sensor.
AC FREQUENCY
Choose 50 or 60 Hz depending on the power line frequency
for optimal noise rejection. Default is 60 Hz.
DEFAULT SETUP Reset the configure settings to the factory defaults.
