Hach-Lange POLYMETRON 9500 Conductivity Module User Manual - Manual (Page 10)

Option Description
TEMP ELEMENT Sets the temperature element to PT100 or PT1000 for automatic temperature
compensation. If no element is used, the type can be set to MANUAL and a value for
temperature compensation can be entered.
FILTER Sets a time constant to increase signal stability. The time constant calculates the
average value during a specified time—0 (no effect) to 60 seconds (average of signal
value for 60 seconds). The filter increases the time for the sensor signal to respond to
actual changes in the process.
LOG SETUP Sets the time interval for data storage in the data log—5, 30 seconds, 1, 2, 5, 10,
15 (default), 30, 60 minutes.
RESET DEFAULTS Sets the configuration menu to the default settings. All sensor information is lost.
Inductive 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), RESISTIVITY,
SALINITY, TDS (total dissolved solids) or CONCENTRATION. 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:
• LINEAR—Set the slope and reference temperature parameters
• NATURAL WATER—Not available for TDS or CONCENTRATION
• TEMP TABLE—Set the temperature and multiplication factor points (refer to
Configure user tables on page 11)
• NONE—Temperature compensation not required
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).
