Hach-Lange LDO Sensor - Manual (Page 9)

Operation
User navigation
Refer to the controller documentation for keypad description and navigation information.
Configure the sensor
Use the Configure menu to enter identification information for the sensor and to change options for
data handling and storage.
For information about sensor installation, refer to
Install the sensor on page 8.
Make sure that all of the Configuration menu values are correct for the application.
1. Go to MENU>SENSOR SETUP>[Select Sensor]>CONFIGURE.
2. Select an option, ENTER. The list of available options is shown in the table below.
Option Description
EDIT NAME Changes the name that corresponds to the sensor on the top of the measure screen. The
name is limited to 10 characters in any combination of letters, numbers, spaces or
punctuation.
SET UNITS TEMP–Sets the temperature units to °C (default) or °F.
MEASURE–Set the measurement units in mg/L, ppm or % .
ALT/PRESS–Set the altitude in m or ft, or set the atmospheric pressure units in mmHg or
torr. (Default value = 0 ft)
ALT/PRESS Enter the value of the altitude or atmospheric pressure. This value must be accurate to
complete % saturation measurements and calibration in air. (Default = 0 ft).
SALINITY Enter the salinity value. Salinity range: 0.00 to 250.00 parts per thousand (‰). Refer to
Enter a salinity correction value on page 10 for more information. (Default value = 0)
SIGNAL AVERAGE Set the time interval to average signal in seconds
CLEAN INTRVL Set the time interval for manual sensor cleaning in days (Default value = 0 days. A value
of 0 days disables the clean interval.)
RESET CLN INTRVL Set the time interval to the last saved clean interval
LOG SETUP Sets the time interval for data storage in the data log—0.5, 1, 2, 5, 10, 15 (default), 30,
60 minutes.
SET DEFAULTS Restores the configurable default values for the sensor. Does not change the setting for
slope or offset.
Enter the atmospheric pressure value
The factory setting for atmospheric (air) pressure is 0 ft, or sea level. To change the default value,
use the steps in this procedure. The adjustment for air pressure is entered as either elevation or as
pressure units (preferred).
Note: Accurate air pressure is critical for saturated air calibration ( Calibration with air on page 11). Use only
absolute pressure, not adjusted. If the absolute air pressure is not known, use the correct elevation for the location.
1. Go to MENU>SENSOR SETUP>[Select Sensor]>CONFIGURE>SET UNITS>AIR PRESS/ALT
UNITS.
2. Select one of the unit options listed:
Option Description
ft Feet—unit of measure for elevation
m Meters—metric unit of measure for elevation
