5.4 Sensor Setup Menu

SELECT SENSOR (if more than one sensor is attached)
CALIBRATE
AIR CAL
Perform an air calibration of the sensor (slope calibration). See
SAMPLE CAL
Enter a value for the DO concentration as determined by another sensor or independent method. The instrument
performs an offset calibration based on the entered value. See
SET CAL DEFLT
Restores the gain and offset values to 1.0 and 0.0, respectively, and restores the Sensor Cap Code to default.
CONFIGURE
EDIT NAME
Enter up to a 10-digit name in any combination of symbols and alpha or numeric characters.
ALT/PRESS UNITS
Choose pressure units in feet, meters, mm Hg, or torr.
ALT/PRESS
Enter either altitude or air pressure. Correlates to the pressure units setting. Range: –5000 to 15000
Note: The Alt/Press setting must be correct for proper measurement of % saturation and proper operation of air
calibration.
TEMP UNITS
Select Celsius or Fahrenheit.
MEAS UNITS
Select the appropriate measurement units to display. Choose from: mg/L, ppm, or percent.
SALINITY
User-entered value. Range: 0.00–250.00 parts per thousand salinity
SENSOR CODE
Enter the unique code supplied with each sensor cap. The code ensures the preprogrammed factory calibration is
adjusted for each sensor cap. The code consists of either 10-digits or 3-digits followed by a period. The period following
the three digit code must be entered to complete the code entry.
SET DEFAULTS
Resets the sensor configuration to default settings.
SIGNAL AVE
Averages readings over a specified time interval. Default is 60 sec. Increase response by decreasing the time interval.
Fastest response is at 0 sec.
LOG SETUP
Allows user to select data logging interval of DO and temperature readings.
