Operation
5.5 ORP Sensor Setup Menu
SELECT SENSOR (if more than one sensor is attached)
CALIBRATE (Main Menu Item)
1 POINT MANUAL Calibration against a single known sample.
TEMP ADJUST Adjust the displayed temperature by up to ± 15 °C.
DEFAULT SETUP Restores the system to the original factory calibration.
CONFIGURE
EDIT NAME Enter up to a 10-digit name in any combination of symbols and alpha or numeric characters.
SELECT SENSOR Choose from the displayed sensor type (pH or ORP).
TEMP UNITS Choose from the displayed options (°C or °F).
LOG SETUP
Choose SENSOR INTERVAL to set the sensor log interval or select TEMP INTERVAL to set the
temperature log interval.
AC FREQUENCY
Choose 50 or 60 Hz depending on the power line frequency for optimal noise rejection. Default is
60 Hz.
FILTER Select 0–60 second signal averaging time.
TEMP ELEMENT Select type of temperature element from the displayed choices.
CAL DAYS Number of days since the last calibration. Default notification at 60 days.
SENSOR DAYS Number of days the sensor has been in operation. Default notification at 365 days.
IMPED LIMITS Set min/max electrode sensor impedance limits.
DEFAULT SETUP Resets all user-editable options to their factory-defaults.
DIAG/TEST
PROBE INFO
Display the sensor type, entered name of the sensor (Default: Digital Gateway serial number and
name), the sensor serial number, the software version number, and the sensor driver version
number.
CAL DATA Displays the slope and the date of the last calibration.
SIGNALS
SENSOR SIGNAL: displays the sensor output in mV
SENSOR ADC COUNTS: displays the sensor ADC counts
TEMP ADC COUNTS: shows raw data for temperature ADC counts. ADC counts are comparable
to A/D counts and are for sensor electronic diagnostic purposes only.
ELECTRODE STATE: Identifies the state of the electrode (good or bad) depending on whether
the impedance is within preset limits.
ACTIVE ELECT: Shows the impedance (Mohms) of the active electrode if Imped Status is set to
Enabled.
IMPED STATUS: Sensor diagnostic. Choose Enabled or Disabled.
COUNTERS
SENSOR DAYS: displays the cumulative days the sensor has been in use.
RESET SENSOR: allows the sensor counter to be reset to zero.
ELECTRODE DAYS: Cumulative days the electrode has been in use.
