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
		Display the sensor type, entered name of the sensor (Default: Digital Gateway serial number and
	PROBE INFO	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.
		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.
	SIGNALS	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.
		SENSOR DAYS: displays the cumulative days the sensor has been in use.
	COUNTERS	RESET SENSOR: allows the sensor counter to be reset to zero.
		ELECTRODE DAYS: Cumulative days the electrode has been in use.
