5.4pH Sensor Setup Menu (continued)

CONFIGURE (continued)

	REJECT FREQ	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.
	SELECT BUFFER	Select the buffer type (standard 4, 7, 10 or DIN 19267) from the displayed choices.
		Allows the user to specify that ammonia, morpholine, or other user-defined electrolyte is being
	PURE H20 COMP	used in the application, allowing a temperature-dependent linear slope factor to be applied to the
		measured pH.
	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.
	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 pH 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: Displays 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: Displays 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.
