SYSTEM SETUP CURRENT INPUTS mA INPUT INT/EXT

			Default value: DIRECT
	LOGIC		Sets the relation between input state and output level.
			The menu item is displayed if SET FUNCTION is set to DIGITAL.
		DIRECT	If the input contact is closed the output level is LOW respectively if the input contact is open the
			output level is HIGH.
		REVERSE	If the input contact is closed the output level is HIGH respectively if the input contact is open the
			output level is LOW.
	SCALE 0 mA/4 mA		Default value: 0–20 mA
			Sets the input current range either to 0–20 mA or 4–20 mA.
	SET HIGH VALUE		Default value: 20
			Sets the value of the output value when the input current is 20 mA.
			Default value: 0
	SET LOW VALUE		Sets the value of the output value when the input current is 0 mA (0–20 mA scale) or 4 mA
			(4–20 mA scale).
			Default value: OFF
	ON ERROR MODE		An error is reported when input current is out of range (this can be 0–20 mA or 4–20 mA).
			When set to “OFF” no error will be reported even if the input current is out of range.
		0 mA	Substitute value is 0 mA in case of error.
		4 mA	Substitute value is 4 mA in case of error.
		20 mA	Substitute value is 20 mA in case of error.
		OFF	No substitute value is used to replace the measured value in case of an error.
	CONCENTRATION		Displays the calculated concentration depending on the input current and the scaling which is set
			in the SET LOW VALUE and SET HIGH VALUE menu.
			Default value: 10 minutes
	LOG INTERVAL		Sets the interval for logging the displayed value into the data logger.
			Options: OFF, 5min, 10min, 15min, 20min, 30min
VERSION			Displays the software version number
LOCATION			Displays the current location
