Parameter list and description

P=Parameter,	D=Diagnostic Display Parameter
Parameter	Description
No.
P100	Sensor Gap in mm.
	This is a user entered parameter (optional).
	This value is ignored when an alternative span
	calibration is caried out (i.e. method two or three).
P101	Sludge type
	The user can select from a list of sludge type to set
	up the span for the calibration procedure (optional).
	Each sludge type is associated with an attenuation
	factor for each frequency. This value is ignored when
	an alternative span calibration is caried out
	(i.e. method two or three).
P102	dB Factor @ 1MHz
	A user alterable parameter. This is the attenuation
	number in dB/% at 1MHz. This is used for the span
	calibration (method three).
P103	dB Factor @ 3.3MHz
	A user alterable parameter. This is the attenuation
	number in dB/% at 3.3MHz.This is used for the span
	calibration (method three).
P120	Zero Ref @ 1MHz
	This is the value in dBs (@ 1MHz) that is stored in
	the control unit when a zero calibration is carried out.
	This value is over written each time a zero calibration
	is carried out.
P121	Zero Ref @ 3.3MHz
	This is the value in dBs (@ 3.3MHz) that is stored in
	the control unit when a zero calibration is carried out.
	This value is over written each time a zero calibration
	is carried out.
P122	Date of Zero Ref
	This is automatically stored by the control unit when
	the zero calibration is done. The actual date can be
	set-up in the ENGINEER menu (P730)
P123	Initial Zero Ref @ 1MHz dB’s
	This is the value in dBs (@ 1MHz) that is stored in
	the control unit when the initial zero calibration is
	carried out.This value is compared with subsequent
	zero calibrations.0 must be entered to reset or clear initial
	zero value
P124	Initial Zero Ref @ 3.3MHz dB’s
	This is the value in dBs (@ 3.3MHz) that is stored in
	the control unit when the initial zero calibration is

carried out.This value is compared with subsequent

zero calibrations.0 must be entered to reset or clear initial
