DC Output Calibration | Marathon Computer AACC 2000 guide

Marathon Monitors Inc.

Select ‘YES’ with or Wait for calibration to complete.

YES	Start calibration

buSy	Busy calibrating
donE	PV input calibration completed
FAIL	Calibration failed

Note. When a DC input module is installed for the first time, or there is a requirement to change one, then the microprocessor in the controller needs to read the factory calibration data stored in the module. Select ‘FACt’ as the calibration value. Step to ‘GO’ and start calibration.

DC Output Calibration

The following parameters apply to DC output modules ie for rcAL = 1A.Hi to 3A.Lo

cAL.H	Output Calibration High	0	0 = Factory set calibration.
			Trim value until output = 9V, or
			18mA
cAL.L	Output Calibration Low	0	0 = Factory set calibration.
			Trim value until output = 1V, or
			2mA

User calibration

UCAL	User calibration enable	Yes/no
pt1.L	Low calibration point for Input 1	The factory calibration point at which the
		low point offset was performed.
pt1.H	High calibration point for Input 1	The factory calibration point at which the
		high point offset was performed.
OF1.L	Offset Low for Input 1	Calculated offset, in display units.
OF1.H	Offset High for Input 1	Calculated offset, in display units.
pt2.L	Low calibration point for Input 2	The factory calibration point at which the
		low point offset was performed.
pt2.H	High calibration point for Input 2	The factory calibration point at which the
		high point offset was performed.
OF2.L	Offset Low for Input 2	Calculated offset, in display units.
OF2.H	Offset High for Input 2	Calculated offset, in display units.

Name	Description	Values	Meaning

PASS	Password configuration
ACC.P	FuLL or Edit level password
cnF.P	Configuration level password

Exit	Exit configuration	no/YES
