Calibrate - Alpha Group OutBack Power MATE3 Owner's Manual

Calibrate

The Calibrate menu allows adjustment of the charge controller's battery voltmeter. If a particular
controller's readings do not match those of another device, or a handheld meter, the calibration feature
may improve consistency.
To access the Calibrate menu:
1. Access the Charge Controller menu as shown in Figure 90 on page 94.
2. Use the control wheel to highlight the Calibrate menu.
Press the button in the center of the control wheel to accept the selection.
3. Use the control wheel to increase or decrease the set points to the correct voltage. Press the button in
the center of the control wheel to accept the selection. This should automatically move the
highlighting to the next set point.
4. After setting the parameters for each set point, press the TOP navigation key to return to the
Main Menu screen.
Set Points:
 Battery Voltage: Calibrates the DC voltage measurement made at the charge controller's battery
terminals.
 Figure 104 shows the current reading being taken by the charge controller in Vdc. However, the field
to the right is the calibration setting.
Note : Calibration does not change the actual voltage of the charge controller, only the reading of that
voltage.
Also, measurements in places other than the charge controller's terminals may differ regardless of
calibration. For example, it is possible to get a different reading at the charge controller's DC terminals
than on the batteries. Connection problems, corrosion, and the effects of induction and resistance may all
result in voltage differences. If this occurs, note that this is an issue with the system, not the inverter.
Calibration cannot correct for it.
