Calibrate - Alpha Group OutBack Power MATE3 Owner's Manual

Calibrate

The Calibrate menu allows adjustment of the inverter's internal voltmeters. If a particular inverter's
readings do not match those of another inverter or a handheld meter, the calibration feature may be used
to improve consistency.
To access the Calibrate menu:
1. Access the Inverter menu as shown in Figure 71 on page 75.
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 change the Input Voltage set point.
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. Use the control wheel to change the Output Voltage set point.
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.
5. Use the control wheel to change the Battery Voltage set point.
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.
6. After setting the parameters for each set point, press the TOP navigation key to return to the
Main Menu screen.
Set Points:
 Input Voltage: Calibrates the AC voltage
measurement made at the inverter's AC input
(from an incoming AC source).
 Output Voltage: Calibrates the AC voltage measurement made at the inverter's AC output (from the
inverter's own power, or from an incoming AC source).
 Battery Voltage: Calibrates the DC voltage measurement made at the inverter's DC terminals.
Figure 88 shows the current readings being taken by the inverter in Vac and Vdc. However, the field to the
right of each value is the calibration setting. The settable range will vary with inverter model. See the
inverter Operator's Manual for specific ranges.
Note : Calibration does not change the actual output of the inverter, only the reading of that output.
Also, measurements in places other than the inverter's terminals may differ regardless of calibration. For
example, it is possible to get a different reading at the inverter'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.
