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 hand-held meter, the calibration
feature may improve consistency.
Figure 76 Calibrate
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
charge controller. Calibration cannot correct for it.
Reset Charge Controller to Factory Defaults
This menu allows the user to erase all settings from the selected charge controller and start over with
the values programmed at the factory. These values are listed on page 94.
