Calibrate
The Calibrate menu allows adjustment of the controller’s battery voltmeter. If a controller’s readings do
not match those of another device or a hand-held meter, calibration may improve consistency.
Figure 45 Calibrate
NOTES:
Calibration does not change the charge controller’s actual voltage, only the reading.
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
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, it is an issue with the system, not the FM100. Calibration cannot correct for it.
This function does not affect system display voltages from other sources such as the
FLEXnet DC Battery Monitor or an inverter.
Calibration does not affect Battery Sense terminal voltages (see page 20), as calibration
is unnecessary when Battery Sense is used. The Calibrate screen will have no effect.
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 64. This procedure is recommended
any time the controller is relocated or the system is substantially revised.
This procedure is a requirement for resetting the nominal battery voltage of the system (see page 27).

s
menu:
1. Access the main menu as shown on page 41.
2. Select the Settings screen. (This option may be
highlighted by default.)
3. Select Charge Controller
in the device Settings menu.
4. Select the Reset to Factory Defaults screen.
5. Use the soft keys to select No or Yes.
If <

> is selected, the screen returns to the
Charge Controller
menu. No changes will be made
to any settings.
If <
Yes

immediately change to the original factory values.
The screen will display the message
Charge
Controller Restored to Factory Defaults.
A <

> soft key will appear. Pressing this
key will return the screen to
Charge Controller
.
6. After resetting the charge controller to factory default
parameters, turn all power to the controller (PV and
battery) off and then on again.
Press <Continue> to return to the Charge
Controller menu (if the MATE3s is still active).
