The Sweep Interval mode or mini-sweep determines how
often a sweep occurs, ranging from 0-15 minutes. A
sweep is a search for the best MPP for the array. At zero
minutes, the MPPT mini-sweep function is disabled (this
is not recommended for PV arrays). No sweeping occurs if
the output current is under  ve amps because it operates
at the Park Mpp value. Sweeping does occur when the
output current is higher than  ve amps or to maintain
user current limit and to track the MPP of the array
throughout the day. A mini-sweep is an accurate but less
extensive version of the full initial sweep done at wakeup.
Press the <–MIN> soft key to decrease minisweep
interval minutes or press the <+MIN> soft key to increase
the minutes. Press the <NEXT> soft key to view the Vbatt
Calibration screen.
A quality calibrated voltmeter will provide even more
accurate MX60 battery voltage readings if an undesirable
voltage drop is present. When measuring battery
voltage, ensure a good connection is made to the Four-
Position Terminal Block. Check the battery temperature
compensation voltages if voltages are much di erent
than you expect from the charger setup Absorb and Float
voltage settings. Use the <-V> and <+V> soft keys to
match the readings from the voltmeter. When  nished,
press the <NEXT> soft key to view the next screen.
The present Vbatt meter reading is
