Put SW2 in the 12V position, put SW1 in the <4Ah position. Connect the
supplied 8.2Ω resistor in series with the multi-meter. Switch the multi-meter
to the '10A DC' -position. It should read 0.3A +/- 0.03A.
If any of the measurements show a considerable difference with the refer-
ence values, please recheck the entire assembly, and pay special attention
to resistor values.
Use :
Perform the necessary settings before you hook-up the battery to the unit :
Select the appropriate charge current and voltage according to the capacity
of the battery.
Batteries < 4Ah : 0.3A charge current
Batteries > 4Ah : 1A charge current
You can easily estimate the charging time with the following formula :
Approx. charging time (hours) = (battery capacity (Ah) / charging current (A))
x 1.2
Pay attention to the polarity when you hook-up a battery to the charger.
Switch on the unit, to start the charging cycle. Batteries should be charged
in a well ventilated area, because of the possible emission of gases. Do not
cover the unit during charging, as it might result in overheating or even fire.
