-3- Put SW2 in the 12V position, put SW1 in the >4Ah position. Connect
the supplied 33 Ω/5Ω resistor to the output terminals. Measure the
voltage across the resistor.
It should read 14.7V +/- 0.1V
-4- Put SW2 in the 6V position, put SW1 in the >4Ah position. Connect
the supplied 33 Ω/5Ω resistor to the output terminals. Measure the
voltage across the resistor. It should read 7.3V +/- 0.1V
