6) (Optional, for use with power resistor) Wire, #22AWG (0.65mm), 6 ft (2 meters)

7) (Optional, for use with power resistor) Wire, #18 AWG (1mm), 6 ft (2 meters)

Procedure:

1) (Optional) Into each tip plug connect 3 feet of #18AWG and #22AWG wire. The

#22 will go to a voltmeter and the #18 will sometimes be connected to the power

resistor.

2) Connect the Activator 282 to a Lead Acid battery and set the front panel switch to

“Lead Acid”.

3) Connect a voltmeter to the red and black tip jacks on the Activator 282, either

directly or through the added #22 wires.

4) Turn on the Activator 282 to charge the battery. Leave the Activator 282

charging the battery for at least three charge cycles, so that the Activator 282

“topping charge” is only two minutes.

5) Observe the voltmeter as the battery approaches 28 Volts with the Activator 282

yellow CHARGING LED lit. When the green READY LED comes on, note the

highest voltmeter voltage. That must be 28.2V within ± 0.3 Volts. If not, the

Activator 282 must be returned to the factory for repair and calibration.

NOTE – the topping charge will slowly raise the battery voltage above the

internal charge voltage threshold. Using a two minute topping charge

minimizes this error. Using a good battery minimizes this error.

6) (Optional, for use with power resistor) With the voltmeter still connected and the

Activator 282 showing the green READY light, apply the power resistor across

the two tip jacks through the #18 wire harness constructed above. This will

discharge the battery, since the Activator 282 has cut off charging when the

READY light is illuminated.

7) Observe the voltmeter as the battery voltage approaches 25.2 Volts with the

Activator 282 green READY light illuminated. When the yellow CHARGING light

comes on, note the lowest voltmeter reading. That must be 25.2W within ± 0.3

Volts. If not, return the Activator 282 to the factory for repair and calibration.
