3. Calibrated DC Multimeter with 30V and 10A ranges
4. Time reference (watch, clock, etc. with elapsed seconds)
5. Power Cord
6. Appropriate Battery connection cord for the selected battery
Approximate Duration of Test: Ten minutes, plus setup time.
Field Test Procedure:
1. Power on Charger with battery disconnected
2. Verify screen shows 00.0V and 00.0A
3. Connect 12V or 24V battery (as available) and configure charger:
a. Select 12V or 24V (as appropriate),
b. Select 6A,
c. Select End At .5A; press Go!
4. Set DMM to voltage mode, connect DMM in parallel with battery.
5. Verify DMM matches voltage on screen (+/- .5V)
6. Press Pause.
7. Verify DMM matches voltage on screen (+/- .2V)
8. Set DMM to current mode, connect DMM in series with battery (10A mode)
9. Resume charge (press Go!)
10. Verify DMM matches current on screen (+/- .15A)
11. Cancel charge: Select Pause, then select End.

a. Verify selection on screen is still 12V or 24V (as appropriate),
b. Select 1A, End At 65h (or any time limit – charge will be interrupted) press Go!
13. Verify DMM matches current on screen (+/- .15A)
14. Observe countdown timer over period of 30 seconds as measured by time reference
15. Verify that 30 seconds elapsed on time reference and unit simultaneously (+/- 2 seconds)
16. Cancel charge: Select Pause, then select End.
17. Remove DMM from circuit and reconnect battery to charger
18. Set DMM to voltage mode, connect DMM in parallel with battery.
19. Verify DMM matches voltage on screen (+/- .2V)
20. Disconnect battery and reconnect battery in reverse polarity.
21. Verify screen indicates reverse polarity
