How to use BT-400
| connecting method |
battery test |
activate engine |
generator |
- To dismantle and grounded to green clip.
- Red clipconnect to positive polarity
- Black clipconnect to negative polarity
|
- Battery voltage value
- To set battery capacity
- Discharge test 5 seconds
- Test value readings
|
To look at 600A minus value at Amper gauge when activated, the current value readings |
- 2000RPM after activated
- Turn on all equipments in the vehicle
- Voltage gauge must be at blue area
- Press white button 60A to judge charging and discharging status
