The EM285 can perform various diagnostic functions. Always ensure the unit is properly connected to the vehicle's battery before proceeding.

5.1. Testing Continuity

• So atupa ilẹ iranlọwọ pọ mọ ilẹ ti o dara ti a mọ.
• Touch the probe tip to the circuit or component you wish to test for continuity.
• If the circuit is continuous, the LED indicator will illuminate.

5.2. Testing Polarity of a Voltage

• Touch the probe tip to the point where you want to test the voltagati polarity.
• The LED indicator will show red for positive voltage ati alawọ ewe fun vol oditage.

5.3. Checking Lamps and Electric Motors

• Connect the tester to the vehicle battery.
• Touch the probe tip to the positive terminal of the lamp tabi motor.
• Use the power switch to apply positive voltage (rock forward) or negative voltage (rock backward) to the component. Observe if the lamp illuminates or the motor operates.

5.4. Wiwa Awọn iyipo Kukuru

• Connect the tester to the vehicle battery.
• Trace the circuit suspected of having a short.
• When the probe tip contacts a shorted point, the LED indicator will change, or the overload protection may activate.

5.5. Testing for Bad Ground Contacts

• Connect the tester to the vehicle battery.
• Touch the probe tip to the suspected ground point.
• If the ground is good, the LED indicator will show a clear negative reading. A weak or absent reading may indicate a poor ground connection.
