ABOUT BT280 Overview The BT280 is the newest generation intelligent electrical system circuit tester with 2.4 inch large size LCD screen display. It is dedicated to test all 9V~30V vehicle electrical systems. BT280 is convenient, fast and intelligent! Specifications (320*240 DPI)
PRODUCT STRUCTURE Structure diagram ● A - Probe Tip – Contact the circuit or component for testing. ● B - Front LED Light – Used for lighting in dark working areas or when working at night. ● C - LCD Screen – Display test results. ●...
PRODUCT USE Power supply The Probe is powered by the vehicle battery. Connect the RED connection clip to the positive pole of the battery, and the BLACK clip to the negative pole of the battery. The machine will automatically start to enter the working interface, The front LED light will illuminate the test area, which is convenient for operation in the dark area.
NOTE: Do not use the BT280 probe to test the voltage of the house- hold AC Power (such as 110V, 220V plug), it may cause serious injury and property damage for improperly operation.
WORKING MODE This probe adopts a 2.4-inch large color screen and 9-grid interface design, with clear display, simple operation and quick in use. You can select working mode through the navigation buttons and press OK to enter. Smart test The main test functions of this mode: voltage test, resistance test, Positive / negative test.
Resistance Test Result ● How to use: When the probe clip (auxiliary ground lead) is connected to an electrical circuit of resistance and the probe tip is connected to the other end of the resistance, the probe will automatically enter into the resistance display mode and display the resistance values.
right are: DC voltage (VDC), resistance (OHM), diode/continui- ty test (DIO), current (AMP), frequency (HZ). How to use Press the “right” button to select the test mode. Press “Left” Button to exit. ● DC voltage (VDC): Connect the probe clip (auxiliary ground lead) to the negative pole, and connect the probe Tip to the measured voltage.
keys to adjust the voltage value). ● “Time” time parameter. ● “HZ” Display test frequency. *Press and hold left key to exit this working mode. Relay test Instructions ● The “VCC” at the top of this interface displays the power supply voltage value.

Display Value ● VDC: Detected Voltage ● AMP: Detected Current ● VCC: Power Supply Voltage Activation Type ● “MOMENT” Mode: Press “Right” button to select the activation mode to MOMENT mode. Press and hold the “UP” / “Down” button to perform the power supply, Press Release Release “UP”...
“SET” Circuit Breaker: ● Press “Right” button to select the activation mode to SET mode. Press “UP” / “Down” button to adjust the overload current values from 1A~18A. If the current flowing through the probe is greater than the set value, it will cut off the power and stop activation.
Injector test The probe outputs different pulse signals to the injector, and check the injector spraying status. This function can help diagnose injector conditions. It can work with any fuel pressure tester. Signal Output Mode ● MODE 1: Press “OK” button to activate probe outputs 1 pulse. Pulse width is 250ms.
Positive / How to use Negative test ● Connect the probe negative clip to the vehicle ground wire, use the probe tip to find the positive / negative wire of the electric circuit system. The following interface is displayed default state: Positive Interface ●...
Setting ● From setting interface, you can set, sound, language, update, screen, use “UP” and “DOWN” button to select, press “OK” button to change parameters. Press “LEFT” button to save and exit. Online Update ● After in setting interface, select update menu to enter into update mode.
TEST APPLICATIONS Continuity When the probe is in the “Multimeter mode” select resistance test testing function, Use the probe tip with chassis ground of the vehicle or auxiliary ground lead, continuity can be tested on wires and components attached or disconnected from the vehicles electrical system.
Use an OBD2 Scanner to read out the FAULT CODE (DTC) from Signal circuit the vehicle and found the problem is with some kind of sensor testing circuit, there is a fast way to testing the sensors conditions with (Oscilloscope this probe.

● The LCD screen will display the value of VDC, AMP, and VCC. If the Probe restart for the circuit breaker tripped or the displayed message OVERLOADED on LCD screen, you can adjust the overload current value and repeat the above operation to further activation.
● The component is a very high current component (such as STARTER MOTOR). NOTE: Activating components The activation mode is only designed for supply powers or in vehicle ground, and cannot be used for any sensitive electronics equipment (such as ECU, sensor module), otherwise there is a risk of burning out components.
If the probe circuit breaker tripped, it means the probe is overload- ed. This could happened by the following reasons: ● You have connected the probe tip to the direct ground or nega- tive voltage. ● The component you are testing is short circuited. ●...
(To avoid burning out the component, please refer to the specifica- tion and parameter of component and then set the OVERLOAD CURRENT VALUE ) If the probe circuit breaker tripped, it means the probe is overload- ed. This could happened by the following reasons: ●...
● Press “OK” button to trigger power supply. The RED led light will ON and LCD screen will display values of VDC, AMP and VCC, if the VDC value is almost the same as VCC and AMP value is minimum approach to 0A. it means this is not true ground.
Trailer lights ● When the probe is in multimeter or SMART test, connect the and connec- probe auxiliary ground lead to the trailer light, and insert the tion test probe tip into the OBD socket to display the current voltage. With this method you can check the function and direction of the connector and trailer lights.
