The P300 is an electrical tester for the diagnosis of vehicle batteries and electrical systems from 6 to 30 volts, easy to operate and widely useful , after simply connecting the tool to the vehicle battery:
*Quickly diagnose positive and negative circuits .
*Accurately analyze battery health status.
*Tests continuity using the built-in auxiliary ground lead.
*Presses the power switch and conducts positive or negative battery current to the probe tip to test the function of electrical components without the use of a jumper wire.
*To immediately tests for poor ground contact without voltage drop testing . Short circuit protection is also provided. The internal circuit breaker trips if overloaded.
*Trace and locate short circuits without wasting fuses . The tool's long cable allows you to test along the entire length of the vehicle, eliminating the need to constantly search for a suitable vehicle ground.
Inteligent Testing and DC & AC Measurement
Inteligent testing can quickly detect voltage, resistance and diodes in vehicle electrical system wiring .
Connect the red alligator clip to the positive battery terminal and the black alligator clip to the negative battery
terminal.
After the equipment is switched on,there is no need to select the detection mode, it can carry out intelligent detection
on the vehicle , and automatically identify the voltage of the wire ,the resistance value of the parts, diode and so on.
There are three multimeter functions to choose from: DC measurement,resistance measurement, and diode detection.
When DC Voltage mode is selected , the BAT displays the current device supply voltage and the probe tip makes
contact with the positive and negative circuits.
(1) Measure the positive circuit,the red LED will illuminate and the LCD will display the current circuit voltage . If the
buzzer is on, the unit Will emit a high tone.
(2) To measure the negative circuit , the green LED will illuminate , the LCD will display 0.0V , and the unit Will emit
a low-pitched tone.
(3)If you touch the probe tip to the open circuit, both LED will not light up.
Battery Tester
Starting test can detect the current starting performance of the battery , which helps to judge the service life of the battery.
Select [Battery] , press [OK] to confirm , select [Startup test] and operate according to the product interface prompts to view the test results.
Charging Test: Select [Battery], press [OK] to confirm, select [Charging test] to continue and view the test result:
Load Test: The load test can record the voltage fluctuation of the car turning the load on and off in real time , and can accurately determine the health status of the battery.
Select [Battery Test] , press [OK] to confirm , select [Load Test] , enter the function , follow the on-screen prompts to operate and view the test results
Jumper lead function: The black clamp and auxiliary earth wire are connected directly through the device, disconnecting the red clamp from
the vehicle battery, the device can be used as a long jumper lead , (note that when the device is used as a jumper
function , care should be taken to avoid short-circuiting and overloading, and that the jumper lead function is not
protected by the device's circuit breakers)
Activate the interior parts & Grounding activation element
- Activate the interior parts: When the tool is in DC voltage mode , touch the tip of the probe to the positive terminal of the component, the green LED should illuminate indicating connectivity to ground, while observing the green LED, press and release the power switch quickly forward , if the green LED goes out and the red LED comes on the activation can continue, if the green LED goes out or the circuit breaker is tripped at that instant , the tool has been If the green LED goes out at that moment or the circuit breaker trips, the tool is overloaded.
WARNING : When using this feature , if you are touching
a protected circuit , grounding it may cause the vehicle fuse
to blow or tripWARNING : Applying random voltages to certain circuits may damage the vehicle's electronics . Therefore , it is strongly recommended that the vehicle manufacturer's wiring diagrams and diagnostic procedures be used during testing. NOTE : If the circuit breaker trips , wait for it to cool (5 seconds) and then press the reset button to reset it. When energising a component , if the switch is pressed first and then the tipis touched to the component then the life of the power switch can be extended. Arcing will occur at the tip, not at the contacts of the switch.
- Grounding activation element: When the tool is in DC voltage mode , touch the tip of the probe to the negative terminal of the component, the red
LED will light up, while observing the red LED, quickly press back and release the power switch, if the red LED goes out and the green LED lights up , activation can continue. If the green LED is off or the circuit breaker trips, the tool is overloaded. This can happen for the following reasons:
*The contact you are probing is direct positive voltage.
*The component you are testing is a shorted component.
*The component is a very high current component (e.g. starter motor).
If the circuit breaker trips , wait 5 seconds for it to cool down and press
WARNING : When using this feature , if you are touching a protected circuit , grounding it may cause the vehicle fuse to blow or trip
Circuit breaker has a short circuit protection function, and its internal circuit breaker will trip if overloaded.
When the short circuit breaker trips, the screen will appear as follows. At this time, the device is already in a protective state, even if the power button is pressed, the device will not direct the current to the tip of the probe, which can effectively prevent unnecessary damage caused by accidental operation . This effectively prevents unnecessary damage caused by accidental operation.
Note: when the unit trips you need to wait for 5 seconds to cool down and then press the s ide reset button for normal use.
