Car Circuit Tester Pen Auto Fuse Test Probe Light Tool for 6V 12V 24V AC Voltage

Description

The multifunctional vehicle tester makes up for various deficiencies of the existing vehicle maintenance tester. It integrates the functions of voltage measurement, bulb load measurement, bulb load voltage measurement, electrical load test, power supply polarity display, etc. It has a novel design, exquisite workmanship, easy to use, practical and durable; It is a 12V/5W or 24V/5W bulb that is often used in cars.
Features:
1. Voltage measurement function.
2. Ball load measurement.
3. Voltage measurement with bulb load.
4. For the load plug, you can use the probe directly connected to the clip, combined with the probe of the test pen, to directly perform the load simulation measurement, which is convenient for fault diagnosis.
5. Voltage polarity display function.
6. Three detection modes switch.
7. Multi-band frequency detection can be realized.
Functions:
Check the fuse.
Check battery performance.
Detection of positive and negative power.
Detect LAN local area network circuit.
Test Hall sensor performance.
Detection of short circuit faults.
Distinguish between real electricity,virtual electricity, series electricity and poor grounding.
Fault code reading function.
Torch lighting function.
Detect vehicle speed sensor.
Detection of ABS circuit.
Detect the idling circuit, ignition circuit.
Circuits such as fuel injection circuit.
REAL -TIME VOLTAGE DISPLAY
The voltage tester has a special LCD screen, it will displayThe voltage isclear at a glance. With lamp beads, it is more convenient to use at night.
POSITIVE AND NEGATIVE IDENTIFICATION
LED lights prompt, quickly identify the positive and negative poles
3 MODES SWITCH
There are 3 modes in total. The mode switch is operated by the physical buttons of the electric pen body. Press and release the button to cycle through the three working modes.
MODE 1
LED digital display and bulb work at the same time.
MOOE 2
LED dgital display works, the bulb does not work.
MODE 3
LED digital display does not work,bulb works normally.
FREQUENCY PREDICTION
When the electric pen is connected to an AC signal (5~30V), the
frequency range can be estimated through the display of the
digital tube. Can be used to measure fuel injector signals,
spark plugs, crankshaft sensor signals, etc.
