Positive&Negative Identification: In the measurement, the red and green light-emitting diodes are used to distinguish the positive and negative polarity of the measurement power supplys, which is intuitive and fast.
Bulbs Measurement: Using a 5W car bulbs as a load, it can quickly determine the power supplys failure of the line. Compared with a diode tester, it can find some invisible failures of poor contact and virtual voltage.
Load Voltage Measurement with Bulbs: By measuring the brightness and dark of the electric pen bulbs, the line voltage fault can only be roughly judged. With the voltmeter function of the electric pen, more accurate measurement can be achieved, thereb
Pulse signals such as Hall sensor, ignition pulse, fuel injectors pulse, etc. can be measured conveniently and quickly through the diode of the electrometer.
For the load plug, you can use the probe attached to the clip, combined with the probe of the electric test pen, to directly measure, which is convenient for fault diagnosis.
