Jdiag P200 Smart hook is the newest generation intelligence circuit tester with 2.4 inch large size LCD screen display, it is dedicated to test all 9v-30v electrical systems for cars, motorcycles and trucks, smart hook tester is convenient, fast and intelligent.

1.Smart test mode

Smart test mode is designed to detect resistance values or voltage values automatically.

When you test the probe tip to an electric system, it will display voltage values, if it detected voltage signal.

And when you test the resistance, it will display as ohms. So you don’t need to switch between voltage test and resistance tests.

2.Multi meter test mode

The function is completely the same as you’re using a multi meter, you can perform voltage test, resistance test, diode continuity test, current test and frequent test.

3.Oscilloscope Test

Oscilloscope Test is quite useful to diagnose sensors, actuators and communication signals.

With this simple oscilloscope test function, you can diagnose maximum minimum voltage, waveform frequency and duty cycle.

4.Relay test mode

There are two common relay types: 5 terminals and 4 terminals.

Put the relay test cable into the probe and check the connection diagram.

Clip on the cables to each terminal on the relay.

And press UP button to trigger power supply to test relay working status.

5.Activation test mode

the activation test function is designed to generate activation signals to the tested components such as car lights, motors and other on board electric equipment.

Here is activating a car light.

There are three activate modes: moment, latch and pulse, you can also set the overload current values.

6.0-5V Safety power supply mode

Safety power supply is different from the activation test.

In this mode, you can adjust output voltage under 5 volts and output current to 100 milliamps, this is a safety way to protect the sensitive sensors.

7.Fuel Inject Test Mode

There are four test modes in this function, the probe output different pulse signals to the injector and check the spraying status.

It can be worked with any fuel pressure tester, this is a good way to diagnose injector working conditions.

8.Positive / negative test mode

This function is designed to quick find the circuit polarity in electrical system, it will display voltage values, ground icon after detected related signals.

Finally, Setting

From setting interface, you can perform sound, language and firmware upgrade. There are more than 20 languages selectable in Jdiag P200 Smart Hook Circuit Tester, and you can also do online updates for free.
