A unique solution that includes six different tools, specifically developed for the automotive industry.

The UNIProbe is the evolution of the acquisition and measurement tools that assists the day-to-day experience of repair technicians and TEXA engineers.

The UNIProbe is a lightweight and handy tool with a vast range of possible applications.

Technicians often waste time changing from one tool to another when having to perform different tests on the same vehicle.

With the TEXA UNIProbe, this is no longer the case, as intuitive and standardised processing software makes it possible to instantly switch from one test to the next, without interruption.

The UNIProbe includes four different tools:

• OSCILLOSCOPE with four independent analogue channels;

• BATTERY PROBE for testing the battery, as well as analysing and checking the entire starting and charging system.

• TNET for electrical testing and analysis of automotive communication networks (CAN, VAN, LIN);

• MULTIMETER for voltage, resistance and current measurements;

Moreover, the UNIProbe can also be used as a SIGNAL GENERATOR to simulate the pulses generated by the sensors and reproduce the commands generated by the control units.

• PRESSURE TESTING: tests fuel and turbo pressure on all vehicles.

The increasing complexity of electronic devices and systems on modern vehicles naturally creates a whole new series of problems. These are quite complex, not only as regards to the repair procedures, but above all in terms of analysis and identification.

Indeed, an electrical error or malfunction may at times not always be recognised by the auto-diagnosis system on the vehicle’s electronic control unit.

In this case, the only safe way to determine the fault is to use an oscilloscope. This is in fact the most effective method for checking and displaying the electrical signals, which is why TEXA has developed this type of tool specifically for the automotive sector.

Unlike other equipment available on the market, adapted from industrial applications for use in the workshop, the UNIProbe is designed as a specific diagnostic tool for working on all types of vehicles.

This can be seen in the features of the device that, as well as the classic BNC connectors, also has a special 28-pin connector.

The purpose of this is to provide a series of additional wiring and adapters specifically for automotive applications, which are essential when performing detailed analysis on vehicle electrical systems.

The processing software has also been specifically developed for this sector, simplifying all the functions and options that made traditional oscilloscopes less practicable. The UNIProbe is extremely easy to use, yet at the same time powerful and precise as regards to the measurements acquired.

It is equipped with highly technical characteristics and guarantees, for example, a retrieval of 20MS/s with two active channels or 10MS/s with four active channels and a maximum tension of +/-50 inlet volts.

These are currently top within the current market.


Vehicle electrical problems can be divided into two main categories, based on the voltages for the correct operation of the system.

There is in fact the low voltage lines, which for instance supply the sensors and actuators, and operates up to the vehicles battery voltage,

The other line, the high voltage line, connects all the devices that operate on voltages in the hundereds or thousands of volt range.

The UNIProbe can measure and analyse both categories of signals, and does so much more simply and efficiently than any industrial oscilloscope. The analysis of the high voltage line, for example, is used to test the ignition system for petrol engines, monitoring the electrical impulses sent to the coils or the spark plugs.

Furthermore, the technological innovations implemented on the latest generation of vehicles require a power supply at a voltage much higher than 12 volts.

This is also the case of hybrid cars that have been available on the market, and are fitted with 200 volt power supply modules.

The measurements made using an oscilloscope, even the most precise and sophisticated models, are nonetheless represented on a graph that the technician must be able to analyse.

The Uniprobe has not just been developed as a measurement device but mainly as a data interpreting tool for specific software.

A help with the testing and interpretation of the signal

The oscilloscope tests performed using the UNIProbe guarantee excellent measurement of the values and precise identification of the readings; what the repair technician most needs, however, is an effective system to help correctly interpret the graphs produced by the tool.

Some faults are clearly visible, and the extent of the problem can be evaluated by simply displaying the data. In other cases, however, the deviations are minimal and are very hard to identify and interpret.

Before being able to decide whether or not the signal being analysed is correct, reference data is required, values that clearly indicate the critical points to be evaluated.

Consequently, TEXA has developed an effective technical support system that guides the technician through all the electrical tests.

The function in question is a software feature called S.I.V. (Signal Information View).

This innovative tool is found in the IDC4 Plus software for Axone 3 Mobile, Multi pegaso and PC. In IDC4 Pocket for the Axone Palmtop, Axone Pad and Axone Direct.

Thanks to this system, Uniprobe does not simply view the signal; whilst acquiring the values and data, it elaborates all the info, analyses it and provides an estimate in real time.

It can process signals from the various sensors and actuators being measured and compare the data acquired against the values stored in the internal database, thus immediately highlighting any differences in the signal.

This function is a simple and fast method of carrying out the task at hand as it provides an electrical diagram of the system to be analyzed as well as a list of its components.

By selecting the device to be tested, the ready configured Oscilloscope will be automatically activated in order to carry out the tests required.


Working on high-tech devices such as those installed in modern vehicles, requires skills that non-specialised technicians often do not fully possess.

The UNIProbe is based on the concept that any operator must be able to complete a measurement and interpret the results, without necessarily having to turn to a specialised technician to perform the repairs.

The simple and user-friendly display interface, plus the software with S.I.V. function that helps the operator identify the faults, are TEXA’s response to the most common problems that arise in the workshop.

As already highlighted, the UNIProbe can analyse the measurements acquired and instantly compare them against the standard data for each specific system or device.

For low voltage tests, such as acquiring the signal from a throttle potentiometer, the software displays the typical bell curve of the acceleration and, if it detects any micro-interruptions, freezes the image and highlights the fault on a graph.

Similarly, for high voltage tests, both systems with spark plug cables and those with integrated coils can be analysed; in this case too, the UNIProbe directly highlights which spark plug or coil is the cause of the ignition failure.

Two different methods of acquiring the signal, yet managed by the same software and displayed in a standardised format.

UNIProbe has been specifically developed to a high standard to be used within a workshop.

It has an internal battery which allows the tool to be used up to six hours without an electrical supply via wires.

Under a standard configuration, it is directly charged by the vehicle it is testing.

1. The example displays the automatic analysis carried out on a throttle potentiometer via the electrical signal. The break point which occurs at a precise opening angle may be noted.

2. More automatic analysis examples on a square waved signal. In such a case; a signal break caused by a faulty electrical connection with the wiring may be noted.

3. Even during high tension testing, the program proposes different function methods to view and carry out automatic checks. The example displays a graph which shows the amount of time sparks occur whilst a 4 cylinder engine is being started.


The car won’t start? The problem could be a flat battery. One of the most important checks in this case undoubtedly involves measuring the energy levels throughout the system consisting of the starter motor, alternator and battery.

The Battery Probe and BPP kit can be used to simply run a complete check on all the components in the system, giving a certain diagnosis of the problem and allowing the right repair to be made.

The BPP kit features 4 analogue inputs and two connectors for attaching to the current tester probes.

A semi-automatic diagnostics system analyses the starting system as a whole (i.e. all the components and the wiring) to identify the cause of the fault. Based on the measurements acquired, the software generates a possible diagnosis, indicating the most plausible cause of the malfunction.

This is produced in the form of a report that can be printed and given to the customer, describing the details of the measurements made and the checks performed.

The repairs are thus backed by supporting test documents that can be used to explain the reason for the replacement of the alternator or the battery.

In a network communication BUS (for example CAN, VAN, LIN), electrical and electronics faults may not depend on the systems and the components, but rather on physical damage to the electronic network.

This may occur, for example, following physical damage or deterioration of the wiring.

In other cases it may depend on work performed during repairs or service that interrupted or detached a cable.

Finally, it may be due to auxiliary devices and control units that have not been installed properly. In all these cases, the TNET module integrated in the UNIProbe can be used to directly analyse the electrical wiring in different types of networks.

This doesn’t require sophisticated tools or advanced technical knowledge.

TNET simplifies troubleshooting by clearly and effectively displaying the results of the measurements.

Two test probes are used to take the measurements directly from the network wiring, with the results displayed highlighting whether or not there are electrical faults.

If the test fails (that is, errors are identified), the tool provides details on the fault, specifying the possible causes.

It can also print a report on the specific problem, for example interruptions, short-circuits or abnormal load conditions.


Alongside the BNC connectors, on the front of the UNIProbe, are two jacks, the inputs for the multimeter module.
As well as traditional voltage, resistance and current measurements, this can also carry out functions such as diode tests and continuity tests, plus a special electrical measurement function known as the “data logger”.
- VOLTAGE measurements: the maximum measurable voltage is ± 400 VDC, over three ranges (0V-6V; 6V-60V; 60V-400V AC/DC).
- RESISTANCE measurements: three ranges of values are available, with automatic or manual scale selection (0?-1000?; 1k?-100k?; 100k?-10M?).
- CURRENT measurements: performed using the TEXA current clamps (the BICOR series probes can also be used).
- DIODE tests: to determine whether or not a diode is working correctly, as well as the diode bias (if forwards, a buzzer sounds).
- CONTINUITY test: to check whether there is a short-circuit between two terminals (if the resistance is less than 50 Ohms a buzzer sounds).
- DATA LOGGER function: the tool monitors slow signals as variable voltages or resistances and then records their variations over time.
