QST-5 Sensor Tester

The QST-5 device is intended for testing many popular sensors used in the automotive industry. The tester powers the tested sensors by itself, so it can be used both in a vehicle and outside of it. Sensors which can be tested with QST-5:

  • Crankshaft and camshaft sensors,
  • ABS sensors,
  • Rotary speed sensors,
  • Temperature sensors (thermistors)
  • Fuel/oil pressure sensors,
  • Sensors of throttle, EGR, and turbine position,
  • Accelerator pedal positions sensors,
  • MAP and turbocharging sensors,
  • Knock combustion sensors,
  • Clutch/brake pedal sensors,
  • DPF/FAP differential pressure sensors,
  • Sensors of air conditioning pressure,
  • and others.

Thanks to QST-5, testing sensors is easy and convenient. The sensor is connected with three numbered endings. The device can automatically indicate the type of the tested sensor (e.g. inductive or Hall) and establish the terminals. Then the user can perform a functional test, testing its response in different test conditions.

Device’s advantages:

  • – Quick and safe sensor tester that doesn’t require knowledge of terminals.
  • – Easy to use: perfect for beginner users,
  • – Integrated measurement of R,L,C electrical parameters.

Additionally, there is an option to download an Android application (smartphones, tablets) which allows to remotely read measurement screens and add sensors together with their parameters and an optional photo to the database.

Technical parameters:

– Resistance measurement: 0 – 5MΩ
– Inductance measurement: 1mH – 5H
– Capacitance measurement: 100p – 2u
– Diode test: 0,1 – 3V.
– Sensor supply: 5V DC
– Power supply: built-in Li-ion battery
– Operating time: min. 6 hours when fully charged

Kit contents:

QST-5 – FAQ

 

I lost my software CD. How can I get the firmware update tool?

The program for updating the device can be downloaded after prior registration and logging in to our website: https://dte.com.pl/en/my-data/.

 

Where can I find the QST-5 application for phone / tablet?

Only the Android app is available. The application can be downloaded after prior registration and logging in to our website: https://dte.com.pl/en/my-data/.

 

Can I test sensors powered by 12V ?

The QST-5 tester supplies the tested sensors with 5V. It is one of the elements of protection against possible damage to the sensor by the tester. Very often, the tester is able to correctly test sensors such as crankshaft or camshaft sensors, supplied with originally higher voltage. In most cases, these sensors operate in a much wider range and it is related to their construction. There may be sensors that actually require higher voltage to function, but account for a smaller proportion of the total. Similarly, most ABS sensors in the circuits are powered by higher voltage, but their mode of operation (current output) make them work properly when powered from QST-5.

 

Can I test a oxygen sensor or MAF?

The device works only with sensors that require power from the ECU with low current and voltage. Elements such as the oxygen sensor or the MAF flow meter have heating elements, supplied with higher current with on-board voltage. Elements of this type cannot be powered by the tester (do not connect external voltages in parallel to the tested elements due to the risk of damage).

 

Does the application contain a database with reference values?

The QST-5 application has a database of measurement results to which the user can save his results with an given annotation. This database can be used by the user to diagnose similar sensors in the future. The software does not provide information about the parameters of individual sensors.

 

Where can I get tips on how to diagnose specific sensors?
