TEXA’s revolutionary RC3 not only keeps engine RPM and temperature under constant control but also serves as an ECU scanning tool. It therefore allows mechanics to perform two types of test using just the one tool.
The RC3 (Revolution Counter 3) interface can read data in three different ways: using an induction clamp with piezoelectric sensors, using a microphone with the residual battery signal, or directly from the OBD socket (on vehicles with the necessary protocol).
 When plugged into the OBD socket to measure engine RPM and temperature, RC3 reads data directly using EOBD protocol, so there is not even any need to open the bonnet.
RC3 can also be used in scan-tool mode; connected to the EOBD socket, it can read the parameters defined by this standard in accordance with new emission control procedures.
