OWNER’S MANUAL

APM /

Before using the bit Tune, please refer to all instructions contained in the manual. We recommend to closely 

follow the instructions. Failure to comply with these instructions could result in unintentional injuries or damage to 

equipment or devices connected to it.

1. 

In order to use the 

APM

 measurement tools, you must install the software on a personal computer running 

  Windows XP, Windows Vista or Windows 7/8/10, with a 1.5 GHz processor or higher, 1 GB of RAM and a graphics 

  card with minimum resolution of 1024 x 600 pixels.

Remarks:

 

-

 The APM PC software might show malfunctioning with some PCs manufactured before 2008 even with 

      processors running at higher speed than the minimum required. It is recommended to check using 

      “Windows Update” and make sure that the available updates are installed in the PC. 

  

-

 Before performing the measurements, check that the Antivirus is not scanning the PC. If you experience 

      any problems, it is advisable to disable the Antivirus, even if it is not scanning the PC, and close any other 

      running programs.

2.

 Please use only the specific power adapters provided in the package (bit Tune +APM).

3.

 For use in the car please check that the vehicle’s electrical system has a supply voltage of 12 VDC with negative 

  to ground. If you are using the network adapter, select the power supply connector suitable for the country of use 

  (provided in the bit Tune package).

4.

 Do not perform any measurements in the engine compartment and in locations exposed to water, excessive 

  moisture, dust and dirt.

5.

 Take measurements in places where the temperature does not go below 0 °C (32 °F) and does not exceed 55 °C (131 °F).

6.

 Make sure that the positioning of the device does not interfere with the proper functioning of the car’s electrical or 

  mechanical devices.

7. 

Make sure you do not short the power cord during the measurement.

8.

 In order to facilitate the measurement, route the cables the best possible way, using cables supplied with the product 

  and referring to instructions provided in the USER MANUAL.
