2.6 Fuel consumption sensor:

   Power supply DC＋12V,

   Sensor output pulse signal: Low level 11V,

   Pulse equivalent approximately: 0.1 ml/pulse (If the power supply is DC＋5V,

   Output pulse signal: Low level4.5V).

3. Test mode

There are the following two test modes:

 1. Comprehensive test (displacement sampling method): (Preset before testing)

   Sampling frequency: 1cm～1,000.00cm

   Measuring area length: 10,000.00cm～200,000cm

 2. Special test (time sampling method ): (Preset before testing)

   Sampling frequency: 0.01 seconds～60 seconds

Note: 1. Torque test, tensile test, and fuel consumption measurement can be carried out separately or in combination

   2. Test data output format:  1. In the displacement sampling mode, the data collected from the other 25 channels should be selectively output.

                       2. In the time sampling mode, the data collected from the other 25 channels should be selectively output.
