The high pressures in the common rail system, which usually exceed 1000 bar, make it difficult to measure the actual pressure.
Most common available testers measure the pressure based on the signal from the pressure sensors of the vehicle.
If the pressure sensors are defective or incorrectly adjusted, can it happen that incorrect values are read off. This common rail tester measures the actual pressure with an analog 2000 bar pressure gauge. The gauge is made of
- the tester is supplied with two different sets of flexible hoses and
adapters so that the tester can be used universally
