The HMP1 born as electronic body throttle tester.
But early grown new functions, until convert it in the most complete tool in the market for sensors and actuators.
Today you can get 25 tools in a single device and maintain a easy usage way.
Thanks to their screen you can read clearly all information coming from sensors.
No software, no updates, no montly fees.
With a Heavy Duty manufacture for a long lifetime.
Also known as a Lambda probe, it is a sensor that measures the state of the fuel mixture.
It is understood as rich when the proportion fuel:air indicates that there is more fuel than required, and is understood as poverty when the proportion fuel: air indicates lack of fuel (excess air).
Because this sensor only work when the temperature is higher than 300 C (572 F) you will need the engine running to test it.
Normally during the operation of the motors this value goes up and down from 0.2v to 0.8v once or twice per second.
1) Connect a test cable to the TPS1 input of the device. But do not make contact with anything.
Care: make sure that no more than 5v enter before the test
2) Connect the 12v and wait for the menu to appear on the screen. 3) Press the "+" and "-" buttons until you see written "Lambda".
4) Press OK and the measured voltage will be shown and a graphic bar.
