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.
NTCs are the most used temperature sensors in the industry, which vary their resistance value as a function of temperature.
The cars have at least one of these sensors, and they get to have 4 or 5. A failure in this sensor can cause a high consumption of fuel.
These sensors are classified by their resistance at 25 ° c (77 ° f).
You can use the HMP1 to test this type of sensors.
1) Connect a test cable to the TPS1 input of the device. But do not make contact with anything.
Caution: Disconnect the sensor from the cable that goes to the ECU before measuring the sensor
2) Connect the 12v and wait for the menu to appear on the screen. 3) Press the "+" and "-" buttons until you see "NTC" written.
4) Press OK and the following information will appear on the screen:
NTC
You are testing NTC sensors
1.9k
Current value of the sensor (measured resistance)
10k
Sensor value at 25 ° c (77 ° f)
67
Temperature that the sensor accuses in degrees centigrade (152.6 ° f)
The temperature can be displayed in Celcius or Farenheit by changing the configuration.
5) Use the "+" and "-" buttons to change the sensor type.
