Extension set contents:

Magnet (2 pcs)
For attaching temperature sensor to vehicle
Mounting bracket (2 pcs)
Angle bracket for sensor
HMP holder
For air temperature and humidity sensor HMP113 (not needed in MT10 mounting)
Cable, 5 m (16 ft 4 in)
For connection between MD30 sensor body and HMP113
Cable, 3 m (9 ft 10 in)
For connection between MD30 sensor body and either MT10 or HMP113
Sealing tube (4 pcs)
For cable ends
Screws (8 pcs)
Sockethead Torx screw M4×8
Screws (4 pcs)

Install one of the temperature sensors or both separately. Recommendations for optimal performance:

  • HMP113: mount to a location with good air flow and away from heat sources such as car engine.
  • MT10: mount under the vehicle and away from heat sources, reflections from sky, and sunlight.

WARNING Disconnect power from the sensor before you start.
Make sure that there is grease on the cable connector. If not, apply a generous amount of MD30 connector grease (12475SP) to the cable connectors.
  1. Loosen the 4 screws that hold the temperature sensor in place and remove the sensor, pull the air temperature and humidity sensor (HMP) through the holder, and disconnect the sensor cable.
  2. Assemble as shown in the following figures.

    Use the provided screws. Use the sealing tubes at both ends of the cable.

    For the air temperature and humidity sensor HMP, put the existing holder back to MD30 to protect the cable connection.

  3. Select a place for the sensor, for example under the vehicle or under the side mirror of the vehicle.
  4. Attach the cable with cable ties to the vehicle.
