Page 11: Product Overview
Optical Laser Height Sensors Type CHFA… 3. Product Overview 3.1 General Description HF laser height-sensors are designed for non-contact distance measurement for vehicle dynamics testing. Laser height-sensors of the HF series use the principle of optical triangulation. A visible red laser is focused onto the road surface. -
Page 12: Features
Further fields of application are for instance uplift measurements, spring deflection, dynamic tire flat spotting, tire lift-off (Fishhook Test). Two HF sensors mounted at the wheel enable dynamic camber angle measurement (refer to the Kistler DCA System). 3.4 Accessories Included Accessories Type/Art. -

No. KCD15408 To assure proper function of the suction holders, the mounting area must be free of grease, oil, dust and other contaminants. - Page 21 Optical Laser Height Sensors Type CHFA… Fig. 6: Assembling stabilizer element and suction holder unit Assemble the suction holder unit and the stabilizer element. Fig. 7: Removing the protection caps Remove the protections caps and place the complete suction holder unit at the vehicle body so that it will be within the required measuring range (see Chapter 4.1, Specifications).
- Page 22 Setup and Connection Fig. 8: Pushing the pumping piston When the suction holder unit is correctly positioned, press the suction holders – one after the other – firmly against the vehicle body to flatten the rubber pads against the body surface. Then, push the two pumping pistons repeatedly until the red warning ring is not visible any more.
- Page 23 Optical Laser Height Sensors Type CHFA… Monitor the pumping pistons during use to be sure that the suction pads adhere firmly! If the red warning ring is going to become visible, the suction pads are going to loosen. In this case please interrupt use and push the pistons until the red ring is invisible again.
- Page 24 Setup and Connection Fig. 11: Mounting the sensor Attach the HF sensor to the mounting plate. Insert the sensor mounting screws through the mounting holes in the sensor, then into the holes of the mounting plate and tighten the screws with an allen wrench (size 4 mm). It is definitely recommended to use the polyamid washers (also included in the scope of delivery).
- Page 25 Optical Laser Height Sensors Type CHFA… Fig. 13: Affixing the safety line Wind the safety line around the stabilizing element and mount the metal clamp. We recommend to protect the painted surface in this area with an easy-to-remove tape and to remove it right after the measurement.
- Page 26 Setup and Connection Fig. 15: Securing the safety line (at the window in this case) Fig. 16: Connecting the sensor Connect the signal cable to the sensor and route it into the interior of the car to the sensor electronics unit. Use cable ties to fix the signal cable at the mounting unit.

Insert the sensor mounting screws through the mounting holes in the sensor, then into the holes of the mounting plate and tighten the screws with an allen wrench (size 4 mm). It is definitely recommended to use the polyamid washers (also included in the scope of delivery).
- Page 31 Optical Laser Height Sensors Type CHFA… Fig. 24: Connecting the sensor Connect the signal cable to the sensor and route the cable into the interior of the vehicle to the sensor electronics device and connect it there too. Now, your HF sensor ready for use! In most cases it will not be necessary to use a safety line as the magnets hold automatically fast to the (metal) vehicle body.
