Frequently Asked Questions

What is included with the Chassis Height Measuring System?

The CHMS contains four sensors, one tablet, one wall power cube, one charging cord, and a custom carrying case. Each CHMS sensor has one thermistor, two sensors, one laser, 1 LED, one button, and two magnets (if the magnetic floor option is chosen).

How to use the CHMS sensor?

Click the grey power button once to turn on each sensor. The LED will flash indicating it is powered on. Hold the grey POWER button to align the sensor using the laser. Click the button three times to zero each sensor. Click the Button five times to power off the sensor.

How do I take measurements with the chassis on the ground? 

Power on the tablet and four sensors and launch the CHMS App. To measure from the ground up, position the sensors on the ground using the laser to align each sensor under the frame rail for all four corners of the chassis. If you have the magnetic floor option, attach the sensors to the frame rails to measure from the chassis down. Tap TAKE READING on the tablet. Make setup adjustments as needed. Tap TAKE READING again to display chassis heights adjustments.

How do I take measurements with the chassis on the scales? 

Power on the tablet and four sensors and launch the CHMS App. Level your scales side to side and front to rear (this is imperative to ensure accuracy and repeatable results). Position the sensors on the ground and roll the chassis of the scales. Place a straight edge or level on each scale pad extended over each sensor (using the laser for alignment with the straight edge as needed). Click the grey POWER button three times to zero the sensor (the LED will flash three times and an audible signal will indicate “corner zeroed.” Zero the sensors for the three remaining corners. Tap SAVE ZEROS, name your saved data, and select OKAY. To measure from the ground up, roll the chassis onto the scales and position the sensors on the ground using the laser to align each sensor under the frame rail for all four corners of the chassis. If you have the magnetic floor option, attach the sensors to the frame rails to measure from the chassis down. Tap TAKE READING on the tablet. Make setup adjustments as needed.
