ETCS Inclinometer Helper V2

Pitch Measurement

Installation limit: ±2°. Enter the absolute value from the inclinometer and select the matching triangle.

Track Slope Measurement

Measure point 1: below the ETCS cubicle on its vertical axis.
Measure point 2: 1.5–2 m to the right of point 1.
Measure point 3: 1.5–2 m to the left of point 1.
Points 4–6: same positions as 1–3, but on the second rail.

Inclinometer Manual for Clinotronic Plus
  • Preparation Outside the Vehicle
    • Place the inclinometer on a stable horizontal surface (e.g., a table) and turn it on using the ON/MODE button.
    • Use the ON/MODE button to navigate to the ZERO menu. The display should show 00.00.
    • Press the ENTER-HOLD button and do not move the inclinometer. A measurement will take place over 10–30 seconds.
    • Once the measurement is complete, a value will be displayed. Rotate the inclinometer by 180° and repeat the previous step.
    • After the measurements are complete, the device will automatically switch to the ABSOLUTE mode.
  • Track Slope Measurement
    • Go underneath the vehicle. If the inclinometer has turned off, turn it back on with the ON/MODE button — it will return to ABSOLUTE mode automatically.
    • Measurements are assumed to be taken from outside the vehicle towards the inside.
    • Go under the section of the vehicle where the cubicle is located and measure at least three points (calculate the arithmetic mean) approximately 1 meter apart on the rail head (for 20Ev, all measurements should be between the wheels of the first bogie).
    • If the symbol < appears on the inclinometer, the left side is lower than the right.
    • If the symbol < appears, cab A is lower than cab B, and the gradient is negative (value multiplied by 10000).
  • Relative Mode Calibration and Radar Measurement
    • Switch to RELATIVE mode using the ON/MODE button. The display should show 00.00.
    • Place the inclinometer on the rail head and press the ENTER-HOLD button. Wait approximately 15 seconds until the value 0.00 appears.
    • At this point, hold the inclinometer against the radar and start measurements.
    • Measure the radar at least three different points (calculate the arithmetic mean of all points) along the center of the radar.
    • Measurements should be taken from the side without a metal plate; the pointed end of the radar should be on the left side of the operator.
    • If the symbol < appears on the inclinometer, the left side is lower than the right, and vice versa.
    • If the radar's pointed end is downward, the coefficient value is greater than 10000 (e.g., 10027).
    • If the radar's pointed end is upward, the coefficient value is less than 10000 (e.g., 9982).
    • The pitch must not exceed ±2°.
    • The radar should also be measured from the front, but precision is not as critical here (Tilt max ±0.5°).
  • After Measurement
    • Record both the OLD values and the new ones in the protocol.
    • Apply the measured and TRANSLATED values to the DMI.
    • After entering the values and successful calibration, restart the EVC.
