1.1 Application and measurements
Decelerometer is used for measurements of overall brake decelerations of traffic vehicles.
The value of deceleration is measured, as well as its dependence on the controlling force
applied to the brake pedal, or its dependence on the air pressure in the air pressure
brakes. The results of measurements are the graphical records time related the numerical
calculated average value of overall deceleration and the average value of control force or
the average value of air pressure.
The following three options can be ordered:
- Decelerometer only
- Decelerometer with external sensor for controlling force applied to the brake pedal
- Decelerometer with external sensor for air pressure in the air pressure brake system
The measurement of the controlling force applied to the brake pedal and the measurement
of the air pressure in the air pressure brakes is possible only with the external force sensor
or with the external pressure sensor. After the selected sensor is connected, the
Decelerometer will be configured automatically. The external sensors are supplied as
accessories.
External sensors from different Decelerometers are not exchangeable
without the manufacturer’s calibration.
The measurement is very easy. The instrument must be placed onto the vehicle whereas
the arrow on the instrument shows the direction of travel. With the levelling screws and
built-in levelling libel the instrument is adjusted into exact horizontal position. After
switching-on, the display scrolls the instructions. When the calibration is finished, the
vehicle can be set into the motion. The measurement will start by pressing the starting
button. Than the vehicle is slowed-down until it stops by its own braking system. The
wheels are not allowed to block. The maximal values appear at the display and the
detailed report is printed. The results of measurements will remain in the internal memory
as long as the power is switched-on.
1.2 Specifications
Design and specifications of the Decelerometer are based on the regulation of Ministry of
transport, “About regular technical inspections and emission measurements of the road-
bound vehicles “.
Measurement Ranges:
- Braking deceleration 0 - 20 ms-2
- Controlling force applied to the brake pedal 0 - 1000 N
- Air pressure in the air pressure brake 0 - 1 MPa
Accuracy of the measurements:
- braking deceleration ± 3 %
- controlling force applied to the brake pedal ± 35 N
- air pressure in the air pressure brake ± 25 kPa.

1.3 Decelerometer accessories and options
The Decelerometer contains the microcontroller supported measuring circuits, set of
options and accessories which facilitate the measurements:
- Decelerometer OC3010
- External start button
- AC adapter for NiMH battery
- interface cable for connection to PC computer
- CD with program for PC (Windows)
- Extra paper for the printer
- Users manual
- Carrying Case
Option (extra order)
- Pressure sensor 1MPa with a cable
- Force sensor 1000N with a cable
- Pressure hydro sensor 20MPa with a cable
- Weight sensor 8T with a cable
The use of the pressure or the force sensor depends on the application. The interface
cable to PC computer may be connected. The Decelerometer may be configured and used
as stand alone unit or as a data acquisition system for collecting the data and transferring
them to a PC. With the help of external start button the measurement can be initiated by
the operator of the vehicle.

1.4 The principle of measurement
The measurement is performed by simultaneous recording the deceleration and the
controlling force applied to the brake pedal or by recording of the vehicle deceleration and
the air pressure in the air braking system. All data are stored in the internal memory after
the button Start has been applied. The measurement of the deceleration, the controlling
force applied to the brake pedal and the air pressure in the air brakes is realised with the
build-in deceleration sensor, the force sensor or the pressure sensor. At the end of the
measurement the maximal values are shown at the display and a detailed report is printed.
During the printing the calculation is performed for the average value of the overall
deceleration, the average value of control force or the average value of the air pressure.
Before the measurement starts, the recording interval has to be set. The range of setting is
from 1 to 50 seconds (5 to 300 seconds for OC3010XL). An averaging filter is available
with selectable filtering constants from 0 (no filter) to 10 (long time constant).
The measurements can be initialized:
- Starting button MEAS
- External starting button
- Setting the threshold value
or combination of the above.
The recording clearly shows whether the measured smallest average value of the overall
deceleration is as prescribed in the vehicle manual and whether the controlling force
applied to the brake pedal or the air pressure have achieved the required values.
The results of measurements (up to 128 data sets) will be stored in the memory and might
be printed. With the help of the supplied program, the records can be downloaded to a PC.
After each measurement the Hydro sensor or the Weight sensor can be connected and
used. Press the button MEAS again. After the display shows steady reading, press MEAS
again. The pressure or weight measurements are stored.
1.5 Auxiliary Sensors
For measurement of Forklifts the hydraulic sensor can be used connected to the forklift
hydraulic installation. For weight measurement of the Forklifts an external weight sensor is
optionally available.

1.6 Report printing
When the measurements are stored, the report can be printed. The record contains the
company’s head (can be disabled), time and date, and the measured values and the time.
The maximum deceleration value and the duration of the measurement will be printed as
well. After entering the time interval, the average value of overall deceleration and the
average value of the force or the air pressure will be calculated and printed.
If Hydro sensor or Weight sensor is used, their results will be printed as well. Two lines of
text are added to the printed report, containing the identification of the vehicle and the
confirmation of the measurement.
The printing on the 57.5mm wide paper is in ink. This will guarantee a long lasting quality.
The printing of one report takes about 15 seconds. The report may be printed several
times. The interval however in which the average values have to be calculated must be
entered all the time. The reports of previous measurements may be printed more times as
well.
