Glossary

AVG_FWD:

The average deceleration in the forward direction (vehicle movement direction). When you put your foot on the brake pedal, the vehicle starts to decelerate and test is triggered by the vehicle decelerating by more than 0.1g. Brake meter samples the deceleration of the vehicle in the direction of movement every 0.01 second. Finally brake meter averages all the samples and displays the value. If the F vector in g is multiplied by 100, you will get the reading in percentage. For example: 0.51(g) x 100=51%.

MAX_FWD:

The maximum deceleration is forward direction. The largest deceleration value during whole vehicle deceleration period is displayed.

AVG_VER:

The average deceleration in vertical direction. Brake meter samples acceleration of the vehicle perpendicularly to the vehicle movement direction every 0.01 second. Brake meter averages all the samples and displays the value. IF the V vector is g is multiplied by 100, you will get the reading in percentage.

MAX_VER:

The maximum acceleration in vertical direction. The largest acceleration value during whole vehicle deceleration period and is displayed.

AVG_LAT:

The average acceleration in lateral direction. Brake meter samples acceleration of the vehicle laterally to the vehicle movement direction every 0.01 second. Brake meter averages all the samples and displays the value. If the L vector in g is multiplied by 100, you will get the reading in percentage.

MAX_LAT:

The maximum acceleration in the lateral direction. The largest acceleration value during whole vehicle deceleration period and is displayed.

Speed:

The velocity at the time that you put your foot on the pedal and the vehicle starts decelerating. The vehicle should should be completely stopped within 10 seconds after deceleration.

Stop Distance:

The distance from the moment of the start of the deceleration the vehicle to the time that the vehicle has stopped.

Side Distance:

The distance of the vehicle sideways shift in meters or feet.

Save:

If you download test data to the PC or recall the test result, you need to save the test to no-volatile memory. You can switch off brake meter after the test without losing the test data.

Invalid Test:

Brake meter starts to test the deceleration when you put your foot on the pedal. If the vehicle is not stopped within 10 seconds, you will see “Invalid Test”. Press any key to return to main menu.

Datalog:

Downloading the test data from brake meter to the PC.

Handshake:

The PC and brake meter exchange testing data to check the communication between the PC and brake meter.

Comm Error:

You will read this message if handshake between the PC and brake meter is faulty. If this occurs, brake meter will automatically return to main menu in 20 seconds.

Time out:

You will read this message if the PC has failed to read from brake meter within 20 seconds after you press YES from the menu ‘Datalog?’ and ‘Calibration?’. The brake meter will automatically return to main menu.

Battery Life:

If you leave brake meter on and do not press two keys, brake meter will turn off automatically in 10 minutes.

Clock:

Brake meter shows standard date and time and date and time can not be changed.
