TRANSDUCER CALIBRATION
The KEI-095 brake tester works by comparing the angle on the brake pedal level transducer to
the angle of the floor transducer. The angles must be the same from each transducer. Because
the pedal travel and deceleration values are derived from these angles, the angles must be
accurate for the system to be accurate. Periodic re-calibration of the system is necessary.
Calibration re/- four precision known angles, and zero, to set the pedal and floor
transducers to, and a precision known weight for the force transducer.
To calibrate the Angle Transducers:
1.
Connect the KEI-095 brake tester to a 12.6 to 15 volt, 500 ma power supply. Connect
all transducers to their brake tester ports.
2.
Turn on the brake tester. Press any key to display the main menu.
3.
Press the 0 key to enter the Start Test Menu.
4.
Press the 1 key to set the pedal length to
07.00”
. This is required to calibrate the
transducers using Cal Stand KE095CS. Press * key to return to the main menu.
5.
Press the 1 key to enter the Calibration mode.
6.
To prevent unwanted access to the calibration modes a numeric code must be entered.
Enter "1", "2", "3", "4" on the keypad. The calibration menu will be displayed.
7.
Press the 1 key to calibrate the both transducers at the same time. This is the generally
recommended transducer calibration mode. Press the 2 key to calibrate each transducer
individually, Press the 3 key to calibrate the pedal force transducer.
8.
The display will show the current raw transducer output. For the angle transducers,
place the calibration stand on a level surface and adjust the transducer so that the
reading is as close to zero as possible. Press the 1 key when close to 0.00 degrees.
9.
The display will instruct the operator to set the angle transducers to a known negative
angle. The recommended first angle is -60 degrees, however any angle 0 to -99.999
degrees can be used. Set the transducers to the angle and enter the 5 digits of the angle
(60.000)on the keyboard.
