GUIDE TO TESTING
General guide:
The START key starts the motors or motor as appropriate. This will only
happen with a car in the rollers as shown by the green Ready indicator
lamp being illuminated.
After START is pressed and while the motor(s) is getting up to testing
speed, the digital display will show rotating icon(s) to confirm which
wheel(s) is being started. Once this icon disappears, test actions or brake
force measurements can be taken.
Four actions will stop the rollers; if the STOP key is pressed, the car
leaves (even temporarily) one of rollers sets, wheel slip is detected or the
safety switch is activated.
With a car on the rollers and the rollers not running, one (or two) of the
green indicator lights LUp, LDn, RUp, RDn will flash to show the direction
in which the wheel(s) will be driven. Once the motor is started, the
flashing light will be stay on.
As the brakes are applied and a wheel approaches the pre-set slip limit,
the respective red
Lock
indicator will flash.
Any measured value will remain on the scale display (or DDsp) until the
OK button is pressed to accept the result. The pointer(s) will then be
returned to zero.
If the brakes are cold or wet, take the opportunity to apply brake several
times to warm up and/or dry brakes while the wheels are being centred.
Individual sections of the MOT procedure can be repeated if
unrepresentative readings have been obtained or the process is
interrupted for some reason. Simply press the START key again and
repeat the test section, only the results taken during the last sequence
will be stored when the OK key is pressed.
The normal testing method follows the MOT tester’s manual sequence but
the rollers can be used in Manual mode or specifically for testing one
wheel of motorcycles or three wheel vehicles – see later sections.
