RPM SENSOR
The RPM sensor comes standard with every Unipro Laptimer. We use an active sensor to ensure
the best possible signal from all kind of engines. Mount the sensor with care. You do not want it to
fall of during a race. If that happens, the Laptimer will turn itself off after 5 minutes and you will
no longer be able to see your lap times.
Mount the sensor with at least two strips.
The RPM sensor is mounted in the middle of the ignition
cable with at least two strips.
The ignition on a gokart is the worst source of electrical
noise and it is therefore a good idea to keep the RPM cable
away from any other cables.
Please do not let the RPM cable touch the cylinder or the
cylinder head because it can tear the isolation and shield
and cause disturbance. The most important issue is to
separate the RPM cable from the ignition cable just after
the sensor. This is clearly shown on the picture. Do not let
the two cables run together!
The cable is mounted in the connector marked RPM on the main box. Tighten the connector
hard with your fingers.
RECEIVERS
The Unipro Laptimer supports all kind of receivers. The different receivers are good for different
things. If the track has a loop, we recommend using the Loop Receiver.
AMB Loop receiver
Mounting the Loop receiver.
The Loop receiver is mounted as low as possible on the left
side of the seat. Drill a 6.5 mm hole from the inside of the
seat. The distance from the underside of the Loop receiver to
the asphalt must not exceed 100 mm.
The Loop receiver is mounted parallel with the seat and needs
to point backwards against the rear axle. Make sure, that
nothing comes between the receiver and the track.
Use plenty of strips to secure the cable to the Main Box.
When the receiver is mounted, the cable is fixed to the middle of the kart, all the way to the
Main Box. Use plenty of strips to secure the cable.
The cable is mounted in the connector named RECV 1 on the Laptimer. Tighten the connector
hard with your fingers.
