Brantz Dividing Interface for Universal Wheel Sensor
Select the BROWN (positive) wire and connect it to the spade connector on the SENSOR side of the Pre-Scaler labelled BLUE. Connect the BLUE wire from the wheel sensor directly to the GREEN spade connector on the SENSOR side of the Pre-scaler. The rotary switch on the interface sets the pre-scale ratio/dividing multiple i.e. set on 2 it will divide the number of pulses from the vehicle to the Brantz Meter by 2. It should initially be set on 1. The lower the pre-scale ratio, the more accurate the meter will be, but this facility is provided to compensate for very high pulse rates which would take the Brantz Meter out of its normal calibration range of up to 999 (or 9999 for the Laser 3). If the meter calibration figure is out of range, rotate the arrow (using a very small screwdriver) up to 2 or (rarely) greater, and then re-try the calibration. N.B. The ratio must always be greater than 0. Some models have a rotary SENSITIVITY control, this is normally set to a mid range position, this is with the arrow is pointing at the central right-hand connector. The sensitivity can be adjusted to accommodate different threshold levels of the speed pulse.
Brantz/Retrotrip Instrument.
For modern rallies, we recommend the Brantz International trip meters. The International trip meters feature large light-emitting displays, 15 mm (0.6 inches) tall. The Brantz International 1 is ideal for road rallying and club-level stage events, while the Brantz International 2 provides a comprehensive solution for professional rally drivers. The Brantz 2 ‘S’ Pro includes an exceptionally accurate speedometer. These models are calibrated electronically and typically used with a wheel or prop shaft sensor.
