Brantz International 3 Pro Operating Instructions

Wiring (Not Applicable of you are using your meter in conjunction with a BR57 & BR45/BR47):
Power:
•
Connect up to the vehicles 12 volt power supply as directed by the label
•
on the BLACK POWER CABLE coming out of the base of the tripmeter or
Plug Kit (BR43). This is BROWN to the POSITIVE Terminal and
GREEN/YELLOW to the NEGATIVE Terminal.
Connect straight to the vehicles battery posts via a 2 Amp fuse (Not
•
Provided - Available from Brantz) on the live wire, usually the BROWN
on +12V cars, however on Positive Earth vehicles it is customary to fit
the fuse to the live GREEN/YELLOW wire.
Sensor:
•
The Sensor is connected to the GREY CABLE coming out of the base of
•
the tripmeter as directed by the separate sensor instruction sheet
showing how to wire the exact type of sensor you have chosen.
Calibration:
The Tripmeter is calibrated to be accurate on any vehicle fitted with any type of Brantz Sensor and using any wheel size or
•
gearing by means of the three push-wheel switches marked 'CALIBRATION'.
If the Tripmeter is to measure in hundredths of a Kilometre/Mile the push-wheel switch needs first to be set to 100.
•
At the start of an accurately measured Kilometre/Mile, press the Zero button to ensure the counter reads 00.00.
•
Drive the measured distance and stop accurately at the end of the distance – Note the figure that comes up on the readout.
•
(This is the Calibration Figure for this particular vehicle)
Enter this figure into the calibration push-wheel switches on the front of the tripmeter. e.g. If the readout is 05.67 set the
•
push-wheel switches to 567. N.B. If the readout is greater than 09.99 a Pre-Scaling Interface (BR5)/Dividing Pre-Scaler (BR5-
2A) is required – please contact us on 0044 (0) 1625 669366 or Email:
The accuracy can be confirmed by re-running the measured distance after zeroing the readout, the meter should read exactly
•
01.00
If several wheel sizes and gearings are available for the vehicle; repeat the calibration procedure for each combination and
•
note down the different calibration figures.
Use/Controls:
The tripmeter is switched on by use of the rocker switch on the base of the tripmeter.
•
When the switch is moved from position '0' to the 'I' position the meters digits will light up. N.B. A battery charger is not a
•
suitable power source to test the tripmeter.
The RED button on the remote reset box, when pressed will zero the INTERMEDIATE DISTANCE readout.
•
The upper toggle switch on the front of the tripmeter marked 'Freeze Total'/'Zero Total' has 3 positions and will normally be
•
in the middle position.
If the switch is pushed UP the TOTAL DISTANCE readout will be FROZEN, when the switch is returned back to the
•
middle position the readout out will continue from the Frozen value. (This facility is useful if the competitor wishes
to correct (Pre-Set) the Total Distance readout to a value that he knows should be displayed at a certain point on the
road. The readout can be unfrozen at this point on the road so that the correct value is displayed from this point on.
This facility is also useful if the Total Distance readout is too high; the readout can be frozen and then the vehicle
driven without the displayed value increasing).
If the switch is momentarily switched DOWN this will Zero the TOTAL Readout.
•
The lower toggle switch on the front of the tripmeter marked 'Count +'/'Count –' allows the tripmeter to count upwards or
•
downwards.
The STEP control knob is to edit the TOTAL DISTANCE readout value. Turning the knob clockwise a click will be felt and the
•
TOTAL DISTANCE readout will start to count either up or down depending on the position of the Count +/Count – toggle
switch. (This facility is useful to align the Total readout value to any given value , say, by the organisers handbook at a certain
point).
The STEP control can be used with the FREEZE switched ON.
•
The STEP control should normally be in the off position that is turned fully anti-clockwise until a click is felt.
•
The three digit 'SPEED' readout will display the vehicles current speed to one decimal place in the units to which the
•
tripmeter is calibrated i.e. calibrated in miles, shows mph or calibrated in kilometres shows kph.
