Brantz International 1 Pro Setup 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 from zero, 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.
If you are using a Dual Sensor Switch (BR49) make a note of the calibration figures for both sensors A and B.
•
Use/Controls:
The tripmeter is switched on by use of the 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 push-button on the front of the tripmeter marked 'ZERO' when pressed zero's the readout.
•
The small toggle switch on the front of the tripmeter marked 'Count +'/'Count –' allows the tripmeter to count upwards or
•
downwards.
For Long Distance events the decimal place on the TOTAL display can be shifted from 00.00 to 000.0, by:
•
With the tripmeter OFF; hold down the Red Zero button and switch the tripmeter ON.
•
The tripmeter will return to it's default 00.00 when the unit is switched Off and On again.
•
If the rally organiser has laid out an 'official distance' or you wish to make your tripmeter read the same as the rally organisers
distances then the following instructions apply for calibration:
Enter 100 (C) into the push-wheel calibration digits (N.B. If the official measured distance is greater than 20 miles you would
•
need to enter a much higher figure for C e.g. between 399-999).
With the Total and Intermediate Displays showing Zero drive the total official measured distance i.e. 4.8 (D) miles and note
•
down the readings i.e. 21.98 (T) (this should be identical on both Intermediate and Total Displays)
Now use the following formula:
•
e.g.
(21.98/4.8) x 100
=>4.579 x 100
=>457.91
So enter 458 into your calibration push-wheel switches.
To confirm the figure, re-drive the measured distance and your displays should show the official distance e.g. 4.8 miles.
