The
tripmeter is switched on by means of the switch on the base
of the meter. The switch is moved from the 0 pressed position
to the 1 pressed position. The meter digits will light up
when the power is ON. Controls: The remote reset button
will zero the lower distance display. The metallic switch
on the face of the meter has three positions, and will normally
be in the central position. If this switch is moved upwards
to the FREEZE position it will stop the top TOTAL display
from incrementing. This facility is useful if the competitor
wishes to preset the TOTAL distance figure to a certain
value which will be reached at a known certain point on
the road, or the TOTAL reading is too high and the vehicle
needs to travel a distance without the TOTAL distance being
increased. The downward position of this switch zero's both
readouts on the Clubman version of the Brantz International
2 meter and just the top TOTAL readout on the 'Pro' Brantz
model. This switch should be operated momentarily when the
tripmeter is first switched on. The STEP control above the
three-position switch is to edit the TOTAL readout value.
It is a rotary control which is normally fully anti-clockwise
until a 'click' is felt. Turning this control clockwise
will cause the TOTAL readout to step itself which enables
the competitor to set the TOTAL readout to any figure. This
facility is useful to align the TOTAL readout value to a
value given, say, by the organizer's handbook at a certain
point. The control marked + and - is fitted to the 'Pro'
models and allows the tripmeter to count upwards or downwards
(+ is incrementing, or upwards). Calibration: The meter
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 thumbwheel switches on the lower right
hand corner marked CALIBRATION. If the meter is to show
hundredths of a kilometre then the thumbwheel switches are
first set to 100. Find the start of an accurately measured
kilometre and momentarily press all the reset (zero) controls.
Drive the measured kilometre and stop accurately at the
end of the distance. Note the figure which has come up on
both readouts. This is the calibration figure for this particular
setup of the vehicle. Enter this figure onto the calibration
thumbwheel switches. The accuracy of the meter can be confirmed
by turning the vehicle around and traveling back over the
measured kilometre. The measured kilometre should be read
by the Brantz very accurately as 1.00 kilometre. To calibrate
in hundredths of a mile, follow the above calibration procedure
exactly, but substitute the word 'mile' for the word 'kilometre'.
If several wheel / tyre sizes and gearings are available
for the vehicle then repeat the calibration procedure for
each combination & note down the different calibration
figures. Long distance events: Certain of the Brantz 'Pro'
models which contain the letter 'D' in their serial number
can shift the decimal place of the top TOTAL readout one
place to the right so that the TOTAL will indicate 999.9
kilometres or miles which is a useful facility for certain
international events. The tripmeter cannot change from one
mode to the other after being switched on. On power-up,
the tripmeter normally will be in standard mode (99.99)
kilometres or miles, but if the T.ZERO switch is held in
the downwards (zeroing) position WHILST THE METER IS BEING
SWITCHED ON then the normal mode will be reselected.
