| This
Speedtable (VERSION A5) allows competitors to quickly program
any speed to one decimal pace. Keeping the car's tripmeter
matched to the speedtable figure creates very accurate average
speed attainment. The unit is battery operated, has backlighting,
beeps at each increment if you wish it, and needs no connection
to the car. Specifications: 4 digit large LCD readout. 4 mechanical
push-switches to calibrate to any speed 0.1kph to 999.9 mph
(either mph or kph). Solid state backlighting. Audible beep
on or off. Speed to one decimal place. Small (10cm long) pocket
size case. PP3 (9 volt) alkaline battery operated. A quality
battery lasts for several days continuous use. Remove it if
the unit is not to be used for long periods. Use of the beeper
and backlights reduces battery life. The battery condition
is indicated by the brightness of the backlights. Set the
rotary switches to the required average speed to one decimal
place (ie 0352 = 35.2 mph or kph). These switches permanently
reassure that the speed is correctly programmed. The Z membrane
switch zero's the readout and enters the set speed into the
calculation. If you keep the vehicle at the speed which matches
the tripmeter to the speedtable then the average speed desired
will have been achieved. If the tripmeter is lower than the
speedtable then increase the speed of the vehicle. If the
tripmeter is higher than the speedtable then slow down the
vehicle until the figures match. The R button enters the desired
average speed from the rotary switches without zeroing the
readout. This enables speed changes to be achieved without
zeroing the tripmeter; pre-enter the new speed onto the rotary
switches, and press R at the point where the new speed starts.
The new speed calculations will commence from that point.
If, after reaching the next control, the timing Marshal advises
that a new average speed should be used RETROSPECTIVELY (ie
from the previous control) then enter the new average on the
rotary switches and momentarily press the 'M' button. A new
target tripmeter reading will appear on the readout.. |
| Special
Settings |
|
| The
machine is of course only a timer. Used on setting 0360 it
simply counts seconds. Used on setting 3600 it counts seconds
to one decimal place. Used on 0006 it counts minutes. Used
on 0600 it counts minutes to 2 decimal places. Used on 0001
it counts hours to one decimal place. Used on setting 0010
it counts hours to 2 decimal places. |
| The
Marshalling Clock |
|
| The
Marshalling Clock (available in version A5 only) mode is available
by holding the 'H' (Hours) button pressed whilst switching
the clock 'ON' by the power switch in the rear battery compartment.
It features hours, minutes, seconds and hundredths of a second,
spread over two uses of a large format four digit LCD screen.
The primary function of a marshalling clock is to hold the
time of day for logging purposes when a competitor completes
a stage of a competition, then restore the current time of
day to the readouts following the noting of the competitor's
time. A bonus feature is that this clock holds a memory of
the previous frozen time, just in case the screen freeze is
released accidentally before the time is fully noted or agreed.
A good quality alkaline PP3 battery lasts about a week, but
use of the night lights will reduce this life. A lithium type
battery is expensive, but can last even longer. . |

Fit
the battery in the compartment at the rear of the case observing
the correct polarity by proper use of the polarised connector
switch may be fitted in this compartment to switch off the
clock. When first powered up in the marshalling clock mode,
the message 'not / SEt' will flash on the screens. Hold
down the H button and whilst the H button is being held
press the M button. Release the M button. Release the H
button. The clock is in the hours/minutes screen as evidenced
by the existence of the centre colon (double dot). The flashing
pair of digits can be incremented by multiple presses of
the S button, or can be zeroed by the Z button. Pressing
the H button will select either the hours digits flashing
(24 hour format only) or the minutes digits. In the 'setting'
mode, or indeed any mode, the R button will swap screens
so that the four digits showing are either the hours and
minutes (with colon lit) or seconds and hundredths of a
second (with just one decimal point lit). Whilst still in
the setting mode with seconds / hundredths showing we can
either zero the seconds with the Z button as the full minute
comes, or increment full seconds with the S button. When
the time has been fully set, press the H button first, then
whilst holding the H button press the R button. This will
quit the time setting mode, but it is important to note
that there is a reliability feature which prevents the clock
from inadvertently being altered in the field. Once the
'time setting' mode has been exited, it cannot be re-entered
unless the whole clock is powered down for a few seconds
by either disconnecting the battery, or switching the power
on/off switch to the off position if this is fitted.
