Identification number that can be assigned to each ChronoSplit, or the bib number of the racer being timed.
(from 0001 to 9999). This allows you to track data from each ChronoSplit using separate ID numbers and to
discern between different data sets from multiple ChronoSplit within a group of athletes. To input a new ID
number activates SET until the leftmost digit begins to flash. Input the new number with START/STOP (+) or
SPLIT/LAP (-). Press SET to confirm selection and proceed to the other numbers as required. This ID
number accompanies data downloaded to PC for easy identification of different data sets.
T E A M
Up to 4 different teams can use these systems within the same immediate area by setting each group of
ChronoSplit to one of four different team groups. The HL 640 – 1 transmitter must also be set to the same
team group number as the ChronoSplit associated with those specific timing points. Activate SET to enter
the change Team number function. Use START/STOP (+) ou SPLIT/LAP (-) to select and confirm with SET.
P C
Allows for memory download of all stored timing session data to a PC using the appropriate RF interface and
a USB port on the PC. Place the ChronoSplit within 2 meters / 2 yards of the USB interface kit connected to
your PC. (see "interface" HL 640 - 2). It takes about 10 seconds to download 50 stored times.
Remarks
In AUTO SPLIT mode, each radio signal received from the transmitter programmed on CHANNEL 1
(START) shows 4 dashed ( - - - - ) on the LCD display (control of radio signal reception).
If the ChronoSplit does not receive any transmitted signals for more than 1 hour it will automatically enter
TIME mode to conserve battery power.
The maximum elapse time recordable in any one timing session is 15h 59'59''999
.
There is a rapid access feature to be able to quickly see the times from the last timing session. Activate
MODE and press START/STOP. All times from the last recorded session are now visible. This technique can
also momentarily black all incoming radio timing signals in AUTO SPLIT or AUTO LAP while you review the
last timing session data on the LCD screen. This feature is particularly useful as athletes gather again at the
start after their last timed run. ATTENTION: remember to return to AUTO SPLIT or AUTO LAP mode prior to
the next timed run.
Warning : a transmitter can’t transmit timing impulses closer than 270ms (i.e. speed measurement – distance
between 2 photocells must be min. 10 meters at 100km/h).
CAUTION !
NEVER
press START/STOP, SPLIT/LAP and MODE buttons simultaneously!
Doing so will require you to remove and replace the battery in order to reactivate
the ChronoSplit!
