Timing Modes
We use two different timing modes: difference timing and absolute timing. You must select the
timing mode before you start a race:
Select timing: ABSOLUTE F1
select with <F1>
DIFFERENCE< F2
select with <F2>
Continue: ENTER
Absolute:
Time starts form 0:00.00
The run time (and intermediate times) are stored for each competitor.
This mode should be used for races with mass start.
Advantage:
For each competitor only one memory place during the first heat (if you have no
intermediate times)
Disadvantage:
If you do not have a mass start, it will be impossible to make time corrections
Selection:
Press <F1> and <ENTER>
Difference:
The time of day is stored for each start- and finish impulse. Therefore you have to input the time of
day first. From the difference between finish time and start time it calculates the run time.
This mode should be used for single start and group start races.
Advantage:
You can correct times.
Disadvantage:
For each competitor it needs at least three memory places (start-, finish-, run
time)
Selection:
Press <F2 > and <ENTER>

Test-Function - Checking the TdC 8000
When you press <TEST> the Info-Display (6) shows the following:
C0 = 4.9V battery = 7.3V
C3 = 4.9V photocell = 4.9V
C6 = 4.9V extender = 0.00A
# # # # # # # # # #
c0 c1 c2 c3 c4 c5 c6 c7 c8 c9
The Test-Function shows the condition of the device. The condition of all ten channels are moni-
tored (line 4). If one channel blinks, it means that it has a short-circuit. For channel c0, c3 and c6 the
voltage is shown.
In addition it shows the voltage of the NiCad battery, the photocell, and the current for the extender.
Channel c0, c3, and c6 should normally have about 5 V (open). When an impulse is reached the
voltage must go down to 0 V.
