Time1
The times are only measured if the switch or control switch, assigned
in the line "Lap time/Time tab." of the "Phase timer" menu, is
"closed”. The frequency of the switch actuation is displayed in the
basic display. This counter will be highlighted as soon as the switch
for the "Time1" timer is "open", the timer is hold (stopped).
In the stopped state, the recorded switching times can be succes-
sively read out with the selection keys.
Time2
"Time2" stores both the "Off" and "On" times of the associated
switch. Each time the switch is operated, the time count starts again
and the counter is incremented by "1". The timer can be stopped at
any time via the central ESC key on the left touch panel without actu-
ating the switch. Running the switch while the stopped timer is
stopped increases the counter by 1 and restarts the "Time2" timer.
In the stopped state, the recorded data of the "Time2" timer can be
successively read out with the selection keys.
