Mode 3:
Push the Mode button twice if you are in Mode 1 - normal pyrometer (only once if
you are in Averaging Mode). A message "
STOPWATCH MODE STOPWATCH MODE STOPWATCH MODE STOPWATCH MODE STOPWATCH MODE " will appear briefly.
This Stopwatch Mode is like having 4 separate watches
to time 4 different cars every lap - at the same time.
The display will appear as follows:
To use the stopwatch function:
Use buttons #1 to 4 (pyrometer Memory) for timing. These correspond to #1 to #4 on the display.
• At the start of the first lap push Memory button # 1
(or 2, 3, or 4 if desired - they are
marked "Time"). If you started with 00.00 00.00 00.00 00.00 00.00 the display will run at this point.
• At the end of the first lap push # 1 again.
The first lap time will be displayed and the watch will begin to internally time the second lap. The display holds
the time. Push #1 only once at this point.
• At the end of the second lap push # 1 again.
Now the time of the second lap will be displayed. You can continue this as long as needed.
• The lap counter will count the laps timed for you automatically.
• You can also watch the time run if you want.
To release the last lap time and see the current time running push the Memory button just to the right of the
timing button you are using - #6 for #1, #7 for #2, etc (they are marked "Run"). The running time will now be
displayed. At the end of that lap push the timing button - #1 to 4 - as usual.
• To stop timing and reset push the timing button & hold for 2 sec.
This will reset the timing to 00.00 00.00 00.00 00.00 00.00 and the lap counter to L0 L0 L0 L0 L0 . It will only affect the one watch #. The others
will continue to run. To reset all 4 push the "Clear Display" button and hold 2 sec.
• To Recall times from memory push Recall Lap Times button and use RF (or
LF) and RR (or LR) to scroll up and down.
The first 70 lap times are automatically stored. To erase all times in Memory push Clear Memory button and
hold 2 sec. When in Timing Mode only times will be erased - not tire temps. When going into Timing Mode a
message comes up reminding you that there are times stored in Memory. You can erase them to start fresh. If
not any new times will be stored after previous ones - up to 70 max.
There is an automatic shutoff to save battery life.
After 10 minutes (2 min. in pyrometer mode) of no use - no buttons pushed - the system will shut itself off. Any
times running will be lost. The system will come up in Normal Pyrometer Mode when turned back on.
