Reset stopwatch hands on can1011 - Tag Heuer Aquaracer Quartz Chronograph CAF1112.BA0803

Unscrew the crown, start the stop watch on the time signal. Stop the second hand at 12 o'clock and reset the time (taking out the back lash on the minute hand) Start the watch as the stop watch second hand hits 12. Screw down the crown. Done.

As jimmyguru said.
1. Pull the crown to the second position (all the way out)
2. Push and hold the reset button and allow the chronograph hand to rotate near the 12 o'clock position.
3. Release the reset button.
4. Repeatedly push and release the reset button to find tune the hand position until it is right at 12 o'clock.
5. Push the crown back in.

When you reset the big seconds hand to zero, the hour and the minute hand are not engaged in this function, so, there is no fault with the watch movement.
Do as follows:
1) pull out crown and set the hour and minute hands at 6 o'clock (they must be lined perfectly in opposite directions)
2) push the crown in half way back (not completely)
3) push and hold the button at 2 o'clock (set the big seconds hand to zero) and release it when done
4) when big seconds hand is zeroed push the crown back in
5) pull the crown out again and set desired time
6) push the crown back in.
If all actions described do not work, you will have to visit your nearest watch repair shop and ask to refit chronograph hand as in this case it is out of balance (not pointed at exact mark).

Rate me, please.

Try this: pull out crown to the first click, then push and hold button at 2 o'clock. When the hand is adjusted to the desired time, push the crown back in.
If thi do not work, do the same using the button at 4 o'clock.

Rate me, please.

Your watch has quartz movement and stopwatch adjustment by one step (one full second) only. That means you will not be able to adjust stopwatch hand by using pushers on your watch as each push of the pusher will advance stopwatch hand for the full second, not the fifth or the tenth of the second, and the hand will stay slightly off anyway.
This happenened because the IC (integrated circuit) in your watch miscalculated the teeth count on chronograph wheel and stopped one or two teeth past or under the zero point. It doesn't happen very often, but in your case it did and the only solution is to find your nearest watch repair shop and ask for resetting stopwatch hand to zero.
This procedure needs partial disassembling of the watch and quite a great skill as the stopwatch hand must be removed and then refitted with great accuracy. All this needs to be done by very specialized tools as well.
I think this is the only solution of your problem unless you can live with that and just leave it as it is.
Do not forget to rate, please.

Pull crown out to position 2 [in between unscrewed (1) and pulled all the way out (3)].  Tap Button B (bottom) to reset by step back to zero.
Incidentally, Button A works Hours register in same manner for position 2.  You can similarly reset second and 1/10th with Buttons A and B, respectively, while in position 3.  Cheers! 

pull the crown on first click and push the upper button until it reaches to your desired position.

Pull the crown to first position (where you set the date) then adjust the dials with buttons.

The larger second hand on the Pulsar PF8036 is part of the stopwatch feature. The upper button starts/stops the stopwatch feature, and the lower button operates the lap/reset function. Why they made the larger hand work only with the stopwatch instead of the smaller hand to the left is beyond me, but that's how it is designed.
