Help needed - counter circuit

[circuitfish]

I've built the circuit below. Unfortunatly, the fuse on my voltmeter has been blown by a numpty (aka me). I was wondering if anyone could tell me how v out would change over 20 seconds or so.

Any help would be much appreciated,
Thanks.

As its 16 bit divide, the counter would rollover to a count of 4, after 20sec, so the Vout = [4/15] * Vref.

thats about 0.333 *4 = 1.33V

hi,
Look at this sim of your circuit, you can see that bit Q3 is high after 20secs

Have you tried to replace the blown fuse in your meter.??

Thanks, I will be replacing the fuse, yes, but I'm on a bit of a tight schedule.
