Fluidmaster; can you adjust the short flush?

[amfisted]

Is it possible to adjust the length of the short flush on a button cable Fluidmaster fill and flush valve? I think it must be, because Welsh Water removed our internal water meter the other day ( replacing it with a "smart" water meter outside) and the short flush now shuts off almost instantaneously. Presumably they adjust it as a water-saving measure without telling the customer, but to my mind its now far too short. If there's no suitable adjustment then we'll just have to flush twice where necessary or use the longer flush, which rather defeats the object of their fiddling with it in the first place.

This is the valve: https://www.screwfix.com/p/fluidmas...-2-button-cable-dual-flush-bottom-inlet/58353

Thanks both. It’s so simple that I feel like a bit of a fool for asking. But if you don’t ask then you might never know, and having fitted this flush valve about 18 months ago the instructions are long gone.
