水草情迷

Hi all,
Today I bought a CO2 bottle with 2 head meter and electric valve. The boss show me there is 50-60 bar shown in the left meter and 2-3 bar shown in the right (output) meter when he turn on the CO2 bottle (at that time, he didn't show me the electric valve cos we trade in MTR station). And then he turn off the CO2 bottle but the output meter stills shown about 2-3 bar.
When I arrived home, I found the output pressure raise. It shown about 10 bar in the output meter. Then I switch on the valve and turn on the CO2 bottle. The CO2 came out but after a minute later, there is no CO2 came out. And then I found that there is zero reading shown in the left and right meter.
Is there something wrong for the CO2 bottle or meter?
I'm looking for your reply

I think the CO2 cylinder is ok la. just turn on the main valve , then turn on electric valve after that , thurn on the small valve slower to adjust the output.

if still have problem, exchange with the salesman.
