I asked this question few weeks ago but still confused.
Im quoting some of this from a book.
Test for regulator working pressure at meter 'Turn on ONE appliance at full rate(lets say cooker)' should read 21mb+/- 2mb. (For arguments sake say pressure was 21mb). It then says with ALL APPLIANCES RUNNING there should be no more than 1 mb drop between meter outlet and appliance. Therefore inlet to all appliances should be no less than 20mb. But would the regulator maintain this pressure of 21mb with all appliances running.
To sum up if 21mb at meter with cooker on it should it be 21mb with all apps running?
When I have tried this the regulator as dropped to 19mb with everything running. Can regulators compensate 100%. Is this where the tolerence comes in (21mb+/-2mb) with one app on and then you allow for 1mb drop across system or maybe 21mb and allowed to drop to 19mb with all apps on. Im a trainee and nobody can seem to find my answer.
Thank you very much everybody.
