Just a quick one here, Was gas rating a boiler the other day , the tenant had a E6 token meter.
Opened the hot tap, went to the meter , pressed the B button which shown me the meter index, took the reading and start the 2min test. Ten seconds in and the meter index dissapered, Kept having to press the B button to get the index update.
Is there an easier way of doing this or is that it cos if it is then that is not anoying at all.
 
when you first press the button is when you start your two minutes when the two min are up press again dont worry how long it takes to appear the index is taken at the time you press the button
 
there is a technical bulletin about this issue if anybody want to go check it out. TB 112 i think
