Does it need calibrating? And if it does, how often?
Thanks. Nice video.

The prongs on the SP620 is alot narrower/smaller than typical manometers. What type hose /size do you use? Or do you need a hose adapter in which a standard hose fits the Meter nipple and a smaller hose fits into the SP620.

What's the permissible drop with a digital monometer?

Hi John, At 3.07 in the video it states an 8 mBar permissible drop (with no smell of gas) on this E6 (Smart) Meter. Thanks for watching.

@Peter Philpott think he's referring to perceptible movement in the gauge where it has to be noted. any movement more than 0.2mb
