ISS High Beta Angle means the next few orbits will be continuous sunlight.

Starting to look a little chunky at the hatch end.

GO for inflation.

Opening the valve 5 sec at a time. Starting to lengthen.

Certainly looking a little more chubby.

Whoops. Jeff reports hearing a noise on the other side of the hatch "something is loose".

Seem to be taking it a little slower after the reported noise!

Not really too obvious yet.

Slightly high on pressure curve. Waiting for it to settle.

When you say slightly high, as in too much air went in? Would it settle or just stay at that higher pressure?

It could expand, and thus lower the pressure.

We are talking about very low pressure at the moment, they are wanting to avoid a build up of pressure as that could result in a sudden large increase in expansion.

One more "generous" second of valve opening. No noises this time. 19.5 psi.

Pressure at 19.5. What units are those? kPa?

Psi!? That's more than atmospheric.

From the multimeter, it looks like mA. Conversion from a pressure sensor current reading to actual pressure is left up to a conversion table and calibration curve, which is specific to sensor model and potentially serial number.

looks like very serious discussions on the pressure curve.

"We're above the safe inflation curve" - which is why they are going slowly. All a learning curve.
