Question: Absolute pressure, gauge pressure

I have a pressure transmitter used for measuring absolute pressure; its measurement range is from -1 to +1 kg/cm2A. So, when the gauge is placed under atmospheric pressure, what should be the displayed value in kg/cm2A? Is the correct value 1 kg/cm2 A, or 0 kg/cm2A?
It should be 1 kg/cm2 A, right?
I think it’s also 1 kg/cm2 A; it will become clear once you convert it using a unit conversion tool.
0 kg/cm2, idiot FUCK
The absolute pressure of air is 1 kilogram of pressure; if the absolute pressure of the atmosphere were 0, then our Earth would become a vacuum planet. :)
When the gauge is at atmospheric pressure, its reading should be 0 kg/cm2.
