I would like to ask my fellow friends: what is the suc.press., that is, the suction pressure?

Background explanation: The device is a Roots blower, and the photo shows its nameplate. The altitude of the location where it is used is 1200 m, with an atmospheric pressure of 87–88 kPa. The parameter on the nameplate, SUC.PRESS. ATM, refers to the suction pressure. Does ATM denote standard physical atmospheric pressure or ambient atmospheric pressure?

In engineering fluid mechanics, which specific one is it referring to? Those who know about this, please join in. Thank you
