On pump readout in back of machine, we have this inf, our processor was
purchased in 1984 and still going strong!!   

Red numbers = vacuum goes to 50 - 60 cm Hg.  

Black numbers = pressure,  should be 0.25 - 0.3, below 0.2 relief valve may
need adjustment. 

For delicate tissues, we turn the pressure/vacuum off, or program it as

Sakura has a way to do a pressure/vacuum check by keying in certain codes,
a phone call to their tech services would do this.
