Guys and girls using the Supco VG64 vacuum gauge. I note that from the box it gives a fluctuating reading. Not constant and it can jump as much as 300-500 microns up and down. I know it may be due to contaminants and air moving over the sensor but I’m not used to seeing this with other gauges such as the testo, at least not as fast and not by as much. Is it normal for this meter ? Any other tips when using it. I am currently evacuating a moisture contaminated system with it and it’s going crazy but it’s only the second or third time in use and it’s done it even on clean systems.
