Beckman Coulter z1 Abnormal aperture flow rate
Hi everyone.
Dealing with: '' Abnormal aperture flow rate'' error message. nothing seems to be clogged. Meetering pump and control valve pass all the tests in the user testing menu.
Look like the pump is struggling to build a sufficient vaccum.
The instrument start the count and then: ''Abnormal aperture flow rate''
error message
Could it be that diaphragm inside the pump?
Beckman Coulter Part number ?
Thanks!
