TR-SRT-6223+ Separated Type Digital Surface Roughness Tester Meter Diamond Probe Surftest Profilometer Gauge

My company bought one for our machine shop. It was slow. It is so slow on taking measurements, you'll swear it is locked up. One measurement it will say it is 1.5micro-meters, the next measurement on the same spot, 9.8 micro-meters.Slow, inconsistent, useless in small areas both internal and external.Sent it back to Purchasing to return the same day it was received.
