Hi Helpers, I am working on vibration service on gas turbine and facing a problem in collecting vibration data. My Instrument is : DAIU and ADREE, Optical Sensor(Monarch ROS)as a tachometer. The runing speed is 3000 rpm. The first one occured in startup, the optical sensor is triggering the DAIU to start sampling but on 1500 rpm not from 100 rpm which made me to lose first resonance and of course it is occured the same in shutdown also, the optical led showed light on 100 rpm but without appearing in The DAIU...Pleas have any one faced such problem with opticals tacho taking inmind that I used it before and the DAIU detected the low speed pulses. Thanks in advance. Jone
