Can you please provide the Model no of FLUKE meter to be used....? thanks. RE: thread380-361460 Hi LaserNinja, LASERNINJA (Mechanical) 19 Apr 17 15:27 I think it's a 83-lll with a banana to BNC adaptor. It doesn't really matter. As long as it is of decent quality. RE: thread380-361460 Hi LaserNinja, PGP_1967 (Industrial) (OP) 20 Apr 17 04:12 Thanks LaserNinja, I am in a situation on Muratec Centrum C3000 ( Fanuc C2000 B ) Hybrid machine. The Laser resonator was kept Idle for last 8 months or so.....just because client did not know how to operate. when I checked ....and started the resonator ....came up to 1200 W ...throwing the " Mirror Cleaning " alarm. Did the resonator maintenance ....found the Rear Mirror , Output Coupler & one Folding Mirror....color distortion..needs replacement. however tried to clean as far as possible and started the resonator....purging , leak test , aging done....adjusted the peak power to obtain 1400 W ....still the " Mirror Cleaning" alarm exists.....obvious...! The main problem is....when Laser Sequence 30 (LSTR) is Ready.....the Laser power is 150~200.....and the tubes are also ignited ..say about 15 to 20% . To my knowledge Laser power at LSTR should be "0"....STAND BY ......your comment. now the problem is ....just because the laser power is 150~200.....when i open the shutter the beam is OUT....this is dangerous. At Sequence the DGN is as follows 904 GAS PRES. CONTROL -- 2069 905 LASER TUBE PRES. -- 690 906 LASER POWER -- 155 907 TRACE DATA -- -7744 908 LASER SEQUENCE -- 30 So...this is the issue....what exactly is causing the power not to become ZERO. how to overcome this situation.... your expert guidance is valuable and awaited. thanks. RE: thread380-361460 Hi LaserNinja, LASERNINJA (Mechanical) 20 Apr 17 13:24 I haven't had any coffee yet so forgive me. I will try to help out more later. It really sounds like your gas bottle went bad. Is it possible it get another, purge the heck out of the machine and try it again? RE: thread380-361460 Hi LaserNinja, RPosty (Mechanical) 27 Apr 17 19:08 Your Base Discharge is too high, if you have the Fanuc manual adjustment procedure is in there. Our Manual is B-70125EN/03 Section 9. Basically after you setup the parameters you adjust VR11 with 0 power commanded until discharge stops then back off until it just blinks on. You may trip breakers if you are too aggressive with adjustments. We just decommissioned a C2000 so if you ever need matched RF and DC units, hit me up, I think I could get owner to part with them much cheaper than fanuc or PLCCenter. i.fix.stuff at live. I don't make commision, just tired of the laser just taking up space.

Been a while since I worked on this machine, but pretty sure this is correct. I used to have to spend a couple of hours to tune the RF/DC units to stop tripping breakers. Sometimes they are just bad. If adjusted wrong they can trip.
