content: heyso today I've worked with the fluke 5700 ! what a lovely beast !so I've tweaked my fluke 87V ( yup , calibration is only referencing ) and after 36 steps and perhaps 20~30 mins I've finished , before that tweaking he drifted by constant of perhaps 10 counts - BUT now ! ~ he's 1 count out ! that's amazing ! ( note , 1 count out versos the freaking beast)I had one 440mA fuse blown there , so they replace it , but obviously I need to pay right ? well nope , the tweaking and the fuse was for free ! ( I calibrated few other meters hence I did some job so he told me " you have earned your bread " LOL )so I calibrated some fluke 287 179 and few cheapies , and that the best job ever !I am only 17 but they call me geniusthey have some 1G decade boxes ( 5KV ) and some AWSOME stuff ! scope calibrators and all sort of things , I am so happyso any body there where russian . but they are great people . very nice guys indeed ,anyhow - that might me my first proffesional job

content: for that fluke 287, it has option to skip the cal point or it will rewrite everytime the cal constant for that point? dont remember exactly how its working, ive read their cal manual a year ago for my meter

content: Good for you!I'm glad you're so excited. Allow me to give you some advice though. Don't talk much. Listen much, talk little. ASK before doing anything you aren't absolutely sure. Think 2 times , do 1. Good luck! :-)

I believe he is absolutely right.Quotes I remember (but "from whom" I have forgot):"First seek to understand, then seek to be understood.""You don't learn anything by talking, you learn by listening."I distilled that down further for my then toddler, she is now getting ready for high school, but she still remembers:"Don't talk when you are ready to talk, talk when others are ready to listen."Rick

content: heythank you guys !yup - the part of listening is very clear to methe funny thing is that they have got some little "card" power supply ( SMPS) for some counter ( perhaps some agilent or so ) and the SMPS doesn't work at all , they told me that one like this cost 1.7K$ , so I told them to give me 20Mhz Diff probe and some other tools and I'll try and repair that one , I believe I'll manage to do so because that SMPS is very simplistic , but nonetheless ,they also have got some Eloads for repair and some DECADE resistance ( IET ones ) boxes , and they told me to try and repair some industrial oven PID controller , I am going to open thread on one of those , due to the complexity and the sort of field I am not yet good atCheers !

content: I've worked today for 6 Hrs and that was fun !the boss gave me few K type thermocouple for free !he gave me Pomona's one , one surface ( that is actually thermistor up to 150C ) . one liquid thermo couple and one aligator clamp .plus he gave me that thermocouple adaptor to Double banana plugworking with Darton calibrator and the fluke 5700 is awsome !Cheers

content: heythe temperature probe is thermistor - does someone have scematic for the circuit in order to do 0.1C/0.1mV ?the Boss told me that whatever gear i need from the lab(s) I can borrow for mt projectsthank you
