QuadTech / IET 7600 2 MHz LCR meter
RAQU_PL:
There is almost no information about these LCR meter on the forum so i would like to fill that gap.
Meter is too far off on my taste so adjustment will be required...
To cal meter four standards are necessary 24,9Ohm, 374 Ohm, 5.97k, 95.3k with known R, Q on frequencies :1k, 25k, 250khz, 500kHz, 1Mhz.
There is 7000-09 LCR METER CALIBRATION KIT available but considering the price DIY will be best option.
Last cal was in 2002 so it is not very drifty.
If anyone needs more pictures or better quality let me know.
As it is my first post let me know about my mistakes.
RAQU_PL:
more pics.

And more pics.

Surprised to see a pc104 based cpu board in this ....
the other stacked on top of it must some i/o interfaces going into the lcr side
clean layout tests points on the pcb etc ...
nice pick,
would it be better to have it calibrated instead of trying yourself ???
irk seen the cal kit price ridiculous

Yes indeed, it is well built device.
I bought it recently from electro recycling company on local polish auction site .....
Talking about DIY cal i have in mind making standards from VISHAY thin film, low parasitics, stable resistors and sending it to cal.

I very like the method of battery backup of user memory.
Three AAA baterries. No dallas or solderable batteries.
It was built with user and service in mind.
The biggest problem is lack of possibility to stop measurement in progress.
Example: When i do frequency sweep that requires few minutes to be performed and i want to change setting after pressing stop / menu i have to wait for sweep to end.
Or i am an imbecile and can't find another way.
