DE-5000 including optional accessoires and standard suitcase

IET labs is a company that makes the best LCR meters in the world. They however are by many people known under an other name, Genrad or General Radio. IET was the bridge department of GR. They still produce several products from that periode, like the GR-1620. http://www.ietlabs.com/lcr-meter/de5000-lcr-meter.html

The DE-5000 is not made in the USA. It is based on the cirrus chipset (according to people on EEV blog, I have not opened mine, I do not like to open a precision instrument if not neccessary) It is produced in Taiwan under supervision of IET. That keeps it afforable.

Battery compartiment detail

Battery compartiment detail

Nice detail, You can not insert the 9V battery the wrong way, and the battery included is not just a chinese crappy thing but a duracel.

But important is, how accurate does it perform. I have measured most of my standard capacitors, resistors and inductors and it is very good. Only thing that is not accurate is D at capacitor values under 40pF but above that it is very good.

Test

Test

As you can see the capacitance is only 10fF off. That is between -0.039 and -0.087% (because it can be 10.1549 and the display 10.15) Not bad at all.

Some other values:
40.1370pF and D=0.004928 (GR1620)gave 40.05pF and D=0.005
321.4997pF styroflex D=0.000108 (GR1620) gave 321.5pF D= 0.000
21,38uF ceramic D=0.016 (on GR1608) gave 21.38 uF D= 0.009

Some inductors. Very hard because current influenses the result.
Aircoil, 229.9 nH, 62mOhm at 10KHz gave 0.232 uH 40mOhm
Aircoil 131.3 nH, 11,7mOhm,Q=1.418 at 10KHz gave 0.130uH Q=1.85

A 20K resistance standard gave 20.00K, have not tested lower values yet.
