ET4410 Desktop LCR Meter Continuously Adjustable Capacitance inductance Test Instrument Grey

For an instrument of this cost, I expect a well-written manual. This doesn't have it. While I can tolerate poor manuals, if I can figure out the relatively complex instrument, I have even less of a stomach for mis-prints and grammar mistakes on the front panel.I am referring to the "frequency" button which is printed as "freg", with a gee, not a q. Ouch. That single mistake makes the product difficult to keep. You can see the mis-print even in the Amazon product photos. eff are eee GEE. Yikes.The first functional problem was measuring a capacitor. It worked OK but was off by about 0.75 picofarads whilst measuring a 1.5 pf capacitor, even though the stated accuracy is a fraction of a percent. I figured out how to do a calibration, and then it worked better, but I was starting to lose functional trust in the unit.So I tried a 100 nano-henry inductor, that's a standard value for a project that I'm working on. The unit couldn't determine any inductance on the part under test. I thought that was within the range of the unit, checking the manual and the website (see the image I took). Should have worked.So I tried a second inductor.... no joy, didn't work either. Am I doing something wrong? It was seeing my inductors as a dead short, occasionally a little but of sputtering inductivity on the meter.At that point, the irritation of a bad manual and a mis-printed button on the unit came over me. This one's going back, and I'm ordering another LCR tester.

Meter more a engineering tool not for repair
