LCR meter model 380193

[hasan hadi]

i having device LCR meter model 380193 but i founding some proplem
1- how working this device
2- this device measuring impeadance(Z) or not measuring
3-when using key PAL\SER and key FREQ 120HZ and 1KHZ
4- When key FREQ 120HZ the reading is diffreance when using key 1KHZ
5-at working device display all symbols in the screen this symbols all active or some symbols is active example symbols Z is apear in screen but not founding in keys
6- how measuring off angle
please i wanted answer of this equation

Quote from Extech site"Extech's Model 380193 LCR meter. This meter will
accurately measure capacitors, inductors and resistors using the test frequencies of
120Hz and 1 kHz. The dual display will simultaneously display the associated quality
factor, dissipation or resistance value using a series or parallel equivalent circuit.")

Thankyou master jazz p bass
1-this mean device LCR meter model 380193 cannot measuring impeadance(Z)
but the symbols Z and angle is founding in the screen why not active?
2-how using key PAL\SER and key FREQ 120HZ and 1KHZ
for accuracy for reading
3-When key FREQ 120HZ the reading is diffreance when using key 1KHZ why

Please attempt to contact the manufacturer.

The Inductance of a coil IS frequency dependent.

EDIT: Impedance not inductance of coil

I do not understand how you draw that conclusion from the contents of the article you linked to.

[Jazz P Bass]

Sorry for the misinformation.
The link was a general inductor link.
Impedance of a coil will increase with frequency.
That is why there are two frequencies on the Extech.
(why only two, this I do not know.)

It looks as if the meter does NOT display magnitude and angle. You'll have to calculate it yourself, but this is easy.

Inductance is not supposed to vary with frequency. An ideal inductor would give you the same reading on the meter at 120Hz as at 1kHz.

But in practice it does vary, because of eddy currents, core losses etc. The two measuring frequencies are provided to let you get an idea of the non-ideal behaviour of the coil.

how using this device to calculate magnitude off impeadance and angle can be example
and when using key 120HZ and 1KHZ i need example
and when using key SER and PAL i need example
