Page 4: Functional Description
Elma 6400 3. Functional Description 3-1 Introduction The LCR meter could measure Inductance/Capacitance/Resistance with secondary parameters including dissipation factor(D), quality factor(Q), phase angle(θ), equivalent series/parallel resistance(ESR or Rp). The meter is fully auto ranging operation for AC impedance & DC resistance measurement. It means the user could measure the L/C/R components directly at AUTOLCR smart mode without changing the function key. -

Elma 6400 5. Powering Instrument Before beginning to operate the instrument, a power source is necessary for it to turn on. Installing Battery 5-1 Installing Battery The LCR meter use battery to provide power to the instrument so that it can be portable. - Page 7 Elma 6400 • Auto power off In order to extend the battery life, except of using external power supply, APO feature will be helpful. It can be enabled or disabled APO function by press the APO button and the LCD will show whether the function is enable or not. When all...
- Page 8 Elma 6400 • Series/Parallel mode select The LCR meter offers the option to select between parallel or series measurement mode. Depending on which mode is selected, the method to measure the component will be different. Additionally, one measurement mode may provide better accuracies over the other measurement mode depending on the type of component and the value of the component to be tested.

This section provides some recommendations and suggestions to consider.
- Page 15 Elma 6400 Inductance Typically,a 1 kHz test frequency is used to measure inductors that are used in audio and RF circuits.This is because these components operate at higher frequencies and require that they be measured at higher frequencies such as 1 kHz or 10 kHz.
- Page 16 Elma 6400 Inductance Some inductors are intended to operate at a certain DC bias to achieve a certain inductance value.However,the LCR meters cannot produce such biasing scheme and external biasing should not be attempted because external power would be applied to the instrument and cause serious damage to the meter. Therefore, in some cases, measured inductance reading may not agree with manufacturer’s...
