Wszystkie te tansze sa na uladzie cyrustek ES51920S i ES51919Q. DE5000 ma pewna ciekawostke. Blaszki nie sa caloscia i podpiecie jest do nich tak z ukladu ze wkladajac pomiedzy nie 2 warstwowy PCB mamy wyjscie 4 przewodowe, w CEM niestety jest to polaczone na PCB. Jest to niby i zaleta i wada... jak zaczna sie problemy ze stykiem na nich bedzie trzeba zapewne doginac... Do tego troche ladniej jest poprowadzona masa (pomiedzy ES519990 - a ukladem obslugujacym LCD).

Chapter 1: Introduction
1.1. Overview
The DE-500 is a portable, high-performance LCR meter that is
full-featured yet cost effective. It measures in true 4-wire Kelvin
mode and rivals the capabilities and options of many of its bench
counterparts.
It measures:
Ls/Lp
-- Series and parallel inductance
Cs/Cp
-- Series and parallel capacitance
Rs/Rp
-- Series and parallel resistance (ac)
Rdc/Rp -- Series and parallel resistance (dc)
ESR/Rp -- Series and parallel equivalent resistance
D
-- Dissipation factor
Q
-- Quality factor
Θ
-- Phase angle
This LCR meter can transfer data to a PC via a standard, fully
isolated, optical IR-USB interface.
It also features a Sorting
mode, allowing users to quickly sort components.
DE-5000 has automatic LCR selection. This allows the user to
measure the L/C/R components in Auto LCR mode without
having to select the type of measurement.
-1-
To accommodate various test requirements, the DE-5000 offers
selectable test frequencies: 100 Hz / 120 Hz / 1 kHz / 10 kHz /
100 kHz.
The unit is powered by a standard 9V battery.
For additional
convenience, it may also use an optional ac adapter
(DE-5000-AC).
To transfer data to a PC, the unit comes with a built-in IR
interface.
IET offers an optional Data Transfer Kit
(DE-5000-DTK). This kit includes: IR-USB interface adapter,
a USB cable, and a CD with software for the PC.
1.2. Introduction to measuring principles
1.2.1. What is impedance
Impedance (Z) consists of resistance (real part) and reactance
(imaginary part). Series impedance (Zs) can be defined as a
combination of series resistance (Rs) and series reactance (Xs). It
can be represented mathematically as magnitude |Z|=√(Rs2+Xs2)
at a phase angle Θ.
-2-
Zs = Rs + jXs or |Zs|∠Θ
Rs = |Zs| cosΘ
Xs = |Zs| sinΘ
Xs/Rs = tanΘ
Θ = tan-1(Xs/Rs)
There are two types of reactance. One is inductive reactance –
XL, and the other is capacitive reactance – XC.
If Θ & gt; 0, the reactance is inductive. If Θ & lt; 0, the reactance is
capacitive.
The inductive and capacitive reactances (XL and XC) can be
defined as:
XL = 2πƒL
XC =1÷(2πƒC)
Where:
L = Inductance
C = Capacitance
ƒ= signal frequency)
-3-
1.2.2. Measuring impedance
Impedance can be measured in series or in parallel. In parallel
mode, impedance can be represented as reciprocal of admittance
(Y). The admittance can be defined as Y = G + jB, where:
G = Conductance
B = Susceptance
Series impedance
Parallel admittance
Y = 1/Z = 1/Rp + 1/jXp = G+jB
Rs = Series resistance
Xs = Series reactance
Cs = Series capacitance
Ls = Series Inductance
Rp = Parallel resistance
Xp = Parallel reactance
Cp = Parallel capacitance
Lp = Parallel inductance
To understand the ratio of resistance and reactance, it is
important to consider two factors: quality factor (Q) and
dissipation factor (D).
Usually Q is used when measuring
inductance and D is used when measuring capacitance. D is
defined as the reciprocal of Q.
Q = 1/D = tanΘ
Q = Xs/Rs = 2πf Ls/Rs = ½πf CsRs
Q = B/G = Rp/|Xp| = Rp/2πf Lp = 2πf CpRp
-4-
Both Rs and Rp are part of the equivalent circuit of capacitors
and inductors. When measuring capacitance and inductance, it
is best to use the settings as shown in the table below.

Chapter 2: Operation
2.1. How to obtain optimum precision
To access optimum precision for all L, C, and R measurements,
especially at the highest and the lowest ranges, zero the instrument
before use (pages 16-18).
To secure the specified accuracy, connect the device under test
(DUT) to the measuring socket, or use either TL-21 (standard
accessory) or TL-22 (optional accessory).
If you are using test leads other than the ones specified above, use
4-wire leads and avoid using long lead wires to reduce measurement
errors.
2.2. Default settings
When the power is turned on, the monitor displays all symbols for 2
seconds as shown below.
- 12 -
When the meter is powered by the battery, it is in an
automatic-power-off mode. APO is shown on the display.
In this
mode, if the unit is inactive for 5 minutes, it shuts itself off.
First,
the buzzer beeps three times to remind the user, then OFF is
displayed on the monitor as shown below while the unit powers
down.
Note that when the unit is powered via an ac adapter, the
automatic-power-off mode is inactive.
The default settings for the meter set LCR in auto mode and test
frequency at 1 kHz.
The battery condition is continuously displayed.
the battery capacity is full.
means that
means that battery power is low
and the battery needs to be replaced.
The LCR meter uses beeps to indicate whether a particular key has a
function in a given mode. If a functional key is pressed, there is a
single beep.
If a non-functional key is pressed, there is a dual beep.
- 13 -
2.3. Zeroing the meter
Zeroing the instrument gets better accuracy for impedance
measurements. The purpose of this procedure is to reduce the
parasitic effect of the test fixture.
ZM is the total impedance measured on the device under test (DUT)
by a test fixture which has some parasitic impedance.
ZM = (Rs + jωLs) + ((Go+jωCo)-1 || ZDUT)
ZDUT is the target impedance user wants to measure. It is necessary
to use the zeroing process to cancel the effect of Rs+jωLs and
Go+jωCo.

Adjustment to accuracy (Z) based on dissipation (D) reading:
D & gt; 0.1: Z * √(1+D2)
In capacitance mode, D ≤ 0.1: ZC = 1÷(2πƒC)
In inductance mode, D ≤ 0.1: ZL = 2πƒL
Secondary Parameters Accuracy:
AZ = impedance (Z) accuracy
Definition: Q = 1/D & Rp = ESR * (1+1/D2)
D value accuracy: DZ = ± AZ *(1+D)
ESR accuracy: RZ= ± ZM * AZ ( )
ie., ZM = impedance calculated by 1÷(2πƒC) or 2πƒL
Phase angle Θ accuracy: ΘZ= ±(180/π)*AZ (deg)
