2. SPECIFICATION

This LCR meter offers a wide range of functions at a low price. The LCR
meter can measure capacitance, resistance, and inductance among
other things. In addition, it can automatically recognize components, for
example, it can distinguish between different types of transistors, such as
NPN or PNP transistors. The device is particularly easy to operate, as all
measurements are started at the touch of a single button.
Thanks to the integrated about 300 mAh battery, measurements can also
be carried out on the road. The battery is charged with the help of a 5V
power supply unit (available separately) and the enclosed micro-USB
cable. In addition, this measuring device can decode infrared signals and
show them as a waveform on the display.

4. INITIAL OPERATION

When you start the measuring device for the first time, you should first
perform a self-test of the device. For this purpose, you must short-circuit
the slots 1, 2 and 3. You do this as follows:

Now press Start to perform the self-test. You will be asked by the device
at approx. 22% to remove the component so that the self-test can be
completed successfully. Now you can start measuring your components.
You start the measuring process with the Start button.

A 3.7 V battery with about 300 mAh is built into the multifunction tester.
You can charge it with microUSB and a 5 V power supply. The LED shows
the
status of the battery. That means it shines red when the battery is
charging and green when the battery is fully charged.

The battery of this measuring device is also measured during each


component measurement. Therefore, the residual voltage of the battery
is also displayed during each measurement. This residual voltage is
displayed with Vbat = …V.

The device will also tell you when the battery needs to be charged again.

This device will automatically turn off after 20 seconds of inactivity. You
can also turn it off manually, by pressing and holding the Start button.
Pressing and holding the Start button for 3 seconds will put the device

5. MEASURING COMPONENTS

This measuring instrument can detect and measure diodes, Z-diodes,


double diodes, resistors, capacitors, inductors, thyristors, triacs, field
effect transistors, bipolar transistors, and batteries. In the following, you
will find information on how to measure a component and which values
can be measured for the specific components.

To measure a component you can use slots 1-3. Just make sure that you
do not connect two cables to the same channel, i.e. the same digit. So
you have to select any slot at 1, 2, and 3 for three connections.
To measure the breakdown voltage, use channels K and A. Connect the
positive pin to K and the negative pin to A. You will find further
information under Z-Diode.

You can either plug the component directly into the terminals of the
device or use the cable clamps provided.

When you have connected your component, press down the lever and
start the measurement with the start button.

If no component or a defective component has been connected, or the


component has been connected incorrectly, the following message is
displayed on the screen.

Diode
Uf - forward voltage
C - capacity
Ir - leakage current

Z-Diode
Uz - reverse breakdown voltage / Z-voltage
Here the breakdown voltage of a component is
measured, so here the positive line must be connected to
K and the negative line to A. Up to 30 V can be measured
in the reverse voltage.

Double diode
Uf - forward voltage

Resistor
Here the resistance in Ω is displayed.

Capacitor
The capacity is displayed here.
Vloss - Loss factor
ESR - equivalent series resistance

Attention!
The capacitors must always be discharged before you
can test them, otherwise the multifunction tester
may be damaged!

Inductor
The inductance is displayed here.
R - resistance

Thyristor

Triac
Uf - forward voltage

Cg - gate capacity
Rds - drain source resistance
Uf - forward voltage
@Vg - gate voltage
Here the multifunction tester can distinguish between
N-E-MOS, P-E-MOS, N-MOS, P-MOS, N-JFET, P-JFET,
N-IGBT and P-IGBT.

Bipolar transistor

with diode.

Batteries
The battery voltage is displayed here.

Attention! The battery must have less than 4.5 V,


otherwise the multifunction tester may be damaged!

Infrared-Decoder
The infrared decoder is located next to the start button
and does not need to be activated separately. You can
simply e.g. activate your infrared remote control in front
of the device, which decodes it immediately. You can
then see the UserCode and the DataCode in hexadecimal
format on the screen. The UserCode is the specific code
of the remote control you are using and the DataCode is
the code of the button you pressed.
The dot at the top right corner indicates whether it has received infrared data from a remote control.
Therefore, red represents that infrared data is being received, blue represents a decoding success.
However, only the NEC protocol (which is used by many manufacturers) can be decoded. If you
transmit an infrared signal that does not correspond to this protocol, only the red dot in the upper
right corner of the display lights up to indicate that an infrared signal has been received. This red dot
would light up blue for an infrared signal corresponding to the NEC protocol and would be decoded.

6. PROBLEM CASES

With the measurement results, you should never forget that the circuit of
the transistor tester is designed for small-signal components. As a rule,
the maximum measuring current is about 6mA. With power semiconduc-
tors, higher residual currents often cause problems with detection or
when measuring the junction capacitance. With thyristors and triacs
often the firing currents or the holding currents are not reached. Accord-
ingly, it is possible that a thyristor is detected as an NPN transistor or
even as a diode. Likewise, it is possible that a thyristor or triac is not de-
tected at all. There are also problems with the recognition of semi-
conductors with integrated resistors. Therefore, also the base-emitter
diode of a BU508D transistor is not detected because of a parallel
connected internal 42Ω resistor. Accordingly, the transistor function can-
not be tested. When detecting Darlington transistors with higher power,
there are often also problems. Here also often base-emitter resistors are
installed, which complicate the detection because of the small measuring
currents used here. www.joy-it.net
