nents, for example, it can distin-
guish between different types of Battery 0.1 V - 4.5 V, 300 mAh
transistors, such as NPN or PNP Z-diode breakdown voltage 0.01 V - 30 V
transistors. The device is particu- Z-diode 0.01 V - 4.5 V

of a single button. Thyristor / Triac IGT < 6 mA
Thanks to the integrated 350 mAh
battery, measurements can also be
carried out on the road. The bat-
tery is charged with the help of a 5V
power supply unit (available sepa-
rately) and the enclosed micro-USB
cable.
In addition, this measuring device
can decode infrared signals and
show them as a waveform on the
display.

3. 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 to close the course 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 350 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 switches off automatically after 20 seconds of inactivity. You
can also turn it off manually by pressing and holding the Start button.

4. 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 informati-
on under Z-Diode.
You can always start the measurement with the start button. If nothing, a
defective part, or wrongly connected, this will be indicated on the screen.
Diode
Uf - forward voltage
C - capacity
Ir - leakage current
Z-Diode
Uz - 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
Uf - forward voltage
Triac
Uf - forward voltage
www.joy-it.net
Pascalstr. 8 47506 Neukirchen-Vluyn
Field effect transistor
Vt - breakdown 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
hFE - current amplifictaion factor
Ube - base voltage
Ic - collector current
Uf - forward voltage
Here the multifunction tester can distinguish between BJT-NPN, BJT-
NPN with diode, BJT-PNP and BJT-PNP with diode.
Batteries
The battery voltage is displayed here.
Attention! The battery must have less than 4.5 V, otherwise the mul-
tifunction 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 infra-
red remote control in front of the device, which decodes it immediately.
You can then see the UserCode and the DataCode 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.
