The device operates with a special temperature
measurement probe. If the probe is not connected to
the connector, the device shows the temperature of its
environment.
Do not connect external voltage to the connectors if the
device is in temperature measurement mode.
Transistor hFE test

Description
Measures the

factor of the
FE
transistor(0-1000)
(All types)
U
sage
The signs near the connectors warn if the
•
inward voltage or current values are above the
set values. These help to avoid damage to the
inner circuits.
Set the proper function with the function
•
selection switch before measuring.
If you do not know the measured value range,
•
set the switch to the highest available setting
and go backwards until you reach the proper
setting.
DC and AC voltage measurement
Connect the black wire to the „COM" connector
•
and the red one to the „VΩHz" connector.
By default the automatic range switch is
•
active, which is indicated by the AUTO sign on
the display. You can set the following ranges
manually by pressing the RANGE button: 400
mV/4 V/40 V/400 V/1000 V.
Set the function selection switch to the proper
•
V setting and connect the wires parallelly for
the measurement.
DC and AC current measurement
Connect the black wire to the „COM", and the
•
red one to the „mA" or „10A" connectors for 400
mA or 10A measurement.
Set the proper range with the function switch.
•
Connect the connectors to the power source
•
parallelly.
To measure current between 400 mA and 10 A
•
follow the instructions above, but connect the
red wire to the „10A" connector.
Resistance measurement
Connect the black wire to the „COM" and the
•
red one to the „V/ΩHz" connector.
Set the function switch to the desired
•
resistance range.
Connect the wires parallelly.
•
Press the "RANGE" button for selecting the
Test state
•
automatic/manual range.
Warning: Make sure the measured circuit is not under
Base current

setting.
Press the „REL" button to clear the display.
•
Connect the black wire to the „COM" and the
•
red one to the „V/Ω" connector. Touch the
wires to the connectors of the capacitor. Pay
attention to the polarity.
Note:
Capacity measurement has automatic range selection.
Unit: 1 nF=10
Do not connect an external voltage source or a
charged capacitor (especially high capacity ones)
to the connectors. Discharge the capacitors before
measurement. Electrolyte capacitors should be
discharged multiple times.
Diode and continuity test
Connect the black wire to the „COM" connector
•
and the red one to the „VΩHz" connector.
(Note: the polarity of the red wire is +)
Set the function switch to the
•
Touch the wires to the connectors of the
•
diode. The display shows the opening voltage
of the diode.
Connect the wires to the two points of the
•
circuit. If the resistance is below 50 Ω, the
device will beep.
Transistor hFE test
Set the function switch to the hFE position.
•
Determine whether the transistor is NPN or
•
PNP and place it into the proper connector
(this connector is included and connects to the
mA + COM connectors).
The transistor's amplification factor is
