Resistance measuring
•
Connect the black wire to the „COM” connector
and the red one to the V/Hz/Ω connector.
•
Set the function switch to the resistance
position and touch the wires to the two end
points of the resistor.
Note:
•
The „OL” sign means that the measured range is too
small and a higher range needs to be selected.
•
When measuring resistance make sure that the
measured circuit is not under power. Be careful as the
charged capacitors may also be dangerous.
•
Do NOT measure voltage in resistance mode because
this will damage the device.
•
If the measured value is not constant for a couple of
seconds when measuring above 1MΩ it is normal.
Capacity measurement
•
Set the device to the proper range and
connect the measuring wires to the „mA” and
„COM” connectors.
•
Connect the wires to the two end points of the
capacitor. Pay attention to the polarity: „COM”:
negative (black), and „mA”: positive (red)
Note:
•
The „OL” sign means that the measured range is too
small and a higher range needs to be selected.
•
The LCD display may show a couple of leftback numbers
when starting capacity measurement. This is normal and
will not have an effect on the measured result.
•
If you have high static charge is significant or the
capacitor gets broken in a high capacity range, the
displayed value will be incosistant and inaccurate.
•
Please discharge the capacitor before measuring to
avoid damage to the device.
Inductivity measurement
•
Set the device to the proper measuring range,
connect the wires to the „mA” and „COM”
connectors.
•
Touch the wires to the connecting points of
the coil.
Note:
•
The „OL” sign means that the measured range is too
small and a higher range needs to be selected.
•
The measured inductivity value for the same inductor
may differ because of the different impedance. When
measuring in the 2mH range touch the measuring wires
together, measure the inductivity of the wires and
subtract the value from the measured result.
•
Avoid the high range measuring of small coils as the
measured results will not be accurate.
Temperature measurement
•
Set the function switch to the „°C” position for
measuring temperature and connect the black
connector of the probe to the „mA” connector
on the device, and the red one to the „COM”
connector. Touch the probe to the surface of
the object you want to measure. The measured
value is displayed on the screen, the unit is
degrees celsius.
Note:
•
If the inward connector is not connected, the device
will show the temperature of its environment if the
operating temperature is above 18 C° and the normal
temperature if below 18 C°.
•
Do not remove the temperature measuring probe
temporally or the accuracy can not be guaranteed.
•
Do NOT connect voltage to the device in temperature
measuring mode.
Frequency measurement
•
Connect the wires to the „COM” and V/Ω/Hz
connectors.
•
Set the function switch to the frequency
position and connect the wires to the signal
source.
Note:
•
If the inward signal is lower than 10V RMS the accuracy
can not be guaranteed.
•
In an environment with much noise use a shielded cable
for measuring low values.
•
Do not use voltage above 250VAC peak value as it may
damage the device.
Transistor hFE
•
Set the device to „hFE” measuring mode.
•
Connect the connecting adapter to the „mA”
and „COM” connectors. Note the polarity:
„COM” is negative, „mA” is positive.
•
Determine the type of the transistor (NPN or
PNP) and connect the base, emitter, collector
pins to the proper connector.
Diode and continuity test
•
Connect the black wire to the „COM” connector
and the red one to the V/Ω/Hz connector (the
red will be the anode).
•
Set the device to the
position. Connect
the wires parallelly to the diode, the red to
the anode and the black to the cathode. The
displayed value is the approximate opening
voltage of the diode.
•
Touch the measuring wires to the two points
of the circuit, if you hear a beep, the the
resistance between the two points is lower
than 70Ω (±20)
