electric current fl ows or of charged capacitors. For measuring high resistance resistors or high capacitance ca-
pacitors the measurement may take a few seconds for the result to stabilise; this is a normal reaction when measuring
large values. In the resistance measurement mode, before applying the measuring tips to the measured element, an
overload symbol is shown on the display.
Diode test/conduction test
Connect the measurement cables to the jacks marked VΩHz% and COM and set the selector to the diode symbol.
By default, this mode measures the continuity of the electrical circuit; after pressing the SEL button you can test the
diodes. Pressing the SEL button again allows entering automatic mode, where the meter itself selects whether to test
the diodes or measure continuity. Press the SEL button again to return to the conduction measurement. Apply the tips
of the measurement cables to the ends of the measured element. In the case of a conduction test, the continuity of
the cable will be indicated by a buzzer. If the resistance of the circuit under test is between 15 Ω and 30 Ω, the green
indicator lamp will light up and the buzzer will emit an intermittent signal. In the case of testing diodes, the display
shows the value of the conduction voltage, usually 0.5-0.8 V or the symbol "OL" if the diode is tested in the negative
direction. In automatic mode, if the resistance of the measured element is in the range of 15 Ω to 100 Ω then the
meter tests the conduction. It is absolutely forbidden to test diodes or conduction if an electric current fl ows
through the circuit under test.
Frequency measurement / Fill factor measurement
Connect the measurement cables to the jacks marked VΩHz% and COM. Set the selector to the position marked Hz%.
The display shows simultaneously the result of the frequency measurement and the fi ll factor of the measured signal.
Temperature measurement
Move the measurement switch to the temperature measurement position (°C/°F). The display will show the ambient tem-
perature around the meter. It is also possible to connect the thermocouple terminals to the VΩHz% and COM jacks. The
thermocouple supplied with the product permits measurement of only up to 230 C. To measure higher temperatures,
o
a thermocouple designed for measuring higher temperatures must be purchased. Use type K thermocouples. With the
SEL button, you can select either the C or F measurement unit. The default temperature measurement unit is °C.

Non-contact AC voltage detection
The meter has a sensor that can detect the electromagnetic fi eld generated by AC voltage. Move the selector to the
NCV position, this will be confi rmed by the "NCV" display indicator and the "----" symbol. Bring closer the NCV sensor
in the front plate of the meter to the point to be checked in terms of electromagnetic fi eld presence. If a fi eld of low
intensity is detected, the meter will display the "---L" symbol, the green diode lights up. If a high intensity electromag-
netic fi eld is detected, the meter displays the "---H" symbol, the red diode lights up and sound is emitted by the buzzer.
This measurement can be used, for example, to detect hidden AC voltage wires. However, it should be remembered
that such a measurement is aff ected by many external factors and may be disturbed by external electromagnetic
fi elds. Do not rely solely on this method to detect live wires.
Contact voltage detection
Move the selector to the „Live" position, connect a single cable to the VΩHz% jack. Apply the measuring tip to the
measured element, if it is live, the display will show the "LIVE" symbol, the green indicator lamp lights up and an
acoustic signal is emitted by the buzzer.
LEAD message
The LEAD message appears on the screen when you try to measure with test leads that are not properly connected
to the meter's sockets. For example, trying to measure electric voltage with the wires connected, as if measuring
current. When the LEAD message appears on the meter display. Turn off the meter, check whether the test leads are
connected to the appropriate meter sockets and the selector indicates the correct measurement value. Then turn the
meter back on and repeat the measurement.
