4. Taking Measurements
Notice:
ƒ Connect the red measuring cable to the anode of the Diode (Diode
end without ring mark) and the black measuring cable to the cath-
ode.
ƒ If a value of up to 3 V is displayed, the component is functional in
forward direction. The forward voltage is displayed. If overflow “1” is
displayed, the diode is defective.
ƒ Now turn around the diode (red + to the cathode and black - to the
anode). If overflow “1” is displayed, the diode correctly blocks. It is
functional in reverse direction. If the unit displays any voltage, the
diode is defective.
4.7 Frequency Measurement
The unit can be used to measure frequencies of up to 20 kHz.
Important Notice!
The input voltage should be between 1 V and 10 V. If the input voltage
is higher, an accurate result can not be guaranteed and the instrument
may be damaged.
Measuring Procedure
1. Connect the red measurement cable to the V/
Ω /F/°C/ -Input (9)
and the black measurement cable to the COM-Input (8).
2. Set the rotary switch (4) to “20kHz”. This is confirmed by „kHz“
being displayed.
3. Now hold the measuring tips to the circuitry or component to be
measured and read the frequency from the display.
