4.3 Oscilloscope Mode Operation

In Oscilloscope mode, the device displays waveforms. Key controls include:

• VOL/TIME: Adjusts vertical sensitivity (Volts/Div) and horizontal time base (Time/Div).
• LIIKKUA: Shifts the waveform horizontally or vertically.
• LAUKAISTA: Sets the trigger level and mode (Auto, Normal, Single) to stabilize the waveform.
• AC/DC Coupling: Selects AC or DC coupling for the input signal.
• Automaattinen kalibrointi: Use the auto calibration function for quick setup and optimal display of the waveform.

4.4 Multimeter Mode Operation

In Multimeter mode, the device functions as a digital multimeter. Use the ALUE painiketta tai AUTOMAATTINEN ALUE feature to select the appropriate measurement range. The device supports:

• AC/DC Voitage: Connect test leads to measure voltage.
• AC/DC-virta: Connect test leads to the appropriate current jacks (10A or mA) and select the current function.
• Resistanssi (Ω): Measure resistance by connecting leads across the component.
• Kapasitanssi: Mittaa kondensaattoreiden kapasitanssi.
• Taajuus (Hz): Measure signal frequency.
• Lämpötila (℃/℉): Use the temperature probe for measurements.
• Dioditesti: Testi diodit eteenpäin suuntautuvalle äänenvoimakkuudelletage pudota.
• Jatkuvuus: Check for circuit continuity with an audible beep.
