5.1 Негізгі өлшемдер

1. Тtage (AC/DC) Measurement:
   Turn the rotary switch to the 'V~' (AC Voltage) немесе 'V-' (Тұрақты ток көлеміtage) position. Connect the test leads in parallel to the circuit or component to be measured. The reading will appear on the LCD.
2. Current (AC/DC) Measurement:
   Turn the rotary switch to the 'A~' (AC Current) or 'A-' (DC Current) position, selecting the appropriate range (µA, mA, or 20A). Connect the test leads in series with the circuit.
3. Қарсылықты өлшеу:
   Turn the rotary switch to the 'Ω' position. Connect the test leads across the component. Ensure the circuit is de-energized before measuring resistance.
4. Сыйымдылықты өлшеу:
   Turn the rotary switch to the 'F' (Capacitance) position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement.
5. Температураны өлшеу:
   Turn the rotary switch to the '°C/°F' position. Connect the K-type thermocouple (included) to the input terminals. The temperature will be displayed.
6. Frequency (Hz) Measurement:
   Turn the rotary switch to the 'Hz' position. Connect the test leads to the signal source.
7. Диод сынағы:
   Turn the rotary switch to the 'Diode' symbol position. Connect the red lead to the anode and the black lead to the cathode of the diode. The forward voltage drop көрсетіледі.
8. Үздіксіздік сынағы:
   Turn the rotary switch to the 'Continuity' symbol position. Connect the test leads across the circuit or component. A buzzer will sound if continuity is detected.
