Warning: Always ensure the multimeter is turned OFF and disconnected from any circuits before opening the battery compartment.
4. Operasyon Enstriksyon
4.1 Power On/Off
To turn on the multimeter, rotate the knob switch from the 'OFF' position to any desired measurement function. To turn off the multimeter, rotate the knob switch back to the 'OFF' position. The device features an automatic power-off function to save battery life if left idle for a period.
4.2 Mezi Debaz yo
The DM Mini is an auto-ranging multimeter, simplifying operation by automatically selecting the appropriate measurement range.
4.2.1 vòltagMezi (AC/DC)
Pou mezire voltage:
- Rotate the knob switch to the 'V=' (DC Voltage) or 'V~' (AC Voltage) pozisyon.
- Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side (for DC) or across the points for AC.
- Li voltage valè sou ekspozisyon LCD a.
Figi 4.1: Examples of measuring DC voltage from a 9V battery and AC voltage from a power outlet using the multimeter.
4.2.2 Mezi Rezistans (Ω)
Pou mezire rezistans:
- Rotate the knob switch to the 'Ω' (Resistance) position.
- Ensure the circuit is de-energized before connecting the test leads across the component to be measured.
- Li valè rezistans lan sou ekran LCD a.
4.2.3 Tès Kontinuite (♫)
Pou fè yon tès kontinite:
- Rotate the knob switch to the '♫' (Continuity) position.
- Konekte fil tès yo atravè sikwi a oswa konpozan an.
- If there is continuity (low resistance), the multimeter will emit an audible beep.
4.2.4 Diode Test (†)
Pou teste yon dyod:
- Rotate the knob switch to the '†' (Diode) position.
- Konekte fil tès wouj la nan anod la epi Konekte fil tès nwa a nan katod dyòd la.
- Obsève pi devan voltage drop on the display. Reverse the leads to check for open circuit (OL) in reverse bias.
4.2.5 Mezi Kapasitans (F)
Pou mezire kapasite:
- Rotate the knob switch to the 'F' (Capacitance) position.
- Asire w ke kondansateur a dechaje nèt anvan ou konekte fil tès yo.
- Konekte fil tès yo atravè kondansateur a.
- Li valè kapasite a sou ekspozisyon LCD a.
4.2.6 Frequency and Duty Cycle Measurement (Hz/DUTY)
To measure frequency or duty cycle:
- Rotate the knob switch to the 'Hz/DUTY' position.
- Konekte fil tès yo ak sous siyal la.
- The display will show the frequency (Hz). Press the 'RANGE' button to toggle to duty cycle measurement.
4.3 Fonksyon kenbe done
Press the 'H' (Data Hold) button to freeze the current reading on the display. Press it again to release the hold and resume live readings.
