5. Configurarea și instalarea bateriei

5.1 Instalarea bateriei

The MS2108 requires 3 x 1.5V AAA batteries (not included). To install:

1. Asigurați-vă că aparatul de măsură este oprit.
2. Localizați capacul compartimentului bateriilor pe spatele contorului.
3. Folosiți o șurubelniță pentru a deschide compartimentul bateriei.
4. Insert three AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Puneți la loc capacul compartimentului bateriei și fixați-l cu șurubul.

5.2 Conectarea cablurilor de testare

Pentru voltage, resistance, capacitance, frequency (from test terminal), continuity, and diode measurements, connect the test leads:

• Insert the red test lead into the 'INPUT' jack.
• Introduceți sonda neagră de testare în mufa „COM” (comună).

6. Instrucțiuni de utilizare

6.1 Selector de funcții

Rotiți selectorul central pentru a selecta funcția de măsurare dorită:

• OPRIT: Oprește contorul.
• V~: AC Voltage măsurare.
• V-: DC Voltage măsurare.
• A~: AC Current measurement (using clamp).
• LA-: DC Current measurement (using clamp).
• Ω K Å: Resistance, Continuity, Diode, Capacitance measurement. Use the 'SEL' button to cycle through these functions.
• Hz%: Frequency and Duty Cycle measurement.

6.2 Funcțiile butoanelor

• SEL (Yellow Button): Selects sub-functions within a main dial position (e.g., AC/DC, Ohm/Diode/Continuity).
• MINIM MAXIM: Toggles between minimum and maximum recorded values during a measurement session.
• A FUGIT: Toggles between auto-ranging and manual ranging. In manual range, press repeatedly to cycle through ranges.
• Hz/%: When in Voltage or Current mode, press to display frequency or duty cycle.
• B.L. HOLD: Short press to activate/deactivate data hold (freezes the current reading). Long press (2 seconds) to turn the backlight ON/OFF.
• Inrush: Press this button when the dial is in an AC/DC current position to measure inrush current.

6.3 Proceduri de măsurare

Măsurarea curentului AC/DC (Clamp):

1. Turn the function dial to the A~ (AC) or A- (DC) position.
2. Deschide clamp jaw and enclose a single conductor. Ensure the jaw is fully closed.
3. Citiți valoarea curentului de pe afișaj. Pentru curent continuu, respectați polaritatea.

AC / DC Voltage Măsurare:

1. Connect the test leads to the 'INPUT' and 'COM' jacks.
2. Turn the function dial to V~ (AC) or V- (DC).
3. Conectați sondele de testare în paralel cu circuitul sau componenta testată.
4. Citiți voltage valoarea pe display.

Resistance, Continuity, Diode, Capacitance Measurement:

1. Conectați sondele de testare.
2. Turn the function dial to the Ω K Å position.
3. Press the 'SEL' button to cycle through Resistance (Ω), Continuity (K), Diode (Å), and Capacitance (uF) functions.
4. Connect the test probes to the component. For continuity, a buzzer will sound if resistance is below approximately 50Ω.

Măsurarea curentului de pornire:

1. Set the function dial to A~ or A-.
2. Press the 'Inrush' button. The display will show 'Inr'.
3. Deschide clamp jaw and enclose the conductor of the device you wish to test the inrush current for (e.g., motor, compressor).
4. Activate the device. The meter will capture and display the peak inrush current.

7. Întreținere

7.1 Curățare

Ștergeți carcasa contorului cu reclamăamp o lavetă și un detergent blând. Nu utilizați substanțe abrazive sau solvenți. Nu lăsați terminalele de intrare să fie curățate de murdărie sau resturi.

7.2 Înlocuirea bateriei

When the battery symbol appears on the display, replace the batteries as described in Section 5.1. Remove batteries if the meter is not used for extended periods.

7.3 Depozitare

Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for a long period, remove the batteries.
