2. Važne informacije o sigurnosti

Always adhere to the following safety precautions to prevent personal injury and damage to the instrument:

• Read this manual thoroughly before using the multimeter.
• Ne prekoračujte maksimalna ograničenja unosa za bilo koju funkciju.
• Never use the meter if it or the test leads appear damaged.
• Budite oprezni pri radu s volumomtagiznad 30V AC RMS, 42V peak ili 60V DC. Ovi volumenitagpredstavljaju opasnost od strujnog udara.
• Uvijek isključite mjerne kablove iz strujnog kola prije promjene funkcija ili raspona.
• Osigurajte da su za mjerenje odabrani ispravna funkcija i raspon.
• Odmah zamijenite baterije kada se pojavi indikator slabe baterije.
• Ne koristite mjerač u okruženjima eksplozivnog plina, pare ili prašine.

4.2 Spajanje mjernih kabela

To prepare the multimeter for measurements:

1. Umetnite crni mjerni kabel u ulazni priključak 'COM' (Common).
2. Umetnite crveni mjerni kabel u odgovarajući ulazni priključak za mjerenje:
• 'VΩHz%CAP' for Voltage, Resistance, Frequency, Duty Cycle, and Capacitance measurements.
• '10A' for current measurements up to 10A (or 20A max for 30 seconds).
• 'µAmA' for microampere and milliamptrenutna mjerenja.

5. Uputstvo za upotrebu

The IRONMETER features a large LCD with backlight for clear readings and a rotary dial for function selection.

5.1 Power On/Off and Auto Power Off

• To turn the meter ON, rotate the function dial from 'OFF' to any desired measurement function.
• To turn the meter OFF, rotate the function dial to the 'OFF' position.
• The meter features an Auto Power Off function to conserve battery life. It will automatically power off after a period of inactivity.

5.2 Funkcije mjerenja

5.2.1 AC/DC Voltage Measurement (0.001 V to 600 V)

Podesite rotirajući brojčanik na 'V~' (AC Voltage) ili 'V=' (DC Voltage) position. Connect the test leads in parallel to the circuit or component under test. The display will show the voltage čitanje.

5.2.2 AC/DC Current Measurement (0.1 µA to 10 A, 20 A max for 30 sec)

Set the rotary dial to the 'µAmA~', 'µAmA=', '10A~', or '10A=' position. Connect the test leads in series with the circuit. Ensure the correct input jack (µAmA or 10A) is used based on the expected current. The display will show the current reading.

5.2.3 Resistance Measurement (0.1 Ω to 40 MΩ)

Set the rotary dial to the 'Ω' position. Connect the test leads across the component to measure its resistance. Ensure the component is de-energized before measuring resistance.

5.2.4 Continuity and Diode Test

Set the rotary dial to the 'Diode/Continuity' position. For continuity, connect the leads across the circuit; a low resistance will trigger an audible beep. For diode test, connect the leads across the diode; the display will show the forward voltage drop.

5.2.5 Frequency Measurement (up to 10 kHz)

Set the rotary dial to the 'Hz' position. Connect the test leads to the signal source. The display will show the frequency in Hertz.

5.2.6 Capacitance Measurement (0.01 nF to 4000 µF)

Set the rotary dial to the 'CAP' position. Connect the test leads across the capacitor. Ensure the capacitor is discharged before measurement. The display will show the capacitance in Farads.

5.3 Posebne funkcije

5.3.1 Zadržavanje podataka

Pritisnite dugme 'HOLD' da biste zamrznuli trenutno očitanje na ekranu. Ponovo pritisnite da biste isključili funkciju zadržavanja.

5.3.2 Max/Min funkcija

Press the 'MAX/MIN' button to activate the maximum/minimum value recording. The meter will continuously record the highest and lowest readings. Press again to cycle between MAX, MIN, and current readings.

5.3.3 Radni ciklus

When in Frequency mode, the 'MODE' button may allow switching to Duty Cycle measurement, displaying the ratio of pulse width to period.

5.3.4 Pozadinsko osvjetljenje i svjetiljka

The IRONMETER features a large LCD with backlight for improved visibility in low-light conditions. Press the backlight button (often integrated with the 'MODE' or a dedicated light button) to activate it. An integrated white LED flashlight is also available for illuminating the work area.

6. Održavanje

6.1 Zamjena baterije

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use fresh AAA batteries.

6.2 Čišćenje

Za čišćenje multimetra, obrišite kućište sredstvom za čišćenje.amp krpom i blagim deterdžentom. Ne koristite abrazivna sredstva ili rastvarače. Prije upotrebe provjerite je li mjerač potpuno suh.

7. Otkrivanje problema

If you encounter issues with your IRONMETER, refer to the following common problems and solutions:

• Nema prikaza/Mjerač se ne uključuje: Provjerite jesu li baterije ispravno postavljene i uvjerite se da nisu ispražnjene. Zamijenite ih ako je potrebno.
• Netačna očitanja: Verify that the correct function and range are selected. Ensure test leads are properly connected and not damaged. Check for proper circuit connection.
• 'OL' or 'OVER' Display: Indicates an overload or out-of-range measurement. Select a higher range or ensure the input is within the meter's specifications.
• Povremena očitanja: Check for loose connections at the test leads or within the circuit.

Ako problem i dalje postoji nakon isprobavanja ovih rješenja, obratite se korisničkoj podršci.
