1. Odšroubujte zadní kryt multimetru.
2. Vložte dvě baterie typu AA a dbejte na správnou polaritu (+/-).
3. Nasaďte zpět zadní kryt a zajistěte jej šroubem.

5.2 Připojení měřicích vodičů

Proper connection of test leads is crucial for accurate and safe measurements. The multimeter features an intelligent LED Jack Indicator to guide you:

1. Otočte otočný volič na požadovanou funkci měření.
2. The corresponding input jacks will light up (green light reminder).
3. Zasuňte černý měřicí vodič do zdířky „COM“ (common).
4. Insert the red test lead into the illuminated input jack appropriate for your measurement (e.g., 'INPUT' for voltage/resistance, 'mA' or '20A' for current).

6. Návod k obsluze

To operate the ANENG SZ11 Multimeter, select the desired function using the rotary dial and connect the test leads as indicated by the LED jack lights.

6.1 DC svtage Měření

Turn the dial to the 'V=' position. Connect the red test lead to the positive terminal and the black test lead to the negative terminal of the DC source. The display will show the DC voltage. Measurable up to 1000V.

6.2 AC svtage Měření

Turn the dial to the 'V~' position. Connect the test leads across the AC source. The display will show the AC voltage. Press the 'FUNC' button to switch between AC and DC if needed. Measurable up to 750V. The MAX/MIN button can be used to display the maximum or minimum detected voltage.

6.3 Millivolt DC/AC Voltage Měření

Pro malý objemtage measurements, turn the dial to the 'mV' position. Press the 'FUNC' button to toggle between DC and AC millivolts. This mode offers high precision for sensitive measurements.

6.4 Měření frekvence (Hz) a pracovního cyklu

Turn the dial to the 'Hz%' position. Connect the test leads to the circuit where frequency or duty cycle needs to be measured. Press 'FUNC' to switch between Frequency (Hz) and Duty Cycle (%).

6.5 Test kontinuity

Turn the dial to the 'Ω' position and press 'FUNC' until the continuity symbol (a speaker icon) appears. Touch the test leads to the two points of the circuit. A beep indicates continuity (a complete circuit). This function is useful for locating broken lines or checking fuses.

6.6 Měření odporu

Turn the dial to the 'Ω' position. Connect the test leads across the component to measure its resistance. The multimeter will auto-range to provide the reading. Ensure the circuit is de-energized before measuring resistance.

6.7 Test diod

Turn the dial to the 'Ω' position and press 'FUNC' until the diode symbol appears. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reversing the leads should show an open circuit (OL) for a healthy diode. This can also light up small lamp korálky.

6.8 Měření kapacity

Turn the dial to the 'F' position. WARNING: Always discharge capacitors before testing to prevent damage to the multimeter. Connect the test leads across the capacitor. The display will show the capacitance value.

6.9 Měření teploty

Turn the dial to the '°C/°F' position. Connect the temperature probe to the input jacks. Place the probe on the object whose temperature you wish to measure. Press 'FUNC' to switch between Celsius and Fahrenheit.

6.10 Current Measurement (µA, mA, A)

WARNING: Current measurements require connecting the multimeter in series with the circuit. Incorrect connection can damage the multimeter or the circuit.

• Microampere (µA) / Milliampere (mA) DC/AC Current: Turn the dial to the 'µA' or 'mA' position. Press 'FUNC' to select AC or DC. Connect the multimeter in series with the circuit. The maximum measurable current is 600mA.
• Ampere (A) DC/AC Current: Turn the dial to the '20A' position. Press 'FUNC' to select AC or DC. Connect the multimeter in series with the circuit. The maximum measurable current is 20A.

6.11 NCV (bezkontaktní objemtage) Snímání

Turn the dial to the 'NCV' position. Bring the top of the multimeter close to an AC voltage source (e.g., a live wire). The display will show dashes, and the device will beep, indicating the presence of AC voltage. The closer the multimeter is to the voltage, the more urgent the beeping and screen flickering will be. This function can also be used to locate breakpoints in a line.

6.12 Detekce vodičů pod napětím

Turn the dial to the 'LIVE' position. Insert the red test lead into the 'INPUT' jack. Touch the red test lead to a wire. If it's a live wire, the screen will show 'LVE' and beep. If it's a neutral line, there will be no response.

6.13 Svítilna a podsvícení

To activate the flashlight, press the flashlight button. To turn on the backlight for the display, long-press the backlight button. These features are useful for working in dark environments.

7. Údržba

7.1 Čištění

Otřete multimetr casing s reklamouamp cloth. Do not use abrasive cleaners or solvents. Ensure the device is off and disconnected from any power source before cleaning.

7.2 Výměna pojistky

The ANENG SZ11 Multimeter has built-in fuses for protection. If the multimeter stops functioning correctly, especially during current measurements, the fuses may need replacement. The µA/mA fuse is F600mA/250V, and the 20A fuse is F20A/250V. To replace a fuse:

1. Ensure the multimeter is OFF and disconnect all test leads.
2. Unscrew the back case of the multimeter.
3. Carefully remove the old fuse using tweezers.
4. Insert a new fuse of the correct type and rating.
5. Reassemble the back case and secure it with screws.

8. Řešení problémů

If you encounter issues with your ANENG SZ11 Multimeter, consider the following common troubleshooting steps:

• Žádný displej/Slabá baterie: Check battery installation and replace batteries if low.
• Nesprávné čtení: Ensure the correct function and range are selected. Verify test lead connections. Clean test lead tips if corroded.
• Displej „OL“: This typically indicates an overload (measurement exceeds the selected range) or an open circuit (no continuity). Adjust the range or check the circuit.
• Žádné měření proudu: Check if the appropriate fuse (µA/mA or 20A) has blown and replace if necessary. Ensure the multimeter is connected in series.
• Nepřesné hodnoty odporu: While the multimeter offers good accuracy, some budget multimeters may show slight variations on certain resistance ranges. For critical measurements, consider professional-grade equipment.
