5. Opsætning
5.1 Batteriinstallation
- Sørg for, at måleren er slukket.
- Find batterirummet på bagsiden af måleren.
- Brug en skruetrækker til at løsne skruen, der fastgør batteridækslet.
- Fjern batteridækslet.
- Isæt et nyt 9V batteri, og overhold den korrekte polaritet.
- Sæt batteridækslet på igen og fastgør det med skruen.
5.2 Tilslutning af testledninger
Always connect the black test lead to the COM (common) terminal. Connect the red test lead to the appropriate input terminal based on the measurement function:
- VΩHz: For volumentage. modstands-, frekvens-, kapacitans- og diode-/kontinuitetsmålinger.
- mAµA: For milliampere og mikroamperestrømsmålinger.
- 10A: For high current (up to 10A) measurements.

6. Betjeningsvejledning
The AM-570 features a rotary dial for selecting primary measurement functions and push buttons for secondary functions and settings.
6.1 Funktionsvalg
Turn the rotary dial to the desired measurement function. Use the VÆLGE button to toggle between primary and secondary functions within a single dial position (e.g., AC/DC voltage, modstand/kontinuitet/diode).
6.2 Målefunktioner
- Voltage (V~ / V--): Select the V~ (AC) or V-- (DC) position. Connect test leads in parallel with the circuit.
- Current (10A / mAµA): Select the 10A or mAµA position. Connect the meter in series with the circuit. Ensure correct terminal connection.
- Modstand (Ω): Select the Ω position. Ensure power is off and capacitors are discharged. Connect test leads across the component.
- Continuity ())): Select the Ω position and press VÆLGE until the continuity symbol appears. A continuous beep indicates continuity.
- Diode Test (→|): Select the Ω position and press VÆLGE until the diode symbol appears. Connect leads across the diode.
- Kapacitans (F): Select the F position. Ensure power is off and capacitors are discharged. Connect leads across the capacitor.
- Frequency (Hz) / Duty Cycle (%): Select the Hz% position. Connect leads to the signal source. Press VÆLGE to toggle between frequency and duty cycle.
- Temperatur (° C / ° F): Select the TEMP °C/°F position. Insert K-type thermocouple probes into the T1 and T2 inputs. Press VÆLGE to toggle between Celsius and Fahrenheit.
- Non-Contact Voltage (NCV): Select the NCV position. Hold the top of the meter near a live conductor. The NCV indicator and audible alarm will activate if voltage er opdaget.
- Low Z Mode: Select the LoZ V~ position for AC voltage measurements with low impedance. This helps to eliminate ghost voltages.
- Lavpasfilter: Activated automatically in certain AC voltage modes, this filter allows for accurate measurements on variable frequency drives.
6.3 Specialfunktioner
- RANGE: Manually select the measurement range instead of auto-ranging.
- REL (Relative Mode): Measures the difference between a stored reference value and the current reading.
- MAX/MIN: Records the maximum and minimum values over a measurement period.
- HOLDE: Fryser den aktuelle displayaflæsning.
- PEAK (1ms): Captures fast transient peaks (positive and negative) with a 1ms response time.
