Always connect the black test lead to the 'COM' (Common) input jack. Connect the red test lead to the appropriate input jack based on the measurement you intend to perform:

• VΩHz: For Voltage, Resistance, Frequency, Diode, and Continuity measurements.
• mAFor milliamperestrømsmålinger.
• A: For amperestrømsmålinger.

Caution: Ensure test leads are correctly inserted into the appropriate jacks for the selected function to prevent damage to the meter or circuit.

6. Betjeningsvejledning

The ZT5566 features an auto-ranging display and is designed for ease of use. The LCD display provides clear readings, and the backlight brightness is adjustable for optimal visibility.

Figure 6.1: Multimeter Functionality Overview. This image illustrates the multimeter performing various measurements including Frequency, Resistance, Capacitance, and Buzzer (Continuity) tests, showing the display for each function.

6.1 Grundlæggende målinger

To perform a measurement, turn on the multimeter. The device will automatically select the appropriate range for most measurements (Auto Range). Select the desired function using the mode buttons.

• Voltage (AC/DC): Connect test leads in parallel to the circuit. Use the 'V~Hz' button to switch between AC and DC voltage.
• Strøm (AC/DC): Connect test leads in series with the circuit. Use the 'mA' or 'A' input jacks and the corresponding function button.
• Modstand (Ω): Ensure the circuit is de-energized. Connect test leads across the component.
• Kapacitans: Ensure the capacitor is discharged before testing. Connect test leads across the capacitor.
• Diodetest: Connect test leads across the diode. The display will show the forward voltage drop.
• Kontinuitetstest: Connect test leads across the circuit or component. A buzzer will sound if continuity is detected (low resistance).
• Frekvens (Hz): Connect test leads to the circuit.
