How to Use the ZL128B Multimeter
1. Basic Setup
- Power On: Press the power button; the backlit LCD will activate.
- Select Mode: Rotate the dial to choose the desired function (e.g., voltage, resistance).
- Connect Probes: Insert the black probe into the COM port and the red probe into the appropriate jack (e.g., VΩ for voltage/resistance, 10A for high current).
2. Measuring Voltage
- DC Voltage: Set dial to V⎓, touch probes to the circuit (red to +, black to -).
- AC Voltage: Set dial to V~, place probes across the AC source.
3. Testing Continuity & Resistance
- Continuity: Set to continuity mode (⎓)), touch probes to wire ends—a beep confirms a closed circuit.
- Resistance: Set to Ω, place probes across a resistor (ensure power is off).
4. Checking Current
- DC/AC Current: Switch to A⎓ or A~, connect in series with the circuit (use the 10A jack for high currents).
5. Using NCV Detection
- Non-Contact Voltage: Hold the multimeter near a wire—an alarm or light indicates live voltage.
6. Temperature Measurement
- Insert the temperature probe into the designated port, touch the probe to the surface, and read the display.
7. Auto Power-Off & Data Hold
- The ZL128B has auto power-off to save battery. Press HOLD to freeze readings for recording.
