Configuració
Instal·lació de la bateria:
Both the SZ301 Multimeter and VC1019 Pen Tester require batteries for operation. The package includes 4x 1.5V AAA batteries.
- Locate the battery compartment on the back of each device.
- Obriu la tapa de la bateria.
- Insert the AAA batteries, ensuring correct polarity (+ and -).
- Tanqueu la tapa de la bateria amb seguretat.

Figura 4: The product package includes the necessary AAA batteries for both devices.
Connecting Test Leads (for SZ301 Multimeter):
For most measurements, connect the red and black test leads to the appropriate input jacks on the multimeter.
- Inseriu el cable de prova negre al connector "COM" (comú).
- Per al voltage, resistance, capacitance, and diode measurements, insert the red test lead into the "VΩmA+" jack.
- For current measurements (up to 10A), insert the red test lead into the "10A" jack. For smaller currents (mA), use the "VΩmA+" jack.
Instruccions de funcionament
Using the ANENG SZ301 Multimeter:
Turn the rotary dial to the desired measurement function. The display will show the reading.
1. AC/DC Voltage Mesura:
- Set the rotary dial to the "V~" (AC Voltage) o "V-" (Volumen de CCtage) abast.
- Connecteu els cables de prova en paral·lel al circuit o component que es mesura.
- Llegeix el voltage valor a la pantalla.

Figura 5: Mesurar AC voltage using the ANENG SZ301 Multimeter.
2. Current Measurement (AC/DC):
- Important: Connecteu el multímetre en sèrie amb el circuit.
- Set the rotary dial to the "A~" (AC Current) or "A-" (DC Current) range.
- Ensure the red test lead is in the appropriate current jack (10A or VΩmA+ for mA).
- Llegiu el valor actual a la pantalla.
3. Resistance Measurement:
- Set the rotary dial to the "Ω" (Ohms) range.
- Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
- Connecteu els cables de prova a través del component.
- Llegiu el valor de la resistència.
4. Prova de continuïtat:
- Set the rotary dial to the continuity symbol (often shared with diode or resistance).
- Connecteu els cables de prova a través del circuit o component.
- A continuous beep indicates a low-resistance path (continuity).
5. Prova de díodes:
- Set the rotary dial to the diode symbol.
- Connecteu el cable vermell a l'ànode i el cable negre al càtode del díode.
- A forward voltage drop will be displayed. Reverse the leads; an open circuit (OL) indicates a good diode.
6. Capacitance Measurement:
- Set the rotary dial to the "F" (Farad) range.
- Assegureu-vos que el condensador estigui completament descarregat abans de fer la prova.
- Connecteu els cables de prova a través del condensador.
- Llegiu el valor de la capacitança.
Using the ANENG VC1019 Pen Tester (Non-Contact Voltage Detector):
The VC1019 is designed for quick and safe detection of AC voltagi sense contacte directe.
1. NCV Detection:
- Turn on the VC1019.
- Bring the NCV inductive probe tip near a terminal strip, outlet, or insulated wire.
- Si AC voltage is detected, the tip will glow red, and the device will beep. The voice broadcast function will announce "Danger! High Voltage" or "low voltage" depending on the detected field strength.

Figura 7: The VC1019 Pen Tester's ability to differentiate between live (firewire) and neutral (zero line) connections.
2. Live Wire Detection:
- The device automatically identifies live or neutral wires. A stronger indication (faster beeping, brighter light, "Danger! High Voltage" voice) typically signifies a live wire.
3. Funció de llanterna:
- Press the designated button (refer to device markings) to activate the built-in flashlight for illumination in dark environments.
4. Infrared Laser Positioning:
- Some models feature an infrared laser for precise targeting. Activate it via the corresponding button.
