2. Safety Information
Always adhere to basic safety precautions when using electrical testing equipment to reduce the risk of fire, electric shock, or personal injury. Failure to follow these safety rules may result in severe injury or death.
- Do not use the devices if they appear damaged or if the insulation on test leads is compromised.
- Ensure your hands are dry and you are standing on an insulated surface when making measurements.
- Do not apply more than the rated voltage, as marked on the device, between the terminals or between any terminal and earth ground.
- Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
- Disconnect power to the circuit and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
- Always use the correct function and range for measurements.
- Replace the battery as soon as the low battery indicator appears to ensure accurate readings.
- For the GFCI Outlet Tester, use caution on regular outlets as testing may cause wiring to trip.

3.3. Operating Instructions
Turn the rotary dial to select the desired measurement function. The multimeter is auto-ranging, simplifying the measurement process.
- Voltage (AC/DC): Select the V~ (AC) or V- (DC) position. Connect the test leads in parallel to the circuit or component.
- Current (AC/DC): Select the A~ (AC) or A- (DC) position. Connect the multimeter in series with the circuit. Ensure the correct current jack (mA or 10A) is used.
- Resistance (Ω): Select the Ω position. Ensure the circuit is de-energized. Connect the test leads across the component.
- Continuity: Select the continuity position (often shared with resistance). A built-in buzzer will sound if the resistance is below a certain threshold.
- Diode Test: Select the diode symbol position. Connect the red lead to the anode and the black lead to the cathode of the diode.
- Capacitance (F): Select the F position. Ensure the capacitor is discharged before testing. Connect the test leads across the capacitor.
- Frequency (Hz) / Duty Cycle (%): Select the Hz/% position. Connect the test leads to the signal source.
- Temperature (°C/°F): Select the °C/°F position. Connect the K-Type thermocouple to the appropriate jacks.
- NCV (Non-Contact Voltage): Select the NCV position. Bring the top of the multimeter near an AC voltage source to detect its presence without direct contact.
- Live Wire Detection: Select the Live position. Use the red probe to touch the suspected live wire.
