Warning Tips:

- Usage near devices with high electromagnetic interference may cause unstable readings or significant errors.

- Do not use the instrument if the appearance of the instrument or probes is damaged.

- Safety and Maintenance Habits:

- Incorrect usage may disable safety functions of the instrument.

- Extreme caution required when working around exposed conductors or busbars.

- Prohibited to use the instrument near explosive gases, vapors, or dust.

- Use correct input terminals, functions, and ranges for measurements, avoiding exceeding specified input limits to prevent instrument damage.

- Avoid touching unused input terminals when the instrument is connected to the circuit under test.

- Exercise caution when handling voltages exceeding 60V DC or 30V AC RMS to prevent electric shock.

- When using test probes, fingers should be placed behind the probe guard.

- Ensure test probes are removed from the circuit before changing ranges.

- For DC measurements, use AC function first to confirm the absence of AC voltage to prevent potential hazards from incorrect readings. Then, select a DC voltage range equal to or greater than the AC voltage.

- Before measuring resistance or conducting continuity tests, disconnect power to the circuit under test and discharge all high-voltage capacitors.

- Do not measure resistance or conduct continuity tests on live circuits.

- Avoid storing the instrument in flammable or explosive areas when not in use.

- Exercise caution when repairing televisions or measuring power conversion circuits to prevent damage from high-voltage pulses in the circuit under test.

- This product operates on a 3.7V/1000mA lithium battery, which must be correctly installed in the instrument's battery compartment.

- Recharge the battery promptly when the low battery symbol appears. Insufficient battery power may result in incorrect readings, potentially leading to electric shock or personal injury.

- Voltage measurements during measurement categories must not exceed 1000V.

- Do not use the instrument when its housing (or part of the housing) is removed.
