FAQ

1)What are the power supply options for the MEFJ-WM2 SF6 Comprehensive Tester?

Answer: This instrument supports two power supply methods: AC 220V power supply (via power adapter, which simultaneously powers the instrument and charges the battery), and built-in lithium battery power supply (suitable for outdoor operations, providing over 8 hours of continuous operation).

2)Under what environmental conditions should measurements be avoided when using the MEFJ-WM2 SF6 Comprehensive Tester?

Answer: Measurements are prohibited in the following environments: environments containing toxic or corrosive gases; rainy conditions (to prevent water ingress); and environments exceeding the specified temperature range (-20°C to +50°C) and humidity range (5% to 95% RH).

3)What improper operations should be avoided during routine maintenance of the MEFJ-WM2 SF6 Comprehensive Tester?

Answer: Improper operations to avoid during routine maintenance include:
- Avoid impacts or severe vibrations; handle with care.
- Prevent exposure to rain or direct sunlight.
- Keep dust, corrosive gases, conductive objects, liquids, and flammable/explosive materials away from the instrument.
- Do not leave the power cord connected during prolonged periods of non-use.
