FAQ

1)What precautions should be taken when operating the MEFJ-WM5Q SF6 Comprehensive Tester via its touchscreen?

Answer: Simply press the on-screen buttons lightly with your finger during operation. Avoid tapping with sharp or hard objects, as this may shorten the touchscreen's lifespan or cause damage.

2) In what scenarios is the cleaning function of the MEFJ-WM5Q SF6 Comprehensive Tester primarily used?

Answer: The cleaning function is primarily used in the following two scenarios:
First, when the concentration of decomposition components in the measured gas is found to be excessively high, exceeding the sensor's measurement range and potentially damaging the sensor, immediately disconnect the quick-connect fitting at the inlet end and activate the cleaning system to reduce the concentration of decomposition components to near zero. Second, when the measured gas contains decomposition components and testing is complete, activate the cleaning system to flush out these components before packing the instrument for storage. This practice extends sensor lifespan.

3)What environmental requirements must be met when storing the MEFJ-WM5Q SF6 Comprehensive Tester?

Answer: Storage must meet the following environmental requirements: temperature range of -20°C to 50°C, relative humidity ≤95%, atmospheric pressure of 70–106 kPa, and the storage environment must be free of corrosive gases. Additionally, simply close the flow control valve on the tubing; do not forcefully tighten it to prevent damage to the valve.
