Maintenance & FAQs

 

Q: How to clean the load box?

A: Wipe the exterior with a clean, soft cloth. Avoid using corrosive cleaning agents. For internal components, regular inspection and dust removal are recommended, but avoid touching sensitive parts.

Q: What is the calibration cycle for the load box?

A: It is recommended to calibrate the device once a year to ensure measurement accuracy. If the operating environment is harsh, the calibration cycle should be shortened accordingly.

Q: What to do if there is a large measurement error during use?

A: First, check if the power supply voltage is stable. Then, confirm whether the device is operating within the specified environmental conditions. If the problem persists, contact the manufacturer for repair or calibration.

Q: How to store the load box?

A: Store the device in a dry, ventilated area free from corrosive gases. Avoid direct sunlight and moisture. When not in use for an extended period, regularly check the device's condition.

Q: What to do if there is a sudden power outage during use?

A: After power is restored, recheck the device's connections and settings to ensure normal operation. If the device shows any abnormalities, immediately turn off the power and contact a professional for inspection.
