Exhibition compliment
Canton Fair Venue
Our primary product at the Canton Fair was our ultra-low frequency tester. It attracted numerous inquiries from clients on-site, with some immediately recognizing that both the price and performance met their company's requirements and placing pre-orders on the spot.
Maintenance
1. After Every Use (Daily/Before & After each test)
LOOK for damage: Inspect cables, connectors, and the case for cuts, cracks, or burns.
CLEAN everything: Wipe down the unit, cables, and connectors with a clean, dry cloth to remove dust and moisture. Keep it spotless.
CHECK the ground cable: Ensure the grounding wire and clamp are in perfect condition. This is your primary safety device.
2. Periodic Checks (e.g., Monthly or Quarterly)
CHECK your accessories: Verify that your safety gloves, voltage detector, and grounding stick are still certified and undamaged.
TEST the self-test: Many units have a built-in self-test or calibration check function. Run it to verify the electronics are healthy.
STORE properly: Keep the tester in its original case in a dry, temperature-controlled room. Avoid leaving it in a hot van or damp warehouse.
3. Once a Year (or as per manufacturer)
CALIBRATEATE:This is the most important professional service. Send the entire system (tank, console, cables) to a certified lab or the manufacturer for annual calibration. This ensures your 40kV readings are accurate and your test results are valid.
What to AVOID (Simple Don'ts)
DON'Tyank cables by the wire-always pull by the connector.
DON'Toperate with damaged parts. Replace them immediately.
DON'Tskip the grounding step. Ever.
DON'Texpose the unit to rain or store it in a damp place.
