YCRT-C20A Clamp Ground Resistance Tester


Features


  • 4-digit LCD display with black screen design, showing resistance and current synchronously.
  • Jaw size: 55mm×32mm; Meter dimension: 285mm×85mm×58mm; Weight: 1180g (including battery).
  • Power supply: DC 6V (4 AA alkaline dry batteries) with real-time battery voltage display and low battery warning.
  • Data storage: 300 groups of data, with "MEM" indication and "FULL" symbol when full; supports data review ("MR" symbol) and deletion.
  • Overload protection: "OL Ω" (resistance) and "OL A" (current) symbols for over-range overflow.
  • Automatic shutdown: Turns off after 5 minutes of inactivity.
  • Alarm function: Audible alarm and flashing symbol when measured value exceeds set threshold (max alarm setting: 200Ω).
  • Anti-interference: Automatically identifies large interference signals with "NOISE" symbol and prompt sound.
  • Shock-proof, dust-proof, moisture-proof structure.
  • Compliance with safety standards: IEC61010-1 (CAT Ⅲ 300V,CAT IV 150V,Pollution Degree 2), IEC61010-031, IEC61557-1.
  • Fast filtering technology to minimize interference.


Functions


  • Ground resistance test (loop resistance measurement) via clamp method.
  • AC current measurement (range: 0.00mA–20.0A).
  • Data storage/lock/review/delete: Short press "HOLD" to lock/save data, "MEM" to store, "MR" to review, and long press "MEM" to delete.
  • Alarm settings: Customizable thresholds for resistance (> mode), with on/off function via "AL" key.
  • Field application methods:
    • Multi-point grounding system: Measures loop resistance in parallel grounding networks.
    • Limited point grounding system: Solves nonlinear equations for N grounding bodies (requires optional software).
    • Single-point grounding system: Uses two-point or three-point method with auxiliary grounding bodies to create test loops.
  • Self-calibration: Automatic calibration on power-up; displays "Er" for startup errors (e.g., open jaws).
  • Interference detection: Alerts with "NOISE" symbol and sound when high interference is detected.
