Profile:

A compact, lightweight tester integrating 3-terminal and 4-terminal measurement. It uses DC/AC conversion technology and large-scale integrated circuits, replacing manual hand-cranking with low-frequency constant current, ensuring high accuracy and user-friendly operation.

Features:

  1. Integrates 3-terminal and 4-terminal measurement modes into one unit for versatile use.
  2. DC/AC conversion generates low-frequency constant current, eliminating manual hand-cranking.
  3. PLL synchronous tracking detection and switched-capacitor filter ensure strong anti-interference performance.
  4. No manual balance adjustment required; 3.5-digit LCD display for clear, intuitive reading.
  5. Multi-functional: measures ground resistance, soil resistivity, low-resistance conductors and AC ground voltage.
  6. Aluminum alloy case for durability; overload displays "1" conforming to common measurement habits.

Parameter:

  1. Operating conditions: Temperature 0℃~+45℃; Relative humidity ≤85%RH
  2. Measurement range & constant current (RMS): Resistance: 0~2Ω (10mA), 2~20Ω (10mA), 20~200Ω (1mA); Voltage: AC 0~30V

  4. Measurement error caused by ground voltage: ≤±5% (allowable ground voltage ≤5V RMS, power frequency)
  5. Power supply & power consumption: Maximum power loss ≤2W; Power supply: 6.8V~9V (7 AA rechargeable batteries); external AC 220V for charging
  6. Dimensions (L×W×H): 220mm×200mm×105mm
  7. Weight: ≤1.4kg
