Product Detail

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.
