# Industrial Specification: Ground Continuity Tester

## 1. Technical Definition
A device that verifies the integrity and low resistance of grounding connections in electrical systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1000 Ω resistance measurement range, 1-30 A test current, -20°C to +50°C ambient temperature**. Failure boundary: **Measurement accuracy degradation beyond ±2% of reading ±0.2 Ω, test current deviation &gt;±10% of set value, insulation breakdown at &gt;1000 VAC**, Mechanism: **Ohmic heating exceeding 125°C at test contacts causes material degradation, Hall effect sensor saturation at &gt;100 A·m magnetic fields, dielectric breakdown at &gt;3 kV/mm electric field strength**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
