# Documentation: DTS.Common.Classes.Sensors.AnalogDiagnostics

## 1. Purpose

This module provides entity classes for analog sensor diagnostics within the DTS system. It models diagnostic test runs and individual diagnostic measurements, serving as data transfer objects that map directly to database records. The classes support both programmatic instantiation and hydration from SQL query results via `SqlDataReader`, facilitating the persistence and retrieval of sensor diagnostic data such as excitation, offset, noise, and shunt measurements.

## 2. Public Interface

### DiagnosticRun Class

**Namespace:** `DTS.Common.Classes.Sensors.AnalogDiagnostics`  
**Implements:** `IDiagnosticRun`

Represents a diagnostic test run session.

#### Constructors

| Signature | Description |
|-----------|-------------|
| `DiagnosticRun()` | Default parameterless constructor. |
| `DiagnosticRun(SqlDataReader reader)` | Constructs an instance by reading column values from the provided `SqlDataReader`. Checks for `DBNull.Value` before casting each field. |

#### Properties

| Property | Type | Default | Description |
|----------|------|---------|-------------|
| `Id` | `long?` | `null` | Unique identifier for the diagnostic run. |
| `DataPROUser` | `string` | `string.Empty` | User identifier associated with the run. |
| `TestId` | `int?` | `null` | Identifier for the test being executed. |
| `TestName` | `string` | `string.Empty` | Human-readable name of the test. |
| `PreTest` | `bool` | `true` | Indicates whether this is a pre-test diagnostic run. |

### DiagnosticEntry Class

**Namespace:** `DTS.Common.Classes.Sensors.AnalogDiagnostics`  
**Implements:** `IDiagnosticEntry`

Represents a single diagnostic measurement entry within a `DiagnosticRun`, containing sensor channel information and multiple diagnostic measurements with their statuses.

#### Constructors
