+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+# 양산형 테스트 기기 모니터링 시스템 사용자 설명서 (User Manual)
+
+  
+
+본 문서는 **양산형 테스트 기기 모니터링 시스템**을 사용하는 작업자 및 검사자를 위한 운영 설명서입니다. 프로그램의 시작부터 제품 조회, 성능 검사 수행, 판정 기준 설정까지 내부 프로그램 코드를 몰라도 누구나 쉽게 작동법을 이해할 수 있도록 사용자 화면 관점에서 기술되었습니다.
+
+  
+
+---
+
+  
+
+## 1. 시스템 개요 (Introduction)
+
+  
+
+본 시스템은 제조 라인의 최종 단계에서 제품의 전기적 성능(측정 전압 및 전류)을 검사하고 최종 합격/불합격 여부를 판정하는 모니터링 프로그램입니다.
+
+- **이전 단계 확인:** 제품의 바코드(S/N)를 조회하여 이전 주요 공정(Housing, Calibration, EOL)을 모두 통과했는지 자동으로 검증합니다.
+
+- **실시간 계측 및 판정:** 검사를 시작하면 전기적 신호가 측정되며, 설정된 범위 이내인 경우 최종 `PASS`(합격), 범위를 벗어나면 `FAIL`(불합격) 판정을 내립니다.
+
+- **파라미터 조율:** 생산 제품 사양에 맞춰 합격 판정 기준 범위(최소/최대 전압 및 전류)를 간편하게 변경할 수 있습니다.
+
+  
+
+---
+
+  
+
+## 2. 전체 동작 흐름도 (Operational Flow)
+
+  
+
+검사자가 프로그램을 구동하여 최종 검사를 완료하기까지의 전체 프로세스는 다음과 같습니다.
+
+  
+
+```mermaid
+graph TD
+    A([1. 프로그램 실행]) --> B[시작 설정 및 로그인 팝업]
+    B --> C{로그인 및 설정 완료?}
+    C -- 취소/종료 --> D([프로그램 종료])
+    C -- 로그인 완료 클릭 --> E[메인 모니터링 화면 기동]
+    E --> F[상단바에서 작업자 및 모델 정보 확인]
+    F --> G[S/N 입력 칸에 바코드 스캔 또는 직접 입력]
+    G --> H[조회 버튼 클릭 또는 엔터 키 입력]
+    H --> I{이전 검사 결과 확인}
+    I -- 이전 단계 중 불합격 존재 --> J[경고 팝업 창 출력 및 진행 불가 표시]
+    J --> K[START 버튼 비활성화 상태 유지 -> 검사 불가]
+    K --> G
+    I -- 이전 단계 모두 합격 PASS --> L[상태: 검사 가능 표시 및 START 버튼 활성화]
+    L --> M[▶ 검사 시작 START 버튼 클릭]
+    M --> N[상태: 검사 진행 중 표시 및 수치 측정 시작]
+    N --> O[전압/전류 계측값이 2초간 흔들리며 측정 동작 연출]
+    O --> P[측정 완료 및 최종값 표시]
+    P --> Q{측정 전압/전류가 기준범위 이내인가?}
+    Q -- 합격 범위 내 --> R[대형 화면에 PASS 녹색 표시 및 합격 판정]
+    Q -- 범위 이탈 --> S[대형 화면에 FAIL 적색 표시 및 불합격 판정]
+    R --> T[시스템 원상 복구 및 다음 제품 검사 대기]
+    S --> T
+    T --> G
+```
+
+  
+
+---
+
+  
+
+## 3. 상세 기능별 동작 가이드
+
+  
+
+### 3.1. 시스템 시작 설정 및 로그인
+
+1. **프로그램 기동:** 프로그램을 켜면 메인 화면이 뜨기 전, **[시스템 시작 설정 & 로그인]** 화면이 화면 중앙에 먼저 나타납니다.
+
+2. **설정값 기입:** 제조사, 모델명, 색상 코드, 라인 번호, LOT 번호, 지그 번호를 확인 및 기입하고, 담당 **작업자명**과 **비밀번호**를 입력합니다.
+
+3. **빠른 테스트 실행 (테스트 계정):**
+
+   - 검사 편의를 위해 작업자(`test`)와 비밀번호(`test`)가 미리 입력되어 있습니다.
+
+   - 별도 수정 없이 곧바로 하단의 **[시스템 시작 및 로그인]** 단추를 누르면 로그인이 완료됩니다.
+
+4. **정보 연동:** 로그인이 완료되면 로그인 창이 닫히고 메인 화면이 자동으로 최대화되어 열립니다. 메인 화면 좌측 상단바 영역에 입력했던 정보가 `[작업자: test | 모델: MOBI-EV-01 | 라인: LINE-3]` 형태로 상시 노출됩니다.
+
+  
+  
+
+---
+
+  
+
+### 3.2. 제품 조회 및 이전 공정 이력 검증
+
+1. **S/N(시리얼 번호) 스캔:** 메인 화면 좌측의 **'S/N 입력'** 상자에 제품 바코드를 스캔하거나 입력합니다. (키보드의 엔터 키 또는 **[조회]** 버튼 클릭)
+
+2. **이전 단계 확인:** 시스템이 이전 공정 단계들의 결과를 불러와 화면 좌측 **'이전 시험 단계 결과'** 표에 표시합니다.
+
+   - **합격 제품 테스트 (S/N: `PASS1234`):** Housing, Calibration, EOL 단계가 모두 초록색 `PASS`로 채워지며, 하단의 대형 **[▶ 검사 시작 (START)]** 버튼이 초록색으로 활성화되어 성능 검사를 수행할 수 있습니다.
+
+   - **불합격 제품 테스트 (S/N: `FAIL5678`):** 이전 단계 중 실패한 항목이 빨간색 `FAIL`로 표시되며, 경고 창이 나타납니다. 하단의 검사 시작 버튼은 비활성화되어 최종 검사 진행이 전면 차단됩니다.
+
+  
+  
+
+---
+
+  
+
+### 3.3. 최종 성능 검사 및 합불 판정
+
+1. **검사 시작:** 초록색으로 활성화된 **[▶ 검사 시작 (START)]** 버튼을 클릭합니다.
+
+2. **측정 중 상태 (2초간):**
+
+   - 검사가 시작되면 상태창이 파란색 **'측정 중'**으로 변경되고 전압 및 전류 측정 영역의 수치들이 약 2초간 측정됩니다.
+
+
+3. **최종 판정:**
+
+   - 2초가 지나면 측정이 끝나고 최종 검출된 전압과 전류 수치가 화면에 고정됩니다.
+
+   - **합격 (`PASS`):** 측정된 전압(디폴트 `4.0V ~ 6.0V`)과 전류(디폴트 `8.0A ~ 10.0A`)가 모두 가이드 범위 내에 도달하면 대형 판정 영역이 초록색 배경의 **`PASS`**로 갱신되며 최종 합격 판정이 완료됩니다.
+
+   - **불합격 (`FAIL`):** 전압이나 전류 중 하나라도 기준 범위를 벗어나면 해당 측정 텍스트와 대형 판정 영역이 빨간색 배경의 **`FAIL`**로 변하여 경보를 나타냅니다.
+
+   - 판정이 종료되면 시스템은 자동으로 대기 상태로 복구되어 다음 제품 검사를 진행할 준비를 마칩니다.

+### 3.4. 판정 기준 파라미터 설정
+
+1. **설정창 열기:** 최하단 바 좌측에 있는 파란색 **[⚙ 파라미터 설정]** 버튼을 클릭합니다.
+
+2. **기준값 수정:** 화면에 팝업창이 나타나며 전압의 최소/최대값 및 전류의 최소/최대 기준 범위를 키보드로 입력하여 수정할 수 있습니다.
+
+3. **유효성 체크 및 저장:**
+
+   - 입력한 값은 음수여서는 안 되며, 최소값이 최대값보다 작아야 저장할 수 있습니다.
+
+   - **[저장]**을 누르면 변경 사항이 적용되며, 메인 화면 전압/전류 카드 하단에 표시되는 가이드 문구(`기준범위: X.XV ~ Y.YV`)가 실시간으로 자동 변경되어 즉시 새로운 판정 기준으로 적용됩니다.
