Safety Precautions And User Roles For Keithley 4200A-SCS-PKC High Power I-V & C-V Analyzer.pdf

## Model 4200A-SCS-PKC High Power I-V & C-V Parameter Analyzer: Quick Start Guide Safety Precautions Summary

This guide summarizes critical safety precautions for the Model 4200A-SCS-PKC high power I-V and C-V parameter analyzer.

Target Users:

Responsible Body: Individuals or groups responsible for equipment operation, maintenance, and ensuring safe practices.
Operators: Trained personnel using the instrument; must follow electrical safety procedures and protect against electric shock.
Maintenance Personnel: Responsible for routine maintenance; must refer to user documentation for specific procedures.
Service Personnel: Trained professionals performing installations and repairs; required for direct work on live circuits.

General Safety Principles:

Shock Hazard: Always expect hazardous voltage in unknown circuits before measuring. Operators must be protected from electric shock at all times.
Proper Connections: Avoid connecting to mains voltage unless explicitly allowed in specifications. Use Category II or higher marked instruments if connecting to AC mains.
Isolation: Prevent access and/or insulate operators from every connection point, especially when circuits operate above 1000 V.
Switching Cards: Do not connect directly to unlimited power circuits; use with impedance-limited sources and protect against fault current and voltage.
Power Disconnection: Always disconnect power before connecting or removing cables, switching cards, or making internal changes.

Specific Precautions:

Dry Hands & Insulated Surface: Measurements should be taken with dry hands while standing on a dry, insulated surface.
Instrument Use: Follow operating instructions strictly; exceeding maximum signal levels can cause damage.
Fuses: Replace fuses with the same type and rating for continued protection against fire hazard.
Chassis Connections: Only use for shielding circuits, not as protective earth (ground) connections.
Test Fixtures: Keep lids closed while power is applied to prevent electric shock.
Screws: Securely connect any present screws to ground using recommended wiring.
Symbols:
