Advanced Digital Electrical Diagnostics: MESTEK ST06 GFCI Outlet Tester With Colorful Screen in Malaysia

For building inspectors, certified electricians, facility engineers, home safety auditors, and maintenance contractors across Malaysia, accurate electrical receptacle diagnostics require clear, real-time feedback. MTM Precision is proud to present the MESTEK ST06 GFCI Outlet Tester With Colorful Screen—a premium digital socket testing instrument engineered with a high-definition VA reverse display color screen and real-time AC voltage measuring capabilities.

Certified with official Intertek ETL (cETLus) safety marks and rated to CAT II 135V 50/60Hz compliance, the MESTEK ST06 replaces conventional LED light indicators with a rich digital color interface that directly displays circuit voltage, trip response times, and text-based wiring fault diagnoses.

🌟 Key Features & Advanced Capabilities

High-Definition VA Reverse Display Color Screen: Features a high-contrast VA color screen that displays numerical AC voltage values, active test modes, trip parameters, and clear text diagnostics readable under direct sunlight or in pitch-black environments.
Real-Time AC Voltage Measurement: Directly reads and displays the operational line voltage (VAC) of the socket under test, allowing quick verification of voltage drops, brownouts, or over-voltage conditions.
7-Pattern Detailed Wiring Diagnostic Matrix: Evaluates 7 distinct wiring states with clear textual feedback on the screen:
- CORRECT: Wiring is fully correct and properly grounded.
- OPEN NEU: Neutral wire is disconnected or open.
- OPEN GRD: Earth ground wire is disconnected or open.
- HOT/GRD REV: Live/Hot wire and Earth Ground wire are wired in reverse.
- HOT/NEU REV: Live/Hot wire and Neutral wire are wired in reverse.
- OPEN HOT: Live/Hot wire is disconnected or de-energized.
- OPEN GRD NEU: Both Earth Ground wire and Neutral wire are open/disconnected simultaneously.
One-Touch GFCI Leakage Trip Testing: Integrated GFCI test button simulates earth leakage currents to test Ground Fault Circuit Interrupter (GFCI) breakers, recording trip status and safety response.
Dual Alarm System (Screen & LED Indicators): Combines clear text prompts on the color screen with red (FAULT) and green (CORRECT) dual bottom LED lamps for immediate visual confirmation.
Smart Battery Management: Powered by 2 x 1.5V AAA batteries with an automated power-off feature after 3 minutes of inactivity to conserve battery life.
