Overview

The iTest Pro ST007 is a professional electrical socket tester designed to verify the wiring of electrical sockets and the functionality of Residual Current Devices (RCDs) within a wiring system. Engineered in Germany, this plug-in device is specifically designed for 16A sockets.

Function Description

The primary function of the ST007 is to test the socket wiring and provide clear indications of any faults. It identifies various wiring errors, including:

• Correct Wiring: Indicates that the Earth (PE), Neutral (N), and Live (L) connections are all present and correctly wired, with no reversals between Live and Neutral, or Live and Earth.
• Missing Earth (PE): Lights up when the Earth connection is absent.
• Missing Neutral (N): Lights up when the Neutral connection is absent.
• Missing Live (L): Lights up when the Live connection is absent.
• Live Neutral Reverse: Indicates that the Live and Neutral wires are swapped.
• Live Earth Reverse: Indicates that the Live and Earth wires are swapped.

Beyond basic wiring checks, the ST007 also assesses the presence and operational quality of an RCD in the wiring system. It performs both automatic and manual tests. The automatic test routine examines the socket for 5 seconds and displays the initial test result. For more detailed analysis, the device offers a Neutral (N) / Earth (PE) Reversal Test and a Manual RCD Test.

It's important to note that while the ST007 is comprehensive in its wiring and RCD checks, it does not check the earth loop impedance, which is a necessary test that requires a separate Loop tester device.

Important Technical Specifications

• Operating Voltage & Frequency: 230VAC 50Hz
• Temperature Range: -15°C to 45°C
• Dimensions: 60mm x 50mm x 50mm
• Weight: Approximately 0.1kg
• Power Supply: From mains
• Power Consumption: < 0.25W
• Overvoltage Category: Cat II / 300 V
• Pollution Degree: 2
• Warranty: 3 years
• Safety Compliance: Complies with EN 61010-1, EN 61326-1

Usage Features

The ST007 is designed for ease of use, featuring a clear LED indicator system for displaying test results.

• Automatic Tests: Upon plugging the ST007 into a socket, it automatically initiates a test routine, providing immediate feedback on the socket's polarity.
• Manual Tests:
  • Neutral (N) / Earth (PE) Reversal Test: This test is performed by pressing the "N ~ PE" button. The device can detect Neutral-Earth reversal only if an RCD device is present and creates a current leakage higher than 30mA between Live (L) and Neutral (N).
  • RCD Testing: The RCD test is initiated by pressing the "RCD" button (marked with "30mA"). A correct result means the RCD will not be tripped, while a fail result indicates the RCD will be tripped. A critical warning states that if no RCD is present or if it's damaged, the ST007 might incorrectly consider the test as correct.
• LED Indicators: The device utilizes three LEDs to clearly indicate various wiring faults and test statuses.
• Safety Precautions: Users are advised to always verify the product's condition before use, ensuring it's free from defects, dust, grease, and moisture. It should not be used if damaged. The ST007 should be operated by skilled personnel who understand the implications of electrical testing. It is also recommended to test the ST007 in a known correctly wired socket before use to confirm its good working condition. The device should not be used at main incoming distribution boards or across two phases of a three-phase supply, nor will it correctly test circuits using isolation transformers.

Maintenance Features

To ensure a long product life and accurate operation, the following maintenance practices are recommended:

• Preserve Long Product Life: The ST007 should be unplugged from the socket after each test and not left plugged in for extended periods.
• Calibration: iTest Pro recommends returning the ST007 to an approved Calibration Laboratory at least once a year for recalibration and certification to maintain measurement accuracy. Calibration services are offered by iTest Pro.
• Cleaning: The device can be cleaned with a soft, dry cloth. Moisture, abrasive materials, solvents, or conductive detergents should not be used.
• Repair & Service: The unit contains no user-serviceable spare parts. For any damage or defects beyond the warranty period, customers should contact the customer service department for repair quotes.
• Storage Conditions: To prolong its lifespan, the product should be stored in dry conditions, away from heat or direct sunlight. It should be kept in its supplied case and not stored in a toolbox alongside other tools where it could be damaged.

The iTest Pro ST007 is a reliable and essential tool for electricians and professionals needing to quickly and accurately assess the safety and correctness of electrical socket wiring and RCD functionality.
