Megger MTB7671/2 Instrument test box

Description

Comprehensive Instrument Verification for Reliable Testing

The Megger MTB7671/2 Instrument Test Box is ingeniously designed to verify the full operational spectrum of electrical testers, ensuring accuracy, reliability, and sustained calibration between professional checks. This versatile test box delivers essential confirmation that testers continuously operate within regulated parameters, covering vital functions such as insulation, continuity, loop, prospective fault current (PFC), residual current device (RCD), and voltage measurements. By facilitating these comprehensive assurance tests, the MTB7671/2 empowers electrical contractors, inspectors, laboratory personnel, and facility managers to maintain compliance with stringent industry standards like BS7671, BS EN 61557, and guidelines from the IEE On-Site Guide. The confirmation provided by the MTB7671/2 is increasingly required by certifying bodies such as NICEIC, ELECSA, and Corgi, who now request demonstrable evidence supporting tester accuracy and reliability.

Advanced Compliance with International Standards Requirements

Meeting and exceeding the requirements of today’s safety and installation practices, the Megger MTB7671/2 Instrument Test Box is engineered to test not merely the basic operational status, but also verifies that testers employ the correct current and voltage settings for each function. For instance, in continuity testing, the test box ensures the tester produces a short-circuit current greater than 200 mA and an open-circuit voltage within the 4 to 24 V range—vital thresholds for accurate and regulatory-compliant testing. Every test performed is accompanied by intuitive pass/fail indications, set in accordance with published technical specifications for each test parameter, guaranteeing that your instruments are never out of compliance. These rigorous controls ensure both safety and precision in all electrical installations.

Exclusive Features for Assured Performance Verification

A standout attribute of the MTB7671/2 lies in its capacity to confirm that not only are measurements being made, but the underlying electrical parameters are true to specification. Unique to this test box is its capacity to simulate real-world load conditions and verify continuity, insulation, loop, RCD, PFC, and voltage measurements through precisely defined reference values. For insulation testers, it checks output voltage points (250 V, 500 V, and 1 kV) and confirms the correct current (over 1 mA) at reference loads such as 9 MΩ and 90 MΩ. Continuity tester validation involves ensuring correct open-circuit voltages and short-circuit currents with resistance checkpoints at 0.5 Ω and 5 Ω. The systematic approach elevates the assurance level well beyond simple functional checks, catering critically to professionals who must document and uphold consistently high standards in calibration records.

Tailored Applications in Electrical Safety Verification

Exclusively, the Megger MTB7671/2 Instrument Test Box is vital for organizations performing frequent electrical safety verification, preventive maintenance routines, or compliance audits. It is exceptionally suitable for calibration laboratories, field service engineers, industrial maintenance teams, electrical contractors, and institutions with periodic tester verification protocols. For installations protected by RCDs, the MTB7671/2 is ingeniously designed to perform all required tests without inadvertently tripping circuit protections, a crucial advantage in modern electrical environments. The device also features color-coded functions, providing at-a-glance guidance for each test type, streamlining workflow, and minimizing errors. By confirming the accuracy and proper functioning of testers before and between formal calibrations, it prevents errors from propagating through critical safety testing and documentation processes.

Focused on RCD, Loop, and Voltage Measurement

Recognizing the evolving needs of the industry, the MTB7671/2’s specialized features further enhance safety and regulatory adherence. For RCD testing, it caters to critical fault current values (10 mA, 30 mA, 100 mA) and supports all standard tests including half (1/2I), nominal (I) at 0° and 180°, and high current (5I) at both phases. The distinctive arrangement of dedicated LED indicators provides real-time feedback through ‘trip’ and ‘5I’ signals, simplifying evaluation procedures and reducing the chance of oversight. Loop testing features are equally advanced; the box enables direct loop measurement from a standard outlet, offers selectable loads for TT system simulation (loop, loop + 10 Ω, loop + 180 Ω), and a dedicated PFC check. The inclusion of a 230 V output terminal supports quick, accurate checks of voltage ranges in measuring instruments.

Assured Safety, Durability, and Environmental Robustness

The Megger MTB7671/2 Instrument Test Box places safety, durability, and reliability at the forefront of its design philosophy. Fully compliant with IEC61010-1 (safety) and IEC 61326-1 (EMC), the test box comes protected by a 30 mA RCD plug, making it safe to use even on RCD-protected mains supplies. This safeguard means even a faulty tester cannot create a hazardous environment. Its robust construction (320 x 280 x 100 mm; weight 2.2 kg) ensures stability during frequent use and transportation. Designed for real-world working environments, it operates reliably from 0°C to 40°C in up to 85% humidity, and can be safely stored in a much wider temperature range. The low power consumption (10 VA at 230 V, 50 Hz) and replaceable fuses ensure both convenience and operational longevity.
