Martindale VI Range: GS38 Compliant Tools for Safe Isolation

Safe Isolation and GS38 Compliant Voltage Indicators

When it comes to electrical testing and maintenance, safe isolation procedures are critical for preventing electrical shock. The Martindale VI range of voltage indicators stands out as one of the few tools on the market that fully meets GS38 compliance. They conform to the requirements of BS EN 61010-1 and are fully compliant with BS EN 61243-3, ensuring both safety and reliability during the essential safe isolation process.

Test Equipment Compliance: Why It Matters

GS38, set by the Health and Safety Executive (HSE), sets strict requirements for tools used in electrical isolation to protect workers from electric shock. While some  voltage indicators may fail to meet these standards, the Martindale VI range ensures compliance by offering enhanced insulation, durable construction, and importantly they have been designed without batteries or switches which could lead to false indication.  Dedicated purely to detect voltage, they eliminate the potential for error from selecting the wrong setting, for example. 

Non-Powered Voltage Indicators: A Key GS38 Requirement

With such a wide range of voltage measuring tools available it is important to identify the correct solution for the safe isolation procedure and, importantly, to understand what should not be used as part of this critical process.

One of the most important aspects of GS38 is the information related to powered voltage. Multimeters and similar products for example can not only introduce the potential for human error – making it too easy to select the wrong range they also rely on battery power; if the batteries are flat then a false “dead” reading will be given on a live circuit.  The position is similar with non-contact voltage detectors; whilst these are frequently used to detect live cables, they cannot reliably be used to prove dead or to confirm the safe isolation of a circuit.

Martindale’s VI range, however, consists of non-powered, self-contained indicators that give immediate, concise results. Reducing the risk of error and helping ensure complete safety during the isolation process.

Why Choose Martindale VI for Safe Isolation?

The Martindale VI Series provide a trusted solution to live voltage indication with no batteries, ranges or switches which could lead to unreliable readings and a heavy-duty design.

Bright LEDs provide instant AC and DC voltage indication at set thresholds. The top of the range VI-15000 indicates voltages up to 690V with a CAT IV 1000V safety rating making it suitable for use in all installation categories.

Other safety features include retractable probes to GS38 specification, heavy duty finger guards and a two-layer double insulated cable with a contrasting inner sheath to easily highlight cable damage which could compromise the user’s safety.

Both models in the range  fully comply with the latest standard for voltage indicators, BS EN 61243-3, which prohibits the use of fuses.  Protection is achieved through a high wattage resistor in the probe that will limit the current at the point of contact in the event of damage to the cable.

The Martindale VI range is designed to withstand harsh working conditions, making them reliable even in challenging environments. These tools are built to last ensuring electricians can trust them day after day. Martindale ensures that safe isolation can be done confidently and securely, without relying on potentially unreliable powered indicators.
