Protective Fail-Safe Circuitry

Those working with explosive devices can have peace of mind with the Alpha 4314’s redundant fail-safe limiting circuitry that physically prohibits accidental ignition in the event of equipment failure.

9 Test Ranges

Select 4 of 9 test ranges when you order, giving you the ultimate in flexibility no matter what your application

4-Wire Kelvin Inputs

Never worry about lead wire length or contact resistance errors requiring redundant calculations with the Alpha 4314’s 4-wire Kelvin inputs.

Battery-Powered Portability

The Alpha 4314 is powered by high-capacity rechargeable batteries, enabling true portability and enhancing intrinsic safety. Continuous isolated AC power is available as an alternative (Option AC-115).

US Military-Approved

US Military-Approved
The Alpha 4314 has been approved by the Department of Defense and all branches of the armed services, including special projects use (i.e. Cruise Missle).

Export Data to PC/Printer/Recorder

You can configure your instrument with a BCD or RS-232 interface which enables the Alpha 4314 to communicate data with other devices.

 

Designed with Fail-Safe Circuitry

Countless critical military, aerospace, and industrial applications utilize squibs and other blasting agents, and it is vital that these devices detonate precisely when required – not sooner, not later, not while testing for continuity integrity.  To guarantee both the readiness of the device and the safety of the technician or engineer, the Alpha 4314 is equipped with redundant, dual fail-safe, current-limiting network circuitry that ensures instrument test currents cannot exceed the specified amount.

To certify that this level of safety is included in your instrument, we simulate a worst-case component failure during final testing and include the resulting recorded output current flow with your order.

Government and Military Approved

The 4314 series’ circuitry has been reviewed and approved by a U.S. Government Safety Board and all branches of our armed forces for specific military programs (i.e. Cruise Missile).

EWR Drop Test Compliant

Compliant To The Eastern And Western Range (Ewr) 127-1 Range Safety Requirements For Drop Test, including that “These devices shall be analyzed to verify that rough handling, dropping, or single component failure will not result in negating the current-limiting feature.”

Safe for Explosive and Volatile Atmospheres

The Alpha 4314 offers unmatched safety while delivering uncompromising performance and has passed rigorous testing to achieve its status as “Certified Mil Std 810 – Method 511 Safe for Explosive & Volatile Atmospheres.”
