Protective Fail-Safe Circuitry
9 Test Ranges
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
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
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
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.”
