Ultra-Safe Circuitry Meets Rugged Design

The Valhalla Scientific Model 4314 KVS Digital Igniter Tester is designed to provide extremely safe and reliable resistance testing of explosive or volatile devices.  Some of the proven uses include fuses, squibs, igniters, explosive bolts, automobile airbag initiators and many others.

Featuring the ultra-safe inner circuitry of the 4314 Alpha series and the addition of constant current-monitoring, fail-safe check, and 7 ranges, the 4314 KVS packs precision measurement technology into a compact, water-resistant Pelican case for protection in the harshest environments.  The 4314 KV and KVS are impact resistant, water-tight, float in water, are waterproof up to 3-feet when closed, and can operate in direct rain.

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. Countless critical military, aerospace and industrial applications utilize squibs and other blasting devices, and the ability to safely test the explosive’s circuity without accidentally detonating the device is paramount. The 4314 KV and KVS feature redundant, dual fail-safe current limiting network circuitry to ensure the instrument test currents cannot exceed the specified amount, so even in the unlikely event of a worst case component failure, the output current limiting network is still in effect. To prove that this level of safety is intact, the 4314KVS is equipped with a constant test current monitoring display and a unique Fail-Safe test button that simulates a worst-case component failure and displays the “real” fail-safe current, all while the output is isolated from the current source.

Inherently-safe resistance measurement

Essentially, a Model 4314 KVS is a 4-wire ohmmeter which has been designed to use very low test currents for its measurement.  Additional circuitry proprietary to Valhalla Scientific is used to ensure that test current levels do not exceed the specified “failsafe current” even in a worst-case component failure situation.  The failsafe feature is tested in every instrument before shipment and the results provided to the customer on a Certificate of Calibration that accompanies the unit.

In addition, to prove that this level of safety is intact, the 4314 KVS is equipped with a constant test current monitoring display and a unique Fail-Safe test button that simulates a worst-case component failure and displays the “real” fail-safe current, all while the output is isolated from the current source.

Measures Under all Conditions

The 4314 KVS are not only the safest resistance testers for explosive devices, but they are also, thanks to its case, impact resistant and watertight. The devices float in water, are waterproof when closed to a depth of 3 feet, and can be operated outside in direct rain.

They come self-contained with a slim-line AC/DC Battery Charger and measurement test leads ready to use.

The 4314 KVS utilizes a four-wire Kelvin input configuration to eliminate lead wire length and lead contact resistance errors. The units are battery powered with a heavy duty rechargeable NiMH (10Ah) pack for portability and line isolation purposes. For added convenience and safety, the 4314 KVS feature an internal switching configuration which automatically disables the battery charging circuit when in the operating mode. Alternately, all power is removed from the output circuitry when in the off/charging mode.
