Rugged Wide Range Digital Igniter Tester

Rugged Design with Safety in Mind

The Valhalla Scientific Model 4314 KV 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.

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

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

The 4314 KV 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 rechargable NiMH (10Ah) pack for portability and line isolation purposes. For added convenience and safety, the 4314 KV feature an internal switching configuration which automatically disables the battery charging circuit when in the operate mode. Alternately, all power is removed from the output circuitry when in the off/charging mode.

As with all Valhalla Digital Ohmmeters and Igniter Testers, the 4314 KV is available with a host of 4-wire probes and cable sets. Check the side column for complete list of Options and Accessories.
