Ultra-Safe Resistance Measurement for Explosive Devices

1
The clear LED display makes reading test values fast and uncomplicated.
2
The 4-wire Kelvin connection prevents lead wire length and contact resistance errors.
3
The battery indicator light illuminates when the heavy duty rechargeable NiMH batteries need recharging. Battery charger included.

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.

Even in the unlikely event of a worst case component failure, the output current limiting network is still in effect.

Accurate, Portable Precision

The Alpha 4314 KRC 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. An AC adaptor battery charger is standard. For added convenience and safety, the Alpha 4314 KRC 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 Alpha 4314 KRC is available with a host of 4-wire probes and cable sets. Consult the end of this section for complete information on Options and Accessories.

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).

Options RS232 This option provides a safety isolated RS232 Serial interface. The interface provides measurements and other information.
BCD This option provides parallel BCD data on p rear-panel 50-pin connector. All outputs are TTL comparable levels with a drive capability of 1 LS load.
AC-115 Continuous Isolated AC Power
AF-6 A 6-pin Mil-Spec circular connector (MS3112E10-6S) replaces the four-terminal banana jacks and the battery charger jack. Makes it physically impossible to simultaneously connect the AC/DC Charger while measuring with the test leads.

Available Interface Options

RS-232 Serial Interface Capability (NEW)

The interface is isolated to 2.5kV on both power and Data lines and uses iCoupler Technology. Option RS-232 provides a safe way to communicate with the Alpha 4314 via a computer or PLC and allows the transfer of single readings or continuous transmission of data. This interface is for data acquisition only and does not provide range control. See Datasheet for more details.

AC-115 Continuous Isolated AC Power

Replaces battery pack functionality with continuous isolated AC power.

BCD Capability

For applications requiring data output the Alpha 4314 is available with “BCD.”  Notice that the BCD Option does not interfere or change the FailSafe feature of the instrument.

AF-6

A 6-pin Mil-SPec circular connector replaces the four-terminal banana jacks and the battery charger jack.  Makes it physically impossible to simultaneously connect the AC/DC charger while measuring with the test leads.
