Reduced-Current Digital Ingiter Tester
Those working with explosive devices can have peace of mind with the Alpha 4314 KRC’s redundant fail-safe limiting circuitry that physically prohibits accidental ignition in the event of equipment failure.
7 Test Ranges
Select 4 of 7 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 KRC’s 4-wire Kelvin inputs.
Portable or AC Power
Option AC-115 replaces the battery functionality with continuous isolated AC power.
The Alpha 4314 KRC 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 KRC to communicate data with other devices.
Ranges, Resolution, and Accuracy
While standard version of the Alpha 4314 KRC features 20, 200, 2k, and 20k Ohm ranges, it can be configured to meet your needs. The table below lists the nine possible ranges that can be installed in the Alpha 4314 KRC. When ordering, simply specify the four range numbers you want to be installed in your instrument. The 20MΩ and 100MΩ ranges are only available on the standard current configuration.

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 KRC 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.
For applications requiring data output the Alpha 4314 KRC is available with “BCD.” Notice that the BCD Option does not interfere or change the FailSafe feature of the instrument.
AC-115 Continuous Isolated AC Power
Replaces battery pack functionality with continuous isolated AC power.
