Covering a wide 8-measurement range, the 4314-Ki is an ideal fit for the aerospace, defense, renewable energy, and manufacturing industries. The 4314-Ki alone replaces multiple instruments while providing clearer, more useful data for applications involving squib circuits, fuses, release mechanisms, thrust vector motor control, deployment systems, pyrotechnic initiators, primers, and generic circuit continuity testing.
18-Hour Battery Life
With selectable test ranges spanning 2Ω – 20MΩ, the 4314ki is engineered for precision and accuracy across them all.
Dual Power Mode
Certified Mil Std 810 – Method 511
When the front panel power switch is placed in the OFF/CHARGE position, all power is removed from the output terminals, and the battery pack is connected to the charging circuit. When the switch is placed in the ON position, the battery pack is disconnected from the charging circuit.
The possibility of a common mode voltage between the device under test and AC Power ground is therefore. eliminated. The switch also functions as a low battery indicator. When battery level is within operational limits, the switch will illuminate in blue.
The four-terminal configuration of the 4314Ki eliminates errors normally caused by test lead and contact resistances. In many applications, the contact resistance can exceed the value of the load by several orders of magnitude.
The 4314Ki bypasses this potential error source by providing two terminals of constant current and an additional two terminals for high impedance voltage measurement. The result is a fast, accurate resistance measurement of the load, independent of the resistance of the current carrying leads.
As in the past, safety and reliability have been the fundamental focus throughout the conception, prototyping, and testing process. Externally, the unit is housed in a durable, impact-resistant aluminum case built for both laboratory and field use. Internally, the 4314Ki incorporates our redundant fail-safe, current-limiting network circuitry ensuring the instrument test currents cannot exceed the specified amount, even in the unlikely event of a worst-case component failure.
Additionally, the 4314Ki introduces a variety of new features including Dual Power Mode and an Isolated Serial Interface. Dual Power Mode offers the operator either 18 hours of battery life or a 24/7 continuous power mode with the ability to change via a key switch on the rear of the unit. The key switch also acts as an additional safety feature, preventing non-authorized users from changing modes.
The isolated serial interface allows for remote control of the unit through an RS-232 port on the back panel. Digital signals are transmitted across the isolation barrier using iCoupler technology. Via the interface, the user can fully operate the meter and query measurement and configuration data.
