General Information
Instrument Description
Welcome to a new era of Protection. Featuring the intrinsically safe internal circuitry of our storied 4314
Igniter Tester line, the 4314Ki begins the next generation of precision measurement instruments.
Covering a wide 8-measurement range, the 4314Ki is an ideal fit for the aerospace, defense, renewable
energy, and manufacturing industries. This unit can easily replace multiple other instruments while
providing clearer, more useful data. Some applications include squib circuits, fuses, release mechanisms,
thrust vector motor control, deployment systems, pyrotechnic initiators, primers, and generic circuity
continuity testing.
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 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 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.
Please read this manual thoroughly and all accompanying addendums before attempting to operate this
ohmmeter.
Instrument Identification
Valhalla Scientific instruments are identified by a two-part serial number. The Serial Tag is located on the
rear or bottom of the instrument. The number is in a form of 67-0000. The first two digits, called the serial
number prefix, indicate the model. It changes only when a change is made to the instrument. The last 4
digits, called the serial number suffix, are unique for each individual unit.
Be sure to include the entire serial number, both prefix and suffix, in any correspondence about your
instrument.
Safety Precautions
For an increased level of safety, plug the 4314Ki to a power source only while charging the batteries or
in Continuous Power Mode.
Do not switch between power modes while the device is powered on.
