Craftsman Information Device Operation key terms

A portable electronic unit used in the field to capture, store, and transmit work data such as readings, status codes, and completed task records. It typically combines a display, keypad, and communication link in one rugged housing.

An enclosure built to resist dust, water, shock, and vibration so the device survives industrial or outdoor conditions. Its seals and ratings determine where the unit may safely be used and how it must be cleaned.

A two-digit code describing how well an enclosure blocks solid particles and water. The first digit covers dust and the second covers moisture, guiding whether the device may be used in wet, dusty, or washdown areas.

The process of reconciling records held on the device with those held on a central system so both agree. It resolves conflicts, timestamps changes, and confirms which copy is authoritative when the same record was edited twice.

A device state in which data entry and lookup continue using local storage because no network link is available. Records are queued and later uploaded, so operators must know how much local capacity remains.

A completed data entry held locally until a connection is restored and the record can be transmitted. Queues must be monitored because a full queue rejects new entries and can cause lost work.

The specific encoding pattern a barcode uses, such as a linear or two-dimensional format. The scanner and the device must both support the symbology in use, or the label will not decode correctly.

The optical component that illuminates a barcode or tag and converts the reflected light into decoded characters. Its aim pattern, range, and supported symbologies determine what labels it can read reliably.

The proportion of scan attempts that produce a correct decode on the first try. A falling read rate usually points to a dirty window, worn label, poor lighting, or a mismatched symbology setting.

An extra character calculated from the other characters in a code and used to detect entry or scan errors. If the calculated and printed digits disagree, the device rejects the code as invalid.

The first-time setup that prepares a new or reset unit for use, including loading firmware, applying configuration profiles, setting the clock, and enrolling it with the management system. Skipping steps causes later sync and access failures.

A stored set of settings, such as network details, form layouts, and access permissions, that is applied to a device to make it match site standards. Profiles keep fleets consistent and simplify replacement of failed units.

The act of assigning a device to a user, location, or role and granting the correct access rights. Proper provisioning ensures the operator sees only the screens and records their duties require.

Installing a newer version of the low-level software that controls device hardware and core functions. Updates must be applied with a charged battery and stable power, since interruption can leave the unit unusable.

Restoring the previous software version or configuration after an update causes faults. A rollback plan, including a saved copy of the prior settings, should exist before any update is started.

Aligning the device time with an approved reference so that timestamps on records are accurate and comparable. Unsynchronized clocks break audit trails and can make entries appear out of order.

Checking and adjusting a measurement function against a known reference so readings remain within tolerance. Results are recorded with date, reference used, and the person who performed the check.

A document recording that a device was checked against a traceable reference, including results and validity dates. It is the evidence an auditor accepts that measurement data can be trusted.

The permitted range of variation around a target value before a result is treated as out of specification. Operators must know the tolerance for each reading so they can flag exceptions correctly.

A marker applied to a reading that falls outside its allowed range, prompting review or corrective action. The flag must be recorded with the value rather than silently corrected.

The property that recorded information is complete, accurate, consistent, and unaltered except through documented, authorized changes. It depends on controlled access, audit trails, and disciplined entry practice.

A widely used set of expectations for records: attributable, legible, contemporaneous, original, and accurate. Each entry should show who made it, when, and on what basis, without later rewriting.

An automatically maintained log of who created, changed, or deleted a record, with the old and new values and the time. It allows reconstruction of events during review or investigation.

The date and time attached to an entry or change, generated by the system rather than typed by the user. Accurate timestamps establish sequence and support contemporaneous record keeping.

A programmed check that rejects or warns about entries failing defined criteria, such as a range limit or required field. Rules prevent obviously wrong data from entering the record.

Granting permissions according to a user's job function rather than individually, so each person can reach only the functions and records their role requires. It limits accidental and unauthorized changes.

A login method requiring something the user knows plus something they possess, such as a badge or token code. It reduces the risk of access through a shared or guessed password.

An automatic lock that ends an idle login after a set period. It protects records when a device is set down unattended, but operators must save work before the timeout occurs.

A structured record of device status, open tasks, faults, and pending syncs passed from one operator to the next. It prevents duplicated work and ensures known problems are not forgotten between shifts.

An instruction identifying a task, its location, required steps, and expected records. Operators close it only when all required data entries and confirmations are complete.

The final acknowledgment that a step or job was performed as specified, often requiring a signature, code, or scan. It marks the record as complete and locks it against casual editing.

A captured identifier, such as a personal code or biometric, that legally attributes a record to a specific person. It carries the same weight as a handwritten signature and must never be shared.

Routine wiping of the optical window with approved materials to remove dust, oil, and residue. It is the first corrective step when reads become slow or intermittent.

A measure of how much charge a battery can still hold compared with when it was new. Declining health shortens runtime and signals that replacement is due before a shift is affected.

The cradle that supplies power and often the network link for the device. Contacts must be kept clean, and a unit should be seated fully or it will neither charge nor sync.

A written account of a device problem describing symptoms, when it started, what was tried, and the current status. Clear reports speed repair and build a history for spotting recurring failures.

The defined sequence of people or support levels to contact when a fault exceeds the operator's authority or skill. Knowing it prevents prolonged downtime and unauthorized repair attempts.

A safety procedure that isolates energy sources and marks them with a personal lock and tag before maintenance. It ensures equipment cannot be re-energized while someone is working on it.

Items worn to reduce exposure to workplace hazards, such as gloves, eye protection, or hearing protection. It is chosen from the site hazard assessment and inspected before each use.

A documented review of tasks and locations to identify what could cause harm and what controls apply. It determines which procedures and protective equipment are mandatory in each area.
