11.2 Test Data Recording, Field Forms, and Data Integrity

Test Data Recording, Field Forms, and Data Integrity

Quick Answer: Level II task 2.4.2 requires the technician to "accurately record nameplate and other pertinent test data," with the graded skills including "recognize which test data shall be recorded" and "accurately record test results." The 2026 Level II outline restates it as 2.3.2, "Record test data." The single principle: a measurement without its conditions is not data — it is a number that cannot be corrected, compared, or trended.

1. What must be recorded on every test

Temperature is the item most often omitted and most often needed. Insulation resistance, power factor, winding resistance, and battery specific gravity all require temperature correction. A record without a temperature can never be normalized, which means it can never be compared to next year's reading. In trending terms, that test was wasted effort — the technician did the work and produced nothing durable.

Load current matters for the same reason on energized tests. A thermographic ΔT or an operating measurement taken at unknown load cannot be projected to service conditions.

2. As-found and as-left

Whenever anything is adjusted, both states are recorded.

• As-found is what the equipment was actually doing before you touched it. It is the only evidence of whether the device had drifted, had been mis-set, or had been left on test settings by someone else. It is also the data that reveals a genuine maintenance problem rather than a one-off.
• As-left is the state the equipment is in now, and it is what the next technician, the coordination study, and the arc flash label depend on.

The as-found value is the more valuable of the two for engineering purposes, and it is the one most often skipped because the technician is focused on getting the setting right. A relay found 40 % off its setting and quietly corrected leaves no record that anything was ever wrong; the same relay recorded as-found tells the owner they have a drift problem across a population of similar relays.

Applies to: relay settings, trip unit settings, tap positions, timer and pressure switch settings, transformer tap position, and any adjustment made during commissioning.

3. Photographs

• Nameplates. A photograph is more reliable than a transcription and settles later disputes. A transposed digit in percent impedance propagates through the short-circuit study, the coordination study, and every arc flash label downstream.
• As-found conditions, particularly anything abnormal: damage, contamination, a wrong component, an unexpected connection.
• Deficiencies — a thermogram without a matching visible-light photograph rarely lets a repair crew identify which of six identical lugs is the problem.
• Test setups for unusual or contested measurements, so the connection can be reproduced.
• Restoration — grounds removed, links landed, covers on. This is genuinely useful evidence when a question arises later about whether something was left in place.

4. Plotting and presentation

Level II task 2.4.3 requires the technician to "plot graphs of data from tests performed by Level II technicians," with knowledge of scales and skills in selecting appropriate scales, translating measurement units, and plotting and labelling points.

• Choose the scale to reveal the data, not to flatter it. A trend plotted on a scale that compresses a 60 % decline into a visually flat line has misrepresented the finding — and doing so knowingly touches the Code of Ethics clause about not distorting facts.
• Logarithmic scales are standard for time-current curves and are often appropriate for insulation resistance, which spans orders of magnitude.
• Label every axis with units and state the correction basis, for example "insulation resistance, MΩ, corrected to 20 °C."
• Plot the criterion line — the manufacturer's minimum or the applicable table value — on the same chart, so the reader sees the margin, not just the value.
• Plot all three phases together. The phase-to-phase divergence is usually the finding, and separate charts hide it.

5. Data integrity

A test record is a legal and contractual document. It supports acceptance of a construction project, evidences compliance with maintenance obligations, and will be produced in any investigation or litigation following a failure. That status carries obligations:

• Record what you measured, not what you expected. An unexpected result is information, and it is the whole reason the test was performed.
• Do not "clean up" data. Rounding to a nicer number, discarding an outlier because it seemed wrong, or averaging away a discrepancy all destroy the finding.
• Corrections are made transparently. If an entry is wrong, strike it so it remains readable, enter the correct value, and initial and date the change. Erasing or overwriting destroys the audit trail and looks like concealment even when it was innocent.
• Never sign for work you did not perform or witness. NICET's Code of Ethics requires certificants to "perform their duties in an efficient and competent manner with fidelity and honesty" and to "not misrepresent... their degree of responsibility for any work."
• Do not alter a record after the fact to match an expected outcome. The Code requires certificants to "admit and accept their own errors when proven wrong and never distort nor alter the facts in an attempt to justify their decisions."

Incomplete tests are recorded as incomplete. If access was denied, a component could not be isolated, or an outage window closed early, the report says so explicitly and identifies what was not tested. A report that is silent about an untested item implies it was tested and passed — which is a misrepresentation by omission and, if a failure later occurs there, an indefensible one.

6. Accident and incident reporting

Level II task 2.4.5 requires the technician to "report accidents," with the knowledge item being the OSHA accident report form and the skill "provide data for an OSHA-required accident report form."

Practical obligations:

• Report every incident, including near misses. A near miss is a free lesson.
• Provide factual data — what happened, when, where, who, what equipment, what conditions. Not speculation about fault.
• Preserve the scene where the incident involved equipment, for the same reasons that apply to a failure investigation.
• Understand that OSHA has specific reporting timeframes for serious events — fatalities and certain hospitalizations, amputations, and eye losses must be reported to OSHA within defined short windows, and the employer maintains the injury and illness log.
• Cooperate fully with the employer's and OSHA's investigation.

Exam trap: A question describes a technician who realizes an entry on a completed test form is wrong and asks how to correct it. Erasing, overwriting, or replacing the page destroys the audit trail. The correct method is to strike the entry so it remains legible, enter the correct value, and initial and date the change.
