Frequently Asked Questions
How much does Fluke 1740 Series repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the unit, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most Fluke 1742, 1746, and 1748 repairs are finished within 5–10 business days of arrival. Expedited turnaround is available when downtime on a study is critical.
Do you still repair the discontinued 1740, 1743, 1744, and 1745?
Yes. These legacy loggers are no longer supported by the manufacturer, but our component-level repair keeps them in service — including display and power faults common on older units.
Can you restore Class A compliance after a repair?
Yes. We verify the measurement functions and GPS time-sync that Class A depends on, and every repair includes NIST-traceable calibration documented against the manufacturer’s published specifications.
Can you fix a unit that lost data or stopped logging mid-deployment?
We repair the cause — storage failures and unstable measurement-circuit power are common reasons a long session fails. Repair restores reliable logging, though we can’t guarantee recovery of data already lost from a failed session.
Do you repair the current probes, Rogowski coils, and CT connectors?
Yes. Corroded or intermittent current-input connectors are a frequent repair, restored and verified so the logger reads accurately again.
What if my exact model or kit isn’t listed?
We service every 1740 Series configuration, including the /B and /EUS versions. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the Fluke 1740 Series?
Electric utilities, power quality consultants, industrial plant engineers, data center operators, and compliance departments rely on these loggers for Class A power quality studies and regulatory verification.
