Fluke 1623 Calibration

Description

Fluke 1623 Earth Ground Tester Calibration and Repair

The Fluke 1623 is an earth ground resistance tester (GEO) — it measures earth/ground electrode resistance using fall-of-potential, selective, and stakeless (clamp) methods for grounding-system verification. Its accuracy depends on the measurement front-end, the stake/clamp inputs, and the reference, which is where service and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 1623 for electrical, utility, and grounding-test teams.

Common Fluke 1623 problems we fix

• Ground-resistance measurement out of spec — the measurement drifting, recalibrated against standards.
• Stake / clamp / input faults — a damaged test input or clamp giving erratic results, repaired.
• A test method not working — fall-of-potential, selective, or stakeless mode failing, repaired.
• Display or interface faults — repaired.
• Won’t power on or hold a charge — battery/power faults.

FAQs

My 1623 ground reading is off — fixable? Yes. Measurement and input faults are repairable, then the tester is recalibrated so ground-resistance readings are accurate, with a NIST-traceable certificate.

Are the methods verified? Yes — measurement is checked against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
