Frequently Asked Questions
Do you still repair the discontinued Fluke 430 Series?
Yes. The 430 Series is replaced by the 1770 Series, but we repair and recalibrate all 430 models — 434, 435, 437, 438 and their -II versions, plus the legacy 43B — which remain heavily deployed.
How much does Fluke 430 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 434, 435, 437, and 438 repairs are finished within 5–10 business days of arrival, with expedited turnaround available when downtime on a study is critical.
Can you restore Class A compliance after a repair?
Yes. We verify the measurement functions that IEC 61000-4-30 Class A depends on, and every repair includes NIST-traceable calibration documented against Fluke’s published specifications.
Do you repair the 437-II 400 Hz and 438-II motor-analysis functions?
Yes. We service the 400 Hz aviation/military capability on the 437-II and the motor-analysis functions (torque, speed, efficiency) on the 438-II, restoring and verifying those measurements specifically.
My analyzer won’t store data or download — can you fix it?
Yes. SD card slot failures and USB download faults are common 430 Series repairs, traced and restored so you can save and offload your measurements again.
What if my exact model isn’t listed?
We service every 430 Series configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the Fluke 430 Series?
Facility electricians, power quality consultants, utilities, aviation maintenance teams (437-II), and motor-driven equipment operators (438-II) rely on the 430 Series for three-phase power quality and energy analysis.
