Fluke 99B ScopeMeter Repair
The Fluke 99B is a classic dual-channel portable ScopeMeter — a rugged handheld combining oscilloscope and multimeter functions for field troubleshooting in industrial and automotive environments. As an older field-carried instrument, its faults concentrate in the input front-ends, the display, and the battery/power section.
June Company repairs and calibrates the Fluke 99B for industrial electricians and field-service technicians.
Common Fluke 99B problems we fix
- A channel dead, noisy, or inaccurate — input front-end damage, often from an over-range input, repaired and recalibrated.
- Display failure — blank, dim, or degraded LCD, repaired.
- Won’t power on or hold a charge — battery and power-section faults, serviced.
- Bandwidth or vertical accuracy off — front-end drift, recalibrated.
- Input/connector faults.
FAQs
It’s an older 99B — still repairable? Yes. These are rugged and serviceable; a repair keeps a proven field tool running for far less than replacement, with input and display faults the usual fixes.
Can you still calibrate it? Yes — vertical accuracy and bandwidth are recalibrated against our standards with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
