Fluke 43B Calibration
The Fluke 43B is a handheld ScopeMeter, which carries two instruments in one case and needs both calibrated. The oscilloscope side is verified for vertical accuracy and timebase, the meter side for its measurement functions, and they can drift independently of one another.
June Company’s technicians calibrate the Fluke 43B for industrial electricians, field service engineers, and maintenance troubleshooters. Every point is measured against reference standards, with as-found readings recorded before any adjustment and as-left readings afterwards, so you can see what condition the instrument was actually in when it arrived.
What we verify on the Fluke 43B
- Input isolation on the isolated-channel models.
- Vertical amplitude accuracy on each channel and range.
- Timebase accuracy across sweep speeds.
- Bandwidth to the model’s specification.
- Multimeter functions – voltage, current and resistance.
- Trigger level accuracy.
FAQs
How often should this be calibrated? Most quality systems work on an annual interval, though how hard the instrument is used and how critical its readings are should drive that decision rather than the calendar alone.
Do I get as-found data, or only the final result? Both. As-found readings are recorded before any adjustment and as-left afterwards, which is what tells you whether the instrument was in tolerance during the work you already did with it.
Calibration is documented and returned with the instrument. If we find a fault that calibration cannot correct, we quote the repair before going any further. Email us or submit a service request.
