Fluke 302 Calibration
The Fluke 302 is a clamp meter, which is calibrated differently from a bench instrument because the measurement depends on a magnetic circuit. Jaw alignment, jaw wear and where the conductor sits inside the opening all affect the reading, so verification has to account for the jaws and not only the electronics behind them.
June Company calibrates the Fluke 302 for electricians, industrial maintenance teams, HVAC technicians, and energy auditors. 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 302
- Inrush and peak capture where fitted.
- Frequency and power measurement on the advanced models.
- AC current across all ranges, at several positions in the jaw.
- DC current on models with Hall-effect sensing.
- Jaw alignment and closure – a gap or a worn mating face changes the reading before any electronics are involved.
- Voltage and resistance functions where fitted.
FAQs
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.
What happens if it comes back out of tolerance? We record the as-found condition and tell you, because measurements you took with it since its last calibration may need reviewing. That is the reason as-found data matters.
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.
