Find the cause of difficult problems
The 376 FC clamp meter uses an integrated low-pass filter for accurate measurements of non-linear signals, such as adjustable speed drives, electronic ballasts and other non-linear loads. The clamp also uses proprietary inrush measurement technology to filter out noise and capture motor starting current exactly as the circuit protection sees it.
Measure:
- Voltage to 1000 V AC or DC
- Resistance to 60 kΩ with continuity detection
- Min, max, average, and inrush recording to capture variations automatically
- 500 mV DC measurement range to interface with other accessories
- 1000 μF capacitance measurement
Work safely and conveniently
The 376 FC clamp carries a CAT III 1000 V, CAT IV 600 V safety rating, designed to offer you the highest possible protection in a test tool.
The included iFlex flexible current probe provides easier access to large conductors in tight spaces. The flexible probe:
- Expands the measurement range to 2500 A AC
- Allows frequency measurement to 500 Hz with body jaw and iFlex
