eFX6000 – Wide Range Flexible Current Probe

The eFX6000 wide range flexible current probe is the single best choice for all around AC current measurement.

Flexible probes are powered from the PowerSight meter – no external batteries are needed.

Note: eFX6000 is not compatible with the discontinued PS3000, PS4000, & PS250 analyzers.

Summary | Features | Specifications | Documents | Recommended Products

The EFX6000 is a flexible AC current clamp utilizing the Rogowski principle. It can be used to measure currents from 1 amp to 6000 Amps in 2 auto-ranges, over a wide frequency range to 10kHz. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas, around large conductors and where access to confined or tight spaces is a problem. It requires no batteries or external power supply.

Features

Wide measurement range makes it the best single choice for a current probe: 1 – 6,000 amps AC.

Flexible rope-type technology allows use in tight spaces where clamp-ons cannot fit.

Thin enough (0.4″) to thread between tight conductors and long enough (24″) to wrap around multiple conductors and bus bars.

Lighter weight than clamp-on style probes.

36″ long ropes are also available for wrapping large groups of cables.

No batteries or power supply are required. The probes are powered by the analyzer so there is no chance of a current probe dying while a power study is underway.

Dual range to provide the best accuracy and resolution.

Full auto-ranging with the PS3500. For the PS4500, the user is notified of the range on the meter’s display, allowing the user to set the range directly from the analyzer’s keypad. This eliminates the errors of forgetting to set the range switch correctly on each probe or of the switch of one of the probes getting changed accidentally. If the user sets the range to the low range, but the conditions change during monitoring, it will auto-range to the higher range to maintain accuracy in the logged data.

Probes are calibrated at the “9 o’clock position” (see slide above) to simulate the most realistic use in the field. This allows achieving better accuracy than other suppliers’ ropes do, 1% when mounted as calibrated (2% independent of position).
