Micsig RCP500 Rogowski AC Current Probe
OVERVIEW
Introduction
The RCP500 Rogowski AC Current Probe measures AC current up to 500A pk, minimum to 200mA pk, with bandwidth ranging from 15Hz to 300KHz, 1% accuracy, and has less than 2mV noise. It adopts the Rogowski coil current measurement system: within the range, the output signal of the system and the current signal to be measured are always linear, so the accuracy will not change with the current; the coil does not contain magnetic saturation components, and no magnetic core and saturation phenomenon, no trouble of heating; the Rogowski coil does not contain ferromagnetic materials and so has no hysteresis effect, the phase difference between the output signal and the current waveform is extremely low, which can be less than 0.8″. The RCP500 is compactly designed with exquisite appearance, suitable for Micsig UPI multi-function probe interface, when used with some Micsig new oscilloscope, no need extra battery or power supply. It can also be used with a Micsig PAO5 adapter to adapt to any other manufacturer’s oscilloscope. The AC current probes can measure current signals with complex inrush currents of power devices, sinusoidal currents of three-p option harmonic components of measured currents, and current measurement.
Safety Precautions
- Measurable circuits should be CAT III 1000V/ CAT IV 600V or below.
- Make sure the BNC terminal is grounded reliably
- Make sure to turn off the circuit under test, before connecting to the probe ring
- Do not use if Rogowski coil or cable sheath is damaged or exposed metal
- Do not use in wet environment
- Do not touch the instrument or the measured object with wet hands
- Please cut off the power after the user.
