Model No. (Order Code)
Note: These products cannot be used alone. The optional SENSOR UNIT is required in order to supply power and connect the clamp to a Memory HiCorder or other instrument. Products can be directly connected to the compatible Power Meters and Power Analyzers. |
High-accuracy current sensors ideal for use with oscilloscopes and power meters Compared to current sensors that use Hall elements, flux gate type current sensors are not prone to measurement error caused by variations in the external temperature. In addition, they can measure extremely low input (current values) and current waveforms with phase that lags by 90° with a high degree of precision. The CT6840 Series AC/DC Current Probes are ideal for measuring power waveforms with a digital oscilloscope and power meters. |
