Application Notes

Functions & Configuration

CTB series current probes are current probes capable of measuring both DC and AC current. They are openable/closable clamp-type current sensors for AC/DC current.

Features:

● High accuracy, typical value 0.3%

● Good frequency characteristics and temperature characteristics

● High bandwidth

This product needs to be used with the CTB104 (four-channel sensor unit), and is mainly used for high-precision current measurement. When used with a power analyzer, it enables power analysis.

1. Product electrical specifications

● f.s. maximum display value or scale length (indicates rated primary current range)

● rdg. reading (indicates the value currently being measured and the value currently indicated by the measuring instrument)

● Input positive弦Waveform, conductor center position, CTB104 combination, excluding various influences

● Measuring instruments with input resistance of 1MΩ or above

● Please demagnetize and zero correctly before measurement
