IV. Compatibility Instructions
This current clamp is a dedicated sensor for the MQ31 power quality analyzer, used for precise measurement of small currents, with a range covering 10mA~10A. It can complement TRC and NRC series Rogowski coils to achieve full-range current monitoring from 0.5A to 7200A.
Rogowski Coil: Responsible for high-current (600A~7200A) measurement
ST08 Current Clamp: Responsible for high-precision measurement of small currents (10mA~10A)
