Compact current clamp with multimeter measurement functions for safe AC measurement up to 400 A. The ergonomic housing allows for one-handed operation and is very robust due to the molded soft rubber protection. The clamp multimeter combines standard multimeter functions with the convenient advantage of non-contact AC measurement. With the clamp multimeter, there is no need to interrupt the circuit for current measurement. Reliable measurement results with ISO calibration. ISO calibration is required when the measuring device is used for measurement tasks in an ISO9001 certified environment. An ISO certification is also helpful and often a prerequisite for experts, acceptance bodies, or testing laboratories.
