HT Instruments HT77C Clamp meter

The innovative HT77C residual current ammeter is particularly suitable for accurate measurements of the smallest currents in the µA and mA range. This current clamp is mainly used for preventive maintenance and fault location in which the RCD (FI) repeatedly triggers unintentionally. (E.g. due to an insulation fault or a vagabounding fault current). The HT77C is also suitable for measuring protective conductor & differential currents on electrical devices (DGUV regulation 3). The HT77C also has a switchable low-pass filter to eliminate the harmonics during measurements and allows the user a wide range of applications. The jaws are fully shielded to minimize external electromagnetic interference and to obtain accurate results in the µA range. Functions: · AC TRMS current (TRM from 0.001mA to 60A) · DATA HOLD, max and min function · Low pass filter for detecting harmonics · Measuring point lighting with white LED · Display with background lighting. · Data logger function in conjunction with THE app HTLeakage...
