M73  is designed to perform Global Earth Resistance measurements and trip out time test on AC RCD type according to VDE and IEC common standards on typical urban electrical installations.
 
M73 meter also include others features as phase sequence with 1 wire method, leakage current with optional transducer clamp and a powerful DMM function for TRMS measures of voltage and current ideal for troubleshooting operations both in civil and industrial environments.
 
Voltage and current peak measure on 1ms it’s also ok for inrush current evaluation of electrical motor devices. A large LCD display for easy readings, a modern and ergonomic external case, a innovative electronic function selector for easy to use and a protection rubber holder to prevent accidental damaged.
