HT Instruments M75 Multifunction Tester

Description

The HT Instruments M75 is a multifunction safety tester and True RMS (TRMS) digital multimeter for testing electrical installations and mapping LAN network cables. It is a versatile, professional-grade device known for its compact size and user-friendly features, including an "AUTO" function that performs a sequence of safety tests with one button.

Key Features

• Multimeter capabilities: The M75 includes a True RMS digital multimeter for measuring AC/DC voltage and resistance. When used with an optional external clamp, it can also measure AC/DC current and AC leakage current.
• Continuity of protective conductors with 200mA
• Insulation resistance measurement with a 500V DC test voltage
• RCD (Residual Current Device) trip-out time tests for Type A and AC RCDs
• Global earth resistance without tripping the RCDs
• Phase sequence indication using a patented single-pole method
• LAN cable mapping: The instrument includes an RJ45 connector and remote units to test the wire mapping of LAN cables. This function helps identify common issues like short circuits, broken wires, and split pairs.
