Clear- Alternating Current (AC): Ability to measure alternating current (AC), such as the current in household and professional electrical installations. Used for testing panels, wiring, and AC electrical devices.
- Direct Current (DC): Ability to measure direct current (DC), which is found in batteries, photovoltaics, cars, and electronic circuits. It is useful for maintenance and diagnostics in DC systems.
- Non-Contact Voltage Detection (NCV): The NCV (Non-Contact Voltage) function allows voltage detection without direct contact with bare wires or terminals.
- Temperature Measurement: They allow temperature monitoring of pipes, refrigerants, and HVAC components. Essential for cooling, heating, and burner maintenance work.
- Capacitor Capacitance Measurement: Ideal for industrial electricians and HVAC technicians. They allow the immediate diagnosis of worn start capacitors in motors, pumps, and compressors.
- True RMS: The True-RMS method will provide the correct value of the alternating quantity regardless of its waveform.
- with Wires: It has measurement terminals that have a red wire for positive and a black wire for negative.
- Inrush Current: Suitable for maintenance of motors, pumps, and air conditioners (HVAC), where capturing the initial starting current is required.
- VFD Mode / LPF : Suitable for maintenance of modern motors with variable frequency drives (Inverters/VFD), HVAC systems, and industrial automation.
- CAT II: Suitable for measurements on household appliances, sockets, and portable electric tools that are connected directly to the power network. Provides protection against surges that occur in typical low-intensity electrical installations.
- CAT III: Designed for measurements in fixed electrical installations, such as electrical panels, three-phase circuits, motors, and building wiring. Provides increased protection against higher voltage surges and energy spikes.
- CAT IV: It is suitable for measurements at the source of the electrical installation, such as power meters, main power supplies, and external supply lines. It offers maximum protection against strong voltage surges.
- Slim / Narrow Panels (< 25mm): Narrow spaces, automation panels, electronics, and thin wiring.
- Standard - Domestic / Commercial (25-35mm): Covers standard residential/commercial installations (cables up to ~250 mm²).
- Heavy Duty - Industrial (36-75mm): Thick industrial cables, main power supplies, and dual conductors.
- Flexible Conductor / Flex (> 100mm): Cable bundles, busbars, and places where the rigid clamp cannot physically fit through.
