Testo 770-1 TRMS Hook Clamp Meter

Description

The Testo 770-1 (0590 7701) is a True RMS hook-style clamp meter, primarily used for non-contact measurement of AC/DC current, particularly on tightly packed power cables. Its unique fully retractable pincer arm makes it easier to work in confined spaces like crowded switching cabinets.

Key Features

• True RMS: The Testo 770-1 provides accurate True RMS measurements, which are critical for measuring non-linear electrical loads.
• Retractable pincer arm: The innovative design includes a fully retractable pincer arm that can hook onto individual cables in tight spaces, improving safety and ease of use.
• Automatic detection: The meter automatically detects and selects the measurement mode for AC/DC current and voltage. It also auto-detects other parameters like resistance, continuity, diode, and capacitance.
• Auto AC/DC: The automatic selection between AC and DC modes for voltage and current simplifies operation and reduces the risk of incorrect readings.
• Measurement of electrical parameters: Besides current and voltage, the meter can measure resistance, capacitance, and frequency.
• Inrush current measurement: This feature allows the meter to measure the initial surge of current when equipment is first switched on, which is useful for electric motor diagnostics.
• Data functions: Includes Min/Max and Hold functions to capture and store measurement readings.
• Large two-line display: The display shows readings clearly and distinctly, according to testo.com.
• Safety rating: It has an overvoltage category of CAT IV 600V and CAT III 1000V, providing a high level of safety.
• Accessories: The standard delivery scope includes batteries and one set of test leads.
