Description
Testo 755-2 Current/Voltage Tester – Overview and Capabilities
Testo 755-2 is a universal voltage/current tester, fully ready for the most important tasks. It is designed to determine the presence/absence of voltage, measure voltage, check circuit continuity, and measure current and current consumption.
Automatic parameter detection and a built-in flashlight make working with the instrument easy and reliable.
Key Advantages and Differences from testo 755-1
- Extended Voltage Range: The voltage measuring range is increased up to 1000 V.
- Phase Detection: Ability to perform single-pole phase testing to quickly identify live conductors.
- Field Detection: Can display the direction of the rotating magnetic field.
- Convenience: Replaceable measuring leads, eliminating the need to purchase a new instrument if the leads are damaged.
- Additional Function: Built-in flashlight for illuminating the measurement area.
Application Areas Overview
- Checking for the presence or absence of voltage in electrical circuits or systems (according to standard DIN EN 61243-3:2010).
- Measurement of current consumption.
- Determining the direction of the rotating magnetic field.
- Checking Residual Current Devices (RCDs).
