Key features and benefits - Built-in probe storage slot: When the probe is not in use, it can be inserted into the slot for convenient, secure storage. - Flexible telescopic extension cable: Extends the working distance to reach targets in tight or hard-to-access environments, enabling more versatile measurements. - AA battery powered: Operates on a standard AA battery with straightforward, easy replacement in the field. - Two operation modes: The device offers two modes for the test instrument, selectable by rotating the mode wheel for quick adaptation to different tasks. Use scenarios - Industrial maintenance and equipment testing: Keep the probe safely stored in its slot when not measuring, extend reach to components located behind panels or inside machinery with the telescopic cable, and switch modes as needed for different measurement tasks. - Field inspections and surveys: The AA battery power provides true portability without reliance on mains electricity, while the extended reach and quick mode switching support efficient on-site assessments. - Lab or workshop testing: Use the two modes to handle varying measurement requirements, with secure storage for the probe when it is not in use and easy battery replacement to minimize downtime.
