High-precision, intelligent burn-proof universal electrical testing instrument designed for on-site measurement of voltage, current, and phase relationships.
Product Overview
This high-precision, handheld dual-channel input measuring device is specifically designed for field measurement applications. It conveniently measures phase angles between U-U, I-I, and U-I, identifies inductive and capacitive circuits, determines three-phase voltage sequence, verifies transformer connection groups, and tests secondary circuits and bus differential protection systems.
Current input via clamp-on transformers eliminates the need to disconnect circuits under test. When measuring phase angles between U1 and U2, the two input circuits are completely isolated, preventing potential short circuits and instrument damage. The high-contrast LCD screen features 25mm-tall characters with approximately 70° adjustable viewing angle for optimal visibility. The engineering insulating material housing with rubber anti-vibration protective cover ensures safety and reliability.
External reference frequency electromagnetic field interference: should be avoided
