In-Depth Performance Breakdown
Vicimeter VC1508PD Exclusive High-Voltage Capability
Equipped with full test voltage tiers including the industry-exclusive 2500V high-voltage gear, it serves as a mandatory tool for insulation testing on new energy vehicles, high-voltage power cables, large transformers, high-voltage motors and electrical assets rated above 2kV. Its maximum 50GΩ resistance range delivers superior sensitivity to capture subtle insulation anomalies during high-voltage diagnostics.
Vicimeter VC1508PC All-Round Low & Medium-Voltage Coverage
Supports 50V–1000V test voltages, fully covering regular insulation inspection for low/medium-voltage motors, power distribution cabinets, residential wiring and small-to-medium industrial machinery. The 20GΩ measurement limit fully satisfies most routine low-voltage maintenance tasks with outstanding versatility.
Fluke 1508 Low-Voltage Only Limitation
Its maximum test voltage caps at 1000V with a mere 10GΩ top resistance range, restricting it exclusively to medium/low-voltage assets. It cannot perform insulation diagnostics for any equipment rated 2kV and above, creating clear constraints for high-voltage operation sites.
Critical Timed Measurement Distinction
Both VC1508PD and VC1508PC integrate dedicated TIME timed testing for extended continuous insulation monitoring, ideal for voltage withstand testing and long-duration equipment condition tracking for refined diagnostics. The Fluke 1508 lacks timed measurement and only supports instantaneous spot checks, making it unsuitable for prolonged, precision monitoring workflows.
