The Kyoritsu 1011 digital multimeter is a versatile electrical measuring instrument for professional and technical applications. It offers comprehensive functionality with AC and DC voltage measurement up to 600 V, AC and DC current measurement up to 10 A, resistance measurement up to 40 MΩ, continuity testing, diode testing, capacitance measurement up to 100 µF, frequency measurement up to 10 MHz, and duty cycle measurement. Additional features include temperature measurement, a data hold function, and a relative measurement mode for comparative readings. The device operates with automatic and manual range selection for various measurement scenarios. Safety is prioritized with CAT III 300 V certification to ensure protection against transient voltage spikes in industrial environments. The multimeter includes a robust rubber protective cover for shock resistance and durability in field use. Energy management features include automatic shutdown after 30 minutes of inactivity to conserve battery life. The display offers 4000 counts resolution for precise measurements across all functions. The product comes with test leads (model 7066A), a temperature probe (model 8216), and built-in ceramic fuses rated at 0.8 A/600 V (model 8918) and 10 A/600 V (model 8919) for circuit protection. It is powered by two standard AA batteries (type R6). The multimeter housing is made from durable plastic materials with green accents for professional identification. This instrument represents a successor model in Kyoritsu's measuring tool range and upholds the brand's reputation for reliable electrical testing equipment, suitable for maintenance technicians, electricians, and engineers who require accurate electrical parameter measurement capabilities.
