Kyoritsu Electric Meter (KYORITSU) 5720 Telescopic High and Low Voltage Detector (AC 80V ~ 7,000V)

This product uses sound and light to indicate whether low-voltage or high-voltage AC power lines and electrical equipment are charged. It detects "low voltage" when the telescopic pipe is retracted and "high voltage" when extended. The telescopic insulated pipe makes it convenient to carry. The detector is splash-proof and allows for checking the built-in battery and internal circuitry before use. Specifications: [Operating Voltage Range] AC 80V - 7,000V [Operating Frequency] 50/60Hz [Start Voltage] "Low Voltage" (retracted state) bare wire 80V, "High Voltage" (extended state) bare wire 400V (*Insulated wire 3,300V). The voltage value indicates the voltage to ground, and indicates that the detectable voltage is above this value. * indicates the value when detecting voltage through the insulation of outdoor cross-linked polyethylene electric wire (core diameter 5mm). The start voltage decreases as the core diameter (cross-sectional area) increases. (Detection sensitivity increases.) [Operation Indicator] Sound: 50 dB or more at a distance of 1 m. Light: Visible at a distance of 1 m in 8000 lx brightness. [Insulation Resistance] 200 MΩ or more (between the sensor and grip) at 1,000 V with a 1000 V megger (when extended). [Dielectric Strength] 20 kV AC for 1 minute (between the sensor and grip) (when extended). [Leakage Current] 100 μA or less during dielectric strength test. [Batteries] Two AAA R03 (1.5 V) batteries. [Operating Temperature and Humidity Range] -10°C to +50°C, 85% or less. [Weight] Approximately 230 g (including batteries). Country of Manufacture: Japan
