Digital Insulation multimeter YH 511 Specifications General Specifications Complies with IEC/EN 61010-1 1000V CAT III ，600 V CAT IV. 1000V DC Voltage，750V AC Voltage（TRMS）. 6600 Count（except for capacitance，temperature，insulation）. When the input terminals is V and COM, The overload protective voltage is up to AC 250 V (TRMS) ;When the input terminals is mA and COM, protective Current is 0.4A; when the input terminals is Hi and Lo , The overload protective voltage is 600V. Batteries：Four AA batteries (NEDA 15A or IEC LR6)Meter use 1000 hours; Insulation test use: Meter can perform at least 1000 insulation tests with fresh alkaline batteries at room temperature. These are standard tests of 1000 V into 1 MΩwith a duty cycle of 5 seconds on and 25 seconds off.
