產(chǎn)品詳情

The model 309 Digital Earth Resistance Meter （Earth Ground Meter） is a small, compact, battery powered, professional meter. This easy-to-use meter is invaluable to electricians and contractors who need to ensure the "ground" quality and effectiveness of buildings, structures, equipment or electrical systems. A good earth ground is required for new buildings or structures needing to pass required electrical codes. Older buildings can lose a good, effective earth ground connection over time. This can happen after a building or structure has been struck by lightning

技術(shù)參數(shù)：

-Measure Earth Resistance （20/200/2000 ohm ranges）
-Measures Earth AC Voltage to 200VAC （40 to 500Hz）
-Timed function test turns output off after a 3 to 5 min continuous test
-2mA Measuring current measures resistance without tripping circuit breakers
-Data Hold
-Small Light Weight
-Auto Power Off
-IEC 1010 CAT III 200V / CE
-Included: Test Leads, Auxiliary Earth Spikes, Carrying Case and Batteries
