Data Sheet

Model 309

Digital Earth Resistance Meter

Model 309

The model 309 Digital Earth Resistance 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 sys-

tems. 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.

Features

■ Measure Earth Resistance (20/200/2000Ω ranges)

■ Measures Earth AC Voltage to 200VAC (40 to 500Hz)

■ Timed function test turns output off after a 3 to 5

minutes 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
