1. WIDE MEASURING RANGE. Designed for a low impedance and standard duty fence controllers. 8 Neon lights indicate voltage from 2kv to 12kv. Higher measuring range than normal item. Though not as bright as LED, do not need battery 2. WIDELY APPLICATION. Measuring voltage on any metal wire, poly wire, rope and poly tape. Test Fence line, Energizer, Ground System, Hook Up Wire and Fence Components. Used in Farm, Home Garden, Sheep, Pet, Horse and Livestock Fencing. 3. UPDATE. Black outer case does not emit excess light will not affect reading. Top Probe design has a better contacting with fence tap than curved hooks type. 4. EASY TO USE. Hold top probe to the fence.

Easy to carry. Operation 1. Make sure your fence is wired properly 2. Touch the short probe at the top of the meter to the charger post or wire to get a voltage reading 3. Visible Reading is not as bright as LED, Not waterproof Warning 1. The tester can only be used to test standard duty, low impedance electric fences. 2. People with pacemakers should not use the tester. 3. Keep the tester dry. Don't use the tester if the tester or your hand is wet. 4. Inspect the tester before use.
