The portable, pocket-sized, battery-powered voltage source is unique because it sources stable AC/DC voltages for both LoZ and HiZ instruments. Works with multimeters, clamp meters, voltage testers, and two pole testers.
Reduces the risk of shock and arc flash by removing unnecessary exposure to a potentially hazardous electrical environment while verifying the functionality of test tools before and after absence or presence of voltage is checked.
Test Before Touch
Provides a safe method to verify that your electrical test tool is operating properly before you conduct further tests. The concept of "Test Before Touch" (TBT) or three point test method involves testing your meter against a known live source before and after the actual measurement. This sequence verifies that your test tool is operating properly during the actual measurement.
Designed for safety and compliance
Safe and easy method for verifying proper operation of your test tool before attempting to test for either an energized source or a de-energized source without the need for cumbersome PPE, or in cases where no known voltage source is available. Your environment may still require minimal PPE such as hard, safety glasses or earplugs when using a proving unit.
