The Model R1L-BR1 bond meter from TEGAM Inc., Geneva, OH, is a purpose-built, rechargeable, battery-powered portable instrument for ground bond measurements. The device has five ranges with F.S. values from 2 milliohms to 20 ohms with resolution on the lowest range of 1 microohm and its accuracy is 0.25% of reading ±1 count. Selected for deployment in support of the Kiowa Warrior armed reconnaissance helicopter, the device can be used to make fixed and rotary wing aircraft bond measurements in manufacturing and flight-line maintenance, verify electromagnetic shield integrity between connector back shells, measure static discharge wicks for electrical continuity, and inspect conductive coatings for coverage and thickness.
