T477W Bonding Meter Ideal for aircraft system bonding testing. The unit is contained in a protective carrying case complete with the C22161 pistol grip probe set, battery charger, and operator’s manual. Power is obtained from a rechargeable battery pack. Battery capacity is adequate for eight (8) hours of continuous operation. Power is conserved by a 52 second timer which automatically powers down the display. Operation and display are initiated by depressing the TEST button. Built-in display illumination provides for use at nighttime or with inadequate ambient light. These features allow high accuracy and simplified set-up. www.avtronaero.com The low voltage and current output will not cause ignition of flammable gas, as certified by Underwriters Laboratories per UL 913, standard entitled “Intrinsically Safe Apparatus and Associated Apparatus, for use in Class I, II, and III, Division I Hazardous Installation.” The meter is approved for use in Class I, Groups A, B, C, or D, which includes hydrogen and gasoline flammable vapors. The Model T477W Bonding Meter is designed to accurately measure resistance, less than 2.0 ohms, as required by electrical bonds.
