Avtron T477W Features and Specifications *

The Avtron Model T477W Bonding Meter is a self-contained AC resistance meter designed to test very low resistance electrical bonds and is Ideal for aircraft system bonding testing. 


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.

 

The Model T477W Bonding Meter is designed to accurately measure resistance, less than 2.0 ohms, as required by electrical bonds. The unit is approved for use in hazardous environments such as around aircraft, fuel installations, fuel cells, and gas systems.

 

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.

 

Four resistance ranges are provided for measurement sensitivity. These are 2, 20, 200 and 2000 milliohms full scale. Operation of the TEST button automatically changes the range to the next highest range each time it is depressed. Continued operations of the TEST button re-cycle the range changes.

 

Resistance measurements are made using a pistol grip probe connection. The pistol grip probe set (P/N C22161) is easy to use with convenient pistol grips for firm control and needle points for sure penetration of surface coatings. This probe set is also easy to use in tight areas such as around wing tanks.

 

  • Intrinsically Safe
  • UL Approved. Std. 913, Cl. 1, Groups A, B, C, or D
