  • AC (transducer driven ±1% of full scale)
  • Tracking: ± 1 1/2% DC; ± 2% AC ; vertical mounting
  • Repeatability: ± 0.5% DC and rectifier type
  • Shock resistant Pivot and jewel movement
  • In Accordance to ANSI C39.1


  • Military, Marine, Railroad and off road applications
  • Ideal for adverse (dusty) environments or severe applications, meets UL-1437 or IEC 144 or IP54
  • Rugged, High Shock Movement ideal for rough environments


The 101 series (AB17 and DB17) are internally illuminated meters used primarily in high vibration applications such as railway locomotives and off-road applications. Ideal for load and speed indication, etc. They are suited for applications where scale lighting and high accuracy is required. The wide radius pivot and jewel movement ensure accuracy and stability in the toughest environments.
