The EA7n is an analysis tool designed to meet the needs of elevator consultants and inspectors. Low-cost and easy to use, the EA7n plugs into a Windows laptop or tablet for virtually unlimited data recording.

The EA7n is portable and easy to install

EA7n on door
  • Attach the EA7n to the door frame with removable 3M Command Strips, or set it on the floor.
  • Place a colored 3M Post-It on the door to mark the closed position.
  • Plug the EA7n into a USB port on your Windows laptop.
  • Start the EA7n program on your laptop.
  • Run the elevator through its tests.
  • When done, remove the Post-It and Command Strips.
  • Use the data analysis program to review the data and generate reports.

The EA7n records:

  • Date, time, and duration of trip
  • Acceleration / deceleration
  • Door opening, closing, and dwell times
  • Limits exceeded
  • Speed
  • Jerk and Vibration
  • Landing number
  • Car distance traveled

The EA7n graphical tools let you view and analyze the data over any time period. For example, you can graph the landings visited and car distance traveled.


The EA7n generates reports over any time period, containing:

  • Number of trips
  • Number of door cycles, re-opens, and re-closes
  • Time of use by day and hour
  • Limits exceeded
  • Statistics for door times (open, close, dwell, pre-open, start delay)
  • Statistics for acceleration magnitude
  • Statistics for car speed
  • Vibration and ride quality
  • Total run time
  • Duty cycle
  • Graph of trips by hour of day
  • Graph of trip duration
  • Graph of acceleration duration
  • Graph of car speed
  • Graph of landings visited
