  • Page 10: About The Zenith 140

    The Zenith 140 operates on the principle of timing the echo received from a measured pulse of sound transmitted in air and utilises the unique DATEM software (Digital Adaptive Tracking of Echo Movement). This is an entirely new digital mapping technique developed especially for the Pulsar Ultra range.

  • Page 31: Using The Menu System

    PULSAR MEASUREMENT There are two means of editing parameters, directly or using the menu system. Each is now described. Using the Menu System The menu system has been designed to make the changing of parameters very simple. There are two levels of menu: Main Menu and Sub Menu.

  • Page 32: Directly Editing Parameters

    ZENITH 140 INSTRUCTION MANUAL Important Information You can tell which part of the menu system you are in, as the up/down level indicators, (arrows) next to the bar graph will indicate as follows: • Top level menu: Down arrow on, to indicate you can move down.

  • Page 33: Test Mode

    PULSAR MEASUREMENT Test Mode Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard simulation) or not (soft simulation), but the LED’s will always change colour as programmed, and the mA output will change in accordance to the chosen mode of operation.
