    PULSAR MEASUREMENT 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 36: Test Mode

    FLOWCERT LITE (UL) INSTRUCTION MANUAL 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.

  • Page 37: Using The Serial Interface

    PULSAR MEASUREMENT Using the Serial Interface The RS232 serial interface is used to communicate between the FlowCERT Lite and a PC using the optional Ultra PC and other associated Pulsar software packages, to obtain information such as data logging and view echo traces upload, download and save parameter files.
