Collect DC Volts data


DC Volts mode lets you collect data on one, two, three, or four channels over time to produce a strip plot. The analyzer can connect to a specific number of points or it can continuously collect data until you stop the measurement.

Note: When you measure DC Volts, Emerson recommends setting the sensor type as non-standard, a sensitivity of 1.0, Power = OFF, and the coupling mode to DC Coupled.


  1. Create a job or open Analyze from a route measurement point.
  2. From the Analyze main menu, press F1 Manual Analyze > F1 Set Analyze Mode.
  3. Use the up and down arrow keys to select DC Volts.
  4. Press Enter.
    The Analyze Setup screen appears.
  5. Set the following options as necessary.
    Option Description
    F4 Set Number Points For Non-Continuous mode, enter a value between 2 and 6,400 to set the number of measurement samples to collect. For Continuous mode, the analyzer overwrites the oldest data. See F8 Set Collection Mode. The default is 2,000.
    F5 Set Time Inc Enter a value between 0 and 60 to set the seconds between each measurement. The default is 1.
    F7 Tach Setup Set up the tachometer parameters. See Set up a tachometer in Analyze.
    F8 Set Collection Mode Select Continuous or Non-Continuous. Continuous collects the required number of points and continues collecting data while replacing the oldest data with the newest data. Non-Continuous collects the required number of points and stops. The default is Continuous.
    F9 Set Alarm Level Enter a value between 0 and 25,400 to set an alarm level for the measurement. If the measurement exceeds the level, the analyzer beeps until the acquisition stops or the signal drops back below the alarm level. Enter 0 to disable the alarm. The default is 0.
    F11 Set Time Span Enter a value between 10 and 9,999 to set the time span of the trend plot. The default is 10.
    F12 Input Setup Set up the number of inputs, a non standard type sensor, and the data units.
  6. Press Enter to collect the data.
    One or more plots display the data.
  7. Press F9 Store Data to save the data to a route or a job, or press F8 Start to redo the measurement.
