- Page 2 Thank you for choosing an Astro-Med data acquisition recorder. This Quick Start Guide was prepared to help you become acquainted with your recorder as quickly as possible. We even include sample exercises so you can become familiar with the basic operation.
- Page 3 & & Dash “HF” screen highlighting the Menu Bar and Control Panel MENU BAR The menu bar is a group of drop-down menus located across the top of the display. All Dash “HF” modes and features can be accessed from this menu. Options available from the menu bar will vary based on the mode of operation (Scope, Realtime or Review) used.
- Page 4 “ ” “ ” The Dash “HF” has three modes of operation, Scope, Realtime, and Review modes. Scope Mode: Scope mode acts like a digital storage oscilloscope, providing high time-base resolution for viewing high frequency signals and provides waveform scrolling, monitoring, and data capture capabilities. Scope mode is the default mode of the Dash “HF”.
- Page 5 Scope mode acts like a digital storage oscilloscope, providing high time-base resolution for viewing high frequency signals and provides waveform scrolling, monitoring, and data capture capabilities. In the following hands-on exercise, you will set up a channel to monitor a 10 kHz sine wave in Scope mode. Next, a Scope screen capture and data capture will be set up to record when the signal changes voltage amplitude.
- Page 6 Select the Continuous icon in the Scope Capture Type section of the Scope Settings Select Scope Capture window. The Continuous icon will have a check mark in it when selected. Press the OK Type icon located in the lower right hand corner of the Scope Settings window. Dash “HF”...

- Page 9 You should now see a strait line frequency measurement. Choose Measurement Type >> Measure Signal Average on the Channel Information window. The frequency measurement is displayed in Frequency the Channel Information window. Dash “HF” Frequency Counter Measurement Choose Setup >> Amplifier Channel Settings (Analog Channel Setup) from the menu bar, press the Advanced Setup (graduation hat) icon located in the first row of icons on the bottom left hand corner of the Amplifier Channel Settings (Analog Channel Setup) Turn off the Frequency...
- Page 10 Choose Analysis >> Filters from the menu bar. Highlight Waveform 1 on the Filter Turn off the Filter window. On the Filter settings Select Filter >> Off. Press OK on the Filter window. The 10 kHz sine wave will now be on the Dash “HF” screen. Close Channel Close the Channel Information window by pressing the X in the top right hand corner of the Channel Information window.
- Page 11 Scope Mode Capture: Capture a 10 kHz 5V pk-pk sine wave to the Scope Screen Scope Mode Capture: Capture a 10 kHz 5V pk-pk sine wave to the Scope Screen We will now set a trigger so that when the 10 kHz 5V pk-pk signal is applied. The unit will trigger and capture the event to the scope screen.
- Page 12 Press Trigger OR to highlight in yellow. Since we reset the system defaults at the beginning of this exercise, the Manual Trigger input and Set Software Trigger Trigger output will be highlighted. Press the Trigger Level icon (1 icon in the row of icons at the bottom) to open the Waveform Trigger settings Trigger Level menu.
- Page 13 To save the Scope data, select File >> Archive as Data Capture Record >> Entire File on the pull down menu. The Save Scope Capture File screen will appear. Touch the blank Save Scope Screen Data space above Filename on the Save Scope Capture File screen. A keypad will appear. to Disk Enter the filename Scope1.
- Page 14 III. Scope Mode Data Capture: Capture a 10 kHz 5V pk-pk sine wave to the Data Capture Drive III. Scope Mode Data Capture: Capture a 10 kHz 5V pk-pk sine wave to the Data Capture Drive Using the trigger settings from the previous section, we will now set a trigger so that when the 10 kHz 5V pk-pk signal is applied the unit will trigger and capture the signal to the data capture drive.
- Page 15 Set capture for one In the Automation Box, be sure that both the Auto Re-Arm & Auto Archive icons are not record checked. At this point, your Capture Setup Window should look like the image below. Capture Setup Window Save and exit data Press OK.
- Page 16 In the following hands-on exercise, you will set up a channel to monitor a 9 Volt battery in Real-time. Next, a data capture will be set up to record when the battery voltage is applied. Finally, the captured data will be reviewed. The ACTION on the left-hand side describes what is to be done.
- Page 17 Choose Setup >> Amplifier Channel Settings (Analog Channel Setup) from the menu bar. Highlight Waveform 1. Span and Center adjustment keypads Press the Span column. The Span Adjustment box will appear. Set Channel Span Press the digit “1” and “0” to select 10. Press OK on the Span Adjustment box.
- Page 18 Set up a single data capture on Channel 1 only for 10 seconds. Of the total capture time, two seconds of the capture should show what the signal looked like before the battery voltage was applied. The sample rate will be 1,000 samples per second.
- Page 19 Below the waveform selection window, in yellow text, the Record Duration should be 10 Verify time of capture seconds, the Pre-Trigger Duration should be 2 seconds. Set capture name Press the Base Filename box, erase the name DCR and type 9V Battery Test In the Automation Box, be sure that both the Auto Re-Arm &...

- Page 23 There are two hard drives in the Dash “HF”. The first is the Windows (System) drive and the second is the data capture drive. During data capture, the data is streamed to the data capture drive. Once the data capture is complete, the file can be reviewed on the Dash “HF”.
- Page 24 Browse for Folder window Note: If you are using the standard Dash “HF”, the DVD+RW is assigned drive letter D. USB storage devices are drive letters E and F. If you are using the high security version, which does not have a DVD+RW drive, USB storage devices are drive letters D and E.
- Page 25 Engineering units provide the capability to display user-selected units instead of voltage. All signal information enters the Dash “HF” as voltage. However, converting the voltage unit to an alternative unit of measure may be desirable in applications that measure current, pressure, strain, or any non-voltage unit. This allows the Dash “HF”...
- Page 26 Under the Engineering Units box on the User Unit Setup – Waveform 1 window there is a section named Scale. Now that you have entered AMPS, you can now enter either AMPS/Volts or Volts/AMPS. Since our probe has a 10mV/A output, we will enter 0.01 into the Enter Scale Volts / AMPS box.
