Once you have set up the analog, data capture and trigger parameters, you can press the [ARM] button (near the encoder

wheel) to start a data capture record. The Dash 16u will be ready for the trigger to complete the record.

Once a data capture record is complete, several things can be done with the data. It can be reviewed on the color display,

played back to the chart paper, copied to the Zip disk or sent to a computer by ethernet.

Throughout the setup of the Dash 16u, you can use the Help sheets to guide you. The System Report and Chart Report

provide much useful information. The manual gives details on the keystrokes to achieve what you want to do with the

Dash 16u. The above lists the basics of the Dash 16u. Under many of the menus are additional choices for more

advanced capabilities of the Dash 16u.

Should you require additional assistance, you can contact our Technical Support Department toll-free at 800-343-4039 or

For window, level and slope triggering, percentage values are listed. This

percent value is with respect to the edge-to-edge location on the chart where 0%

is the bottom of the chart, 50% is the middle of the chart and 100% is the top of

the chart. Knowing the signal placement on the chart from analog setup, you can

pick the appropriate percentage level. See exercises in Section 9 for use of

waveform triggering.

Allows TTL or switch closure to ground trigger (see utility port pin-out).

Produces a trigger at pre-defined periods. For example, if it is set to one hour,

then every hour there will be a trigger. Also, you can set a one-time trigger at a

pre-defined date and time.

8. DATA REVIEW

[MODE] [DATA RECORD REVIEW] [SCREEN PREVIEW]

Part or all of the data can be acted upon. To help decide what part of the data is

of interest, the color display allows preview of the data record.

In the screen preview, there are two cursors (A, B) for selecting data. You can

page forward and backward through the data as well as expand or compress the

time base. The lower part of the display shows the time and amplitude

measurements.

Once you have selected data of interest, you can print the screen to chart paper,

create a .BMP file on Zip disk, or play out the data to the chart paper.

[MODE] [DATA RECORD REVIEW] [SETUP PLAYBACK]

For playing the data to the chart paper, there is a dedicated set up menu.

Here is where the format for playback is selected (one of the four charts,

numeric, X-Y plot). Also, you can select how much of the data to play back and

whether to compress or expand the timebase.
