•

Four available chart formats: Design grid for number of channels. Pick to overlap some, all or none of the channels.

•

Data logger (numeric output): Select rate at which to print values.

•

Timed recording: Pick one of four charts. Select the start and end times for recording.

•

Dual Speed Recording: Select two chart speeds at which to run the paper and select either the trigger or time duration

to switch between the speeds. The most common use is recording at the first selected chart speed, utilizing waveform

triggering to change to the second chart speed for a predetermined amount of time. At that point, the recorder will

automatically switch back to the first selected chart speed, awaiting another trigger.

During real-time recording, the display will show your signals. At the same time, you can print to paper using the

[RUN / HALT] key.

The Dash 16u gives you total control over chart layout. You can set individual channel widths, channel location, grids

ON/OFF and major/minor division sizing. You are also able to suppress or enable waveform printing as well as vary the

waveform trace thickness. Further, you can overlap some or all of the channels.

CUSTOMIZING A CHART

[SYS]

System key used for setting up various parameters for the Dash 16u.

Design or modify an existing chart. Edit text labels. Set up data

capture and triggering. Save or recall a system set up (Zip disk).

Other system functions such as real-time clock, display colors,

defaulting settings and software upgrade.

[MODE]

Select and run any of the four available charts. Select data logger

(numeric), timed recording or dual speed mode. Select captured data

to review as well as importing and exporting data to Zip disk.

5. SETTING UP CHARTS AND GRIDS

The Dash 16u has four programmable charts. They are defaulted at the factory

prior to shipping. The defaulted charts are sixteen grids, eight grids, four grids

and one grid. You may find this a convenient place to start.

At any time, you can default the charts as follows:

[SYS] [CUSTOMIZE CHART] [DEFAULT ALL CHARTS]

[MODE] [RUN CHART X] where X = 1 or 2 or 3 or 4.

Immediately, you will see the waveforms scrolling across the color display as

well as the chart paper begins to run. Use the [RUN / HALT] key to stop the

paper.

If you don't find a chart you like from one of the four charts programmed in your

Dash 16u, you can change the chart in two different ways.

•

The first is Auto-Chart: [SYS] [AUTO-CHART SETUP]

Here the Dash 16u walks you through selecting how many channels you

want and whether to overlap them or display them individually. You are

prompted to save this chart to one of the four available charts.

•

The second method is to set up each channel's grid parameters manually:

[SYS] [CUSTOMIZE CHART]... Note that the changes made will affect

the current chart that you are working with (Chart 1-4).

There are three parameters involved with displaying a channel:

Grid, waveform trace and text buffer.
