•

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 4u 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.

4. REAL-TIME RECORDING FUNCTIONS

5. SETTING UP CHARTS AND GRIDS

The Dash 4u has four programmable charts. They are defaulted at the factory

prior to shipping. The defaulted charts are four grids, six grids, one grid, and

four grids with eight event markers. 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.
