II. Data Capture

DISCUSSION

ACTION

Enter data capture setup

Format memory

Select capture of all channels

Set sample rate to 1 kHz

Set record size to 64 Ks

Set trigger window to 10%

Set capture for one record

Be sure auto-triggering is OFF

Enter trigger setup

Enable waveform triggering

Set up the logic for triggering

Pick waveform(s) for triggering

Set up the level for triggering

Run the chart

Arm for capture

Set up one data capture for 7.28 seconds. The capture should be triggered when

the battery voltage is applied. The data capture should be a total of 7.28 seconds.

Of the total capture time, 0.728 seconds of the capture should show what the

signal looked like before the battery voltage was applied.

HOW TO

[SYS] [SETUP DATA CAPTURE]

[ADVANCED] [FORMAT CAPTURE MEMORY] Use encoder wheel to

select 16 records x 256 Ks maximum. [BEGIN] [BEGIN] [EXIT] [EXIT]

[SET CHANNELS TO STORE] [DEFAULT]

[EVENT CHANNELS] Toggle to SAVED to include event markers with the

capture. [EXIT]

[SET SAMPLE RATE] The number of samples per second. In general, select

at least ten times the frequency of your signal or the frequency of any changes in

signal. Turn encoder wheel until sample rate is 1 kHz.

[SET RECORD SIZE] The Dash 16u will give you the amount of time that data

will be captured based on the record size and the sample rate. This is shown

under the duration field. Turn encoder wheel until record size is 64 Ks.

[SET TRIGGER WINDOW] Placing the trigger at any point other than the

start of the capture window will allow for pre-trigger data to be captured. Turn

encoder wheel until trigger window is 10%.

[SET OPERATION] You can capture one record or re-arm for more captures.

Turn encoder wheel for single capture.

[ADVANCED] [AUTO TRIGGER] If auto-triggering is ON, toggle to OFF.

[SYS] [SETUP TRIGGER]

[WAVEFORM] Waveform should be toggled to ON position.

[TOGGLE LOGIC] Insure that OR logic is chosen.

Turn encoder wheel so that only Channel #1 is selected.

[SETUP WAVEFORM] [SET CHANNEL] Turn encoder wheel to select

Channel #1. [SET TYPE / CLASS] Use wheel to select level - above for type of

trigger. [<<FIELD>>] Turn encoder wheel to 80% (8.8 volts).

[RUN / HALT]

[ARM] This key is located near the encoder wheel. The Dash 16u is now

recording pre-trigger data, waiting for the trigger.
