DISCUSSION

ACTION

Default the Dash 16u

Select Chart 1 (16 individual channels) [MODE] [RUN CHART 1]

Set speed to 5 mm/sec

Stop the chart paper

Set Channel #1 to be 0 - 11 Volts FS

Input battery voltage into Channel #1

Run the chart

Stop the chart paper

Measure the battery voltage

using the color display

Remove battery voltage

9. SAMPLE EXERCISES

Exercise #1: 9 Volt Battery Test

Items needed: 9 Volt battery. Signal input leads.

Monitor the voltage of a 9 Volt battery input into Channel #1 (Keep in mind

that a new 9 Volt battery can have a voltage higher than 9.5 Volts). Use a

sixteen grid chart. Set up the channel so that when there is no signal, the

waveform trace will be at the bottom and when the 9 Volt signal is applied, the

waveform trace will be near the top of the channel. The signal will be seen on

the color display as well as on the chart paper.

Next, a data capture will be set up to collect data when the battery voltage is

applied.

HOW TO

[SYS] [SYSTEM SETUP] [SYSTEM DEFAULT] [YES]

[5] [SEC] Common speeds have dedicated keys on front panel of Dash 16u.

[RUN / HALT]

[AMP 1] One key for each of two amplifiers.

[ADVANCED]

[CHANGE AMP TYPE ...] The Dash 16u has four amplifier types.

[SET TO SINGLE-ENDED] Select the single-ended amplifier type.

[EXIT] [SET TO 40 V] Set the attenuator range to 40 Volts.

[EXIT] [SET RANGE] Turn encoder wheel until range is set to 11 Volts.

[SET OFFSET] Turn encoder wheel until offset is set to +5.5 Volts.

[EXIT]

Use the banana jack input connection located on the side of the Dash 16u.

[RUN / HALT] The signal for Channel #1 is now be close to the top.

[RUN / HALT]

[FREEZE DISPLAY] Toggle the time cursor button until it reads

[TIME CURSOR A]. Turn the encoder wheel to move Cursor A. Observe the

voltage readings shown at the bottom of the display. Experiment with Cursor B

and then Cursors A+B. Amplitude and time measurements between the cursors

are given on the bottom of the display.

When finished, run the display [RUN DISPLAY]
