7. SAMPLE EXERCISE (
9 Volt Battery Test )
Items needed: 9 Volt battery. Signal input leads.
I. Real-time Monitoring
Monitor the voltage of a 9 Volt battery.
Set up the channel so that when there is no signal, the waveform trace will be at the
bottom of the channel and when the 9 Volt signal is applied, the waveform trace will be
near the top of the channel.
ACTION
This column lists the sequence of steps to set
up a channel to record the 9 Volt battery,
set up a data capture, trigger the capture,
and playback the captured data. Be sure to
follow each step in order to achieve a better
understanding of how the Dash 10 works.
HOW TO
Every action step needed is listed in this column. Menu keys are listed in bold letter enclo sed by
brackets. For example,
[SYS]
is the black System key to the left of the display.
For parameters that have many choices available, the Dash 10 uses an encoder wheel that you
turn to make your selection. As you rotate the encoder wheel, you will see the value of the
parameter changes in the display. In this exercise, the encoder wheel values that you will select
are listed in bold font.

Select Chart with Channel 1
[MODE] [CHART 1]
Set speed to 5 mm/sec
[5] [SEC]
Common speeds have dedicated keys on front panel of Dash 10.
Stop the chart paper
[RUN / HALT]
Set Channel #1 to be 0 – 11 Volts FS
[Z/G]
Turn encoder wheel to Channel
1
.
[RANGE]
Turn encoder wheel until range is set to
11
Volts.
[ZERO]
Turn encoder wheel until Zero Position =
-50%
.
Run the chart
[RUN / HALT]
Input battery voltage into Channel # 1
Input signal into red and black banana jacks for Channel #1. Observe the signal
deflection goes from baseline on the bottom of the chart to near the top.
Stop the chart paper
[RUN / HALT]
Remove battery voltage
Proceed to the next page to set up data capture.
