The uScope –Getting started

Introduction (fw 4.19 October 1, 2011)

The uScope! A single channel, pocket-sized,

digital storage oscilloscope that ¡s small, quick,

and powerful. Automotive presets get you going

quickly. Ideal for the Flat Rater that wants the

ultimate run and gun lab scope for pin point

testing. Ideal for the student that is ready to

start scope'n.

The uScope is powered by an easy to use

interface enhanced with automotive presets and

reference waveforms.

Put the power of the uScope in your hand (and shirt

pocket).

Secondary ignition, injectors, mass air flow, crank,

cam, TPS, 02, CTS you name it it'll scope it. The

uScope is also perfect for your low amp probe,

secondary ignition pickup and pressure transducers.

When you just need to run a quick

test to verify the "signal" is working

as the engineer intended, why spend

time pulling out and setting up your

"big boy Scope" when you can do it

faster with the uScope?

AES uScope Manual

First Time Use:

Protective Film:

The uScope is shipped with a protective film over the screen and the backside of the unit. Please

feel free to remove the plastic film.

Charge the battery:

Charge your new uScope for at least 5 hours before first use.

CAUTIONS

Test Lead Connection

The test lead connects to the uScope via an audio plug. The signal rides on the tip of the audio plug.

If the tip of the test lead plug touches ground while the test lead is connected to a circuit, the circuit

will short.

oAlways connect your test lead to the uScope before connecting to a circuit.

oAlways disconnect from the circuit before disconnecting from the uScope.

Circuit Testing while Charging uScope

It is not recommended to connect the uScope input channel to a circuit while the uScope is charging.

Doing so may result in a ground loop that can destroy equipment and possibly endanger the user.

Intended for DC Circuits

The uScope is designed for use on DC circuits with a maximum voltage of 80 volts.

oDo not use the uScope for testing Line Voltage AC circuits.

oFor DC circuits above 80 volts use a 10x probe. Contact AESwave.com or more information.

Automotive Professionals

The uScope is intended for use by automotive professionals with adequate training.

oIf you are not sure, ask!

AES uScope Manual

Ports, Connection and On/Off Button

On/Off

The on off switch is located at the bottom right of the

unit. It is a slide switch.

Test Lead Port

The test lead connection is a 3.5mm stereo audio jack

located at the top left side of the unit. When connecting,

ensure that the plug is inserted to the base.

Note: The 3.5 stereo audio jack port located at the

bottom left of the unit is a signal generator. DO NOT USE

THIS PORT WHEN TESTING AN AUTOMOTIVE CIRCUIT.

USB to PC Connection and Charging Port

The USB connector is a standard micro USB and is

located in the middle left side of unit. This port is used

for PC and uScope communication and for charging the

uScope.

Memory Card –microSD Card

The uScope incorporates a microSD memory card. The

card port is located in the center of the bottom side of

the unit. Note that the electrical connection tabs face

toward you for installation. Press the card in until fully

seated. When properly installed the card will be just

below flush.

**Do not remove the memory card. Doing so may

disable the ability to save and recall setups.

AES uScope Manual

Quick Start - How To:

Charge the battery:

Charge your new uScope for at least 5 hours before first use.

Waveform Capture using a PreSet:

All presets are stored and loaded onto the SD card.

Turn on the uScope by sliding the switch located on the bottom right of unit.

1. Use the UP | DOWN arrow keys and highlight the “PS”(PreSets) menu item.

2. Press “OK”and the menu will open.

3. Use the UP | DOWN arrow keys to highlight the desired preset “Group.”

a. Sensors, Actuators, Amp, Ignition, Charging, User Set Ups

4. Press the LEFT | RIGHT arrow keys to select the desired preset in the “Group“.

5. Press and Hold the “OK”button to activate the preset.

6. Connect your test leads and fine tune time voltage and trigger adjustments if desired.

7. Note: To select Auto Setup, highlight Auto Setup, and press & hold “OK” to activate it.

Waveform Capture not using a PreSet:

1. Turn on the uScope by sliding the switch located on the top right of unit to the right.

2. Use the UP | DOWN arrow keys and highlight the “Tr”(Trigger) menu item.

3. Press “OK”and the menu will open

4. Use the UP | DOWN arrow keys to highlight the “Tr”Mode (Trigger Display Mode) Menu item.

5. Use the LEFT | RIGHT arrow keys to select AUTO. Note the prompt located in the top left of the

screen.

a. AUTO trigger type will allow the uScope to update the screen regardless of other trigger

settings. This is a great first step to get the signal on the display. Reference chart on

page 11.

6. Press “OK”to exit the menu

7. Connct test leads to the signal.

8. If the signal is to short or too tall:

a. Use the UP | DOWN arrow keys and highlight the “.V”menu item.

b. Press “OK”and the menu will open

c. Use the UP | DOWN arrow keys and highlight “V/Div”

d. Use the RIGHT arrow key to make the waveform taller. Use the LEFT arrow key to make

it shorter.

e. Press “OK”to exit the menu

Continued….

AES uScope Manual

9. To see more of the signal or less of the signal:

a. Use the UP | DOWN arrow keys and highlight the “.T”(Time Settings) menu item.

b. Press “OK”and the menu will open

c. Use the UP | DOWN arrow keys and highlight “T/Div”

d. Use the RIGHT arrow key to go to a faster time setting showing less time of the signal but

in greater detail –like a magnifying glass. For example, see one injector pulse instead of

three.

e. Use the LEFT arrow key to go to a slower time setting showing more time of the signal

but in less detail. For example, display three injector pulses instead of one.

f. Press “OK”to exit the menu

10. To stablize the signal:

a. Some signals can not be stablized. For example, a square wave that has a unique ID

such as a crank sensor. Other signals are easy to stabalize. In either case follow these

procedures:

b. Use the UP | DOWN arrow keys and highlight the “Tr”(Trigger Settings) menu item.

c. Press “OK”and the menu will open.

d. Use the UP | DOWN arrow keys to highlight the “Tr” Level (Trigger voltage level) Menu

item.

e. Use the LEFT | RIGHT arrow keys to set the trigger level. The LEFT arrow key moves

the trigger level down and the RIGHT key moves the trigger level up. Note: the Yellow

dotted horizontall line in the display indicating the selected level.

f. Note: When “Tr”level menu item is selected, The numerical value of the Trigger will be

displayed on the top right of the screen.

g. A good technique for beginners is to move the Yellow Dotted line level indicator above

the signal. Then move it down and note the changes in the display of the waveform.

i. Rules of thumb:

1. For repetitive signals that do not have a unique spike that reaches above

or below the repetitive portion of the signal, such as a square wave, just

place the trigger level within the center 1/3 of the signal. Leave the

TRIGGER MODE on AUTO or NORM.

2. For signals that do have a unique charactoristic such as an injector or

ignition place the TRIGGER LEVEL along a unique portion of the signal

such as the rising edge of the spike or a falling edge use TRIGGER

MODE on NORM to stabalize. One more helpful adjustment is to set the

TRIGGER SLOPE to positive or negative. (In the “TR”menu highlight

“TR.”SLOPE and use the LEFT | RIGHT arrow key to set the SLOPE.
