Step 1: Introduction
Step 2: Terms to Be Familiar With
Probe: a pointed metal tip for making electrical contact with a circuit element being checked.
Waveform: a usually graphic representation of the shape of a wave that indicates its characteristics.
Trigger: to initiate, actuate, or set off by a trigger.
Voltage: electric potential or potential difference expressed in volts.
Div: abbreviation for division. Used to define scale of screen, as in volts per division.
Frequency: the number of repetitions of a periodic process in a unit of time.
Cycle Time: The amount of time in seconds elapsed between start and end.
Duty Cycle: The time occupied by signal step expressed as a percentage of available time
Peak to Peak Voltage (Vpp): The difference between the max positive voltage and max negative voltage
RMS Voltage (Vrms): Root Mean Square Voltage, is a statistical measure of the magnitude of a varying quantity
Average Voltage: Average voltage value during a period of time
DC Voltage: Direct Current Voltage, is a steady current source that does not oscillate like that of an AC voltage source. DC voltage is usually produced by sources such as batteries.
Note: Definitions provided through Merriam-Webster and Wikipedia definitions.
Step 3: Components and Buttons
LCD Screen: 2.8” TFT LCD screen. Displays current settings and signals.
Adjust Up: Adjust selection up.
Adjust Down: Adjust selection down.
Confirm/Mode: Used to adjust signal display options and confirm selection.
Menu Clockwise: Adjust selection left. Mainly used to select menu option.
Menu Counter Clockwise: Adjust selection right. Mainly used to select menu option.
Quick Adjust: Quickly automatically adjusts to best-fit view for current signal.
Run/Stop: Run/Pause signal reading for viewing specific components or saving an image.
Probe Jack: Input for signal viewing.
Mini USB Port: USB port for viewing stored images and charging device.
Signal Generator: Output for internal signal generator.
TF Card Slot: SD Card slow for mini SD card. Used to store image captures.
Step 4: User Interface
Vertical Scale: Adjust to change voltage/division scale on screen (voltage height on screen). Each division is one grid unit of the screen.
Time Base: Adjust to change horizontal scale (time width on screen) Each division is one grid unit of the screen.
Y Position: Adjust Y Position marker to move the waveform up and down.
Trigger Type: Displays current triggering type. Default is on the signals rising edge (↑S)
Probe Attenuation Scale: This is a probe multiplier. Used for amplifying signals before being read on the display. You can select either x1 or x10.
Save Waveform: Select to store waveform to the inserted SD card.
Load Waveform: Select to load waveform from the inserted SD card.
Ref. Square Wave Frequency: Use to adjust the frequency of the square wave using in the frequency generator.
Time Marker 1: Marker 1 used to fine tune precise measurements. Place on one side of signal (opposite of Time Marker 2) to get more accurate readings
Time Marker 2: Marker 2 used to fine tune precise measurements. Place on one side of signal (opposite of Time Marker 1) to get more accurate readings
Horizontal Position Adj.: Use to adjust signal position left or right. Useful when a specific part of the signal is needed for better viewing.
Voltage Measure: Displays the voltage difference between Voltage Marker 1 and Voltage Marker 2. Time Measure: Displays time at Time Marker 1
Status: Displays current status (RUN, HOLD)
WAVEFORM & MARKERS
Current Waveform: Beginning point of current input.
Trigger Level Marker: Displays voltage level for when trigger will be activated. Select Trigger Level window to adjust marker.
Reference Waveform: Beginning point of reference waveform.
Y Position Marker: The Y Position Marker indicates zero volts for referencing a signal to.
Voltage Marker V2: Reference level 2 for Voltage Measure. Select V2 in Voltage Measure window to adjust position.
Step 5: Triggering Waveforms
NORM – Displays synchronized waveforms
SING – Displays triggered waveform and holds
SCAN – Continuously sweeps waveform from left to right
NONE – Refreshes unsynchronized waveform, ignores trigger
FIT – Automatically adjusts vertical and horizontal scale to fit waveform
Step 6: USING IT!
1. Turn your device on by sliding the power switch to the on position. You should see a boot-up screen with general information followed by the main screen. If your device does not power on your battery may be dead.
2. Insert the connection probes into the Probe Jack located on the side of the device.
3. Connect the probes to the point of the circuit you would like to test. Black is connected to ground and red/white is connected to the test point.
4. You should now see your device measuring the signal on the main screen. You may need to adjust the horizontal or vertical scales to get a better view or use the Auto Scale feature.
5. Use the left and right arrows to move to the auto measure window.
6. Use the up and down arrows to change the current measurement to Vpp and select OK
7. The peak to peak voltage will now be visible in the auto measurement window.
Step 7: Saving an Image to the SD Card
I've also saved a rar file here that contains the first 39 FILEXXX.DAT files here.
Step 8: Signal Generator
Step 9: WARNING!
1. Always be careful when working with electronics and circuitry.
2. Always remove power source when touching components of circuit.
3. Be careful when applying probes to circuit not to short any parts of the circuit.
4. Do not apply more than 80 Volts peak to peak to the input of the oscilloscope. Be careful when using attenuation probes (if on x10, only 8 Volts peal to peak can be applied).
