Press the button to pull up the auto-measure engine. You can select up to multiple parameters simultaneously to display at the bottom of the screen.
The interface of the DOS1102 is divided into distinct functional zones. Mastering these physical controls is key to efficient troubleshooting. The Display Zone
This controls the time-base. The manual details:
If you need help troubleshooting a specific signal issue, let me know:
Access Input Coupling (AC/DC/GND), Probe Attenuation (1X/10X), and Inversion settings. 4.2 Horizontal System Settings hanmatek dos1102 manual
The scope waits until the trigger condition occurs exactly once, captures that moment, and freezes the display ( STOP mode). This is ideal for catching turn-on voltage spikes, transient glitches, or digital startup sequences. Setting up an Edge Trigger Press the TRIG MENU button. Set Type to Edge . Set Source to CH1 (or whichever channel holds your signal).
Rotating clockwise reduces the volts/div (magnifies the signal), counter-clockwise increases it.
: Ensure your probe ground lead is securely attached to a clean grounding point close to the signal source. To help tailor this guide further, let me know: Are you troubleshooting a specific error or a blank screen ?

The Hanmatek DOS1102 eliminates manual grid-counting by offering automated measurement tools. Automated Measurements Press the button. Select your source channel (CH1 or CH2).
Controls the time base (sec/div) and horizontal position.
The Hanmatek DOS1102 is a highly popular, budget-friendly digital storage oscilloscope (DSO). It features a 110 MHz bandwidth, 2 channels, and a 7-inch TFT color display.
: The most common mode. It triggers when the voltage crosses a set threshold. Mastering these physical controls is key to efficient
Select the function to convert time-domain signals into frequency-domain components. This is ideal for finding noise and distortion frequencies. Trigger Modes
Choose DC (passes all signals), AC (blocks DC offsets to look at ripples), or GND (disconnects input to show zero-volt reference line).
The oscilloscope continuously updates the screen even if no trigger criteria are met. Use this when you are hunting for a lost signal or measuring flat DC lines.
