Setting Up a Miniature Electronics Lab CH 2
The oscilloscope you will find in the kit is called Zoolark, which is a
miniature device that has multiple functions integrated into it. Zoolark is
significantly less expensive than industrial oscilloscopes yet it still allows
you to perform basic waveform scoping and measurements.
To use Zoolark as an oscilloscope, you need to set it to waveform scoping
mode. Use Channel 1 (CH1) and/or CH2 to probe the signal to be
measured. All four ground pins on Zoolark are internally shorted so you
can use them interchangeably.
While measuring the signal, you need to adjust the time/div and voltage/
div to appropriate scale. If the signal being measured is a periodic AC
signal, we recommend to set the time such that 2-3 complete cycles can
be displayed in the screen. For example, if you use a wire to short WAV
and CH1 as indicated, you should observe a sine wave on the screen.
Adjust the time setting until only 2 cycles are displayed in the screen, and
you should see the measurements are getting more stable.
