1.4 Functional Check
Follow the steps below to perform a quick functional check to your oscilloscope.
1.4.1 Connect the oscilloscope
Set the switch on the probe to 10X and connect the probe to Channel 1 on the
oscilloscope. First, align the slot in the probe connector with the protuberance on the
CH1 BNC and push to connect; then, turn to right to lock the probe in place; after that,
connect the probe tip and reference lead to the PROBE COMP connectors. There is a
mark on the panel: Probe COMP ~2V@1KHz.
1.4.2 Observe the waveform
Press the [Auto Scale] button and you should see within a few seconds a square wave
of about 2V peak-to-peak at 1KHz in the display. Press the CH1 MENU button twice to
remove Channel 1. Push the CH2 MENU button and repeat the steps to observe CH2,
CH3 and CH4.
