| 説明 | Interestingly the oscilloscope kit instructions have you solder the power-side components then check your work -- probe "TP5" looking for 5V. If all is good then you bridge "JP1" to send power to the digital side.When I checked the voltage I did not get 5V. This caused some anxiety, a careful re-checking of the instructions and close examination of the solder joints.When I attempted to measure TP5 again I discovered that this lead on my digital multi-meter probe had broken cleanly away! Several years of flexing had finally broken the multi-strand cable where it joins the probe (but was still held in place by the probe's sleeve). Fortunately I had a spare DMM and found 5V at the test point -- OK to continue! |
