DPO6000, MPO6000 Series Digital Fluorescent Oscilloscope Product Manual V1.3 2. Connect the probe ground alligator clip or ground spring to the circuit ground termi- nal, and then connect the probe to the circuit under test. Connect the logic probe: 1. Connect one end of the digital probe to the digital channel input interface on the front panel of the oscilloscope (the digital probe has no direction). 2. Connect the other end of the digital probe to the signal under test. The MPO6000 se- ries comes standard with four LP104 digital probes. Check the probe voltage Each time you connect a probe to an input channel, you should perform a probe check.
Use the "Vertical Menu" button; for example, press the CH1 menu button to set the probe attenuation coefficient. Manual probe compensation When connecting the probe to any input channel for the first time, make this adjustment to match the probe to the input channel. Uncompensated or compensated probes can cause measurement errors or errors. To adjust the probe compensation, follow these steps: 1. Set the probe option attenuation to 10X in the Channel Menu. Set the switch on the probe to 10X and connect the probe to channel 1 of the oscilloscope. If using the probe hook end, make sure that the hook end is firmly seated on the probe. Connect the probe tip to the probe element:
~ 2V @ 1K Hz connector, and connect the reference wire to the "probe element ground" connector, then press the "Auto Scale" button. 2. Check the shape of the displayed waveform Compensated correctly Overcompensated Undercompensated 3. If necessary, use a non-metallic screwdriver to adjust the variable capacitance on the probe until the waveform shown on the screen is "compensated correctly" as shown above. Repeat this step if necessary. The adjustment method is shown in the figure be- low. 11
