2)Connect the probe tip and reference lead to the generator output connector. Recommended input ~2V@1KHz peak-peak square wave. 3)Press the [Auto] button and you should see within a few seconds a square wave of about 2V peak-to-peak at 1KHz in the display. Repeat the steps to observe CH2. Probe Check Safety When using the probe, keep your fingers behind the guard on the probe body to avoid electric shock. Do not touch metallic portions of the probe head while it is connected to a voltage source. Connect the probe to the oscilloscope and connect the ground terminal to ground before you start any measurements.
Manual Probe Compensation Upon the first connection of a probe and an input channel, you should manually perform this adjustment to match the probe to the input channel. Uncompensated or miscompensated probes may lead to errors or faults in measurement. To adjust the probe compensation, follow the steps below. 1. Press Channel button to enter channel setting menu, Set the Probe option attenuation in the channel menu to 10X. Set the switch on the probe to 10X and connect the probe to Channel 1 on the oscilloscope. If you use the probe hook-tip, ensure it is firmly inserted onto the probe.
Attach the probe tip to the generator output connector, and connect the reference lead to the ground of the generator. The oscilloscope needs to set output signal as 2V @ 1KHz square wave. Press the [Auto] button. 2. Check the shape of the displayed waveform. Compensated correctly Overcompensated 3. If necessary, use a nonmetallic screwdriver to adjust the variable capacity of your Undercompensated probe until the shape of the waveform turns to be the same as the above figure. Repeat this step as necessary. See the figure below for the way of adjustment. 6
