function.
1. Turn on the oscilloscope and warm-up for 20 minutes.
2. Connect the active probe to channel 1 of the oscilloscope.
3. Open the parameter bar of channel 1 and check the probe information,
including probe model, serial number, bandwidth, impedance, capacitance
and attenuation ratio.
4. Select the channel to which the probe is connected. Set the oscilloscope
scale factor to 1 V/div. Set the oscilloscope offset factor to 0 V.
5. Measure the average voltage of channel 1, and the reading range should
be within ± (1.5%* full-screen r10 mV). If the reading is beyond
the range, the check will not pass.
6. Change the scale factor of channel 1 to 500 mV/div, 200 mV/div, 100
mV/div, 50 mV/div, 20 mV/div, 10 mV/div, and repeat Step 5 to check the
average voltage reading at each scale.
