7-2 Attention to use：
a. Twisting the input leads as following helps to cancel noise that is
induced into the input leads and to improve the high frequency
response of the inputs.
b. Do not extend input cables if not necessary, this will lead to more
noise. If it is necessary to extend input cables, the extend cables length
should be same. And the measured signal frequency should be lower
than 10MHz. Otherwise the errors will be larger.
c. The probe and measuring instrument should warm up for 20 minutes if
want to get high accuracy measuring result.
7-3 Troubleshooting
The Power LED does
not remain lit
The
measured
waveform can't be
displayed right and
stability
Check that the AC adapter is plugged in and
functional.
Check that the probe accessories that you are
using are fully mated.
Check the probe connection on your circuit.
Perform a functional check on the probe.
Change a different channel on the oscilloscope
or change a different oscilloscope.
