CAUTION:
When the attenuation switch is set to 1X, the probe will limit the
bandwidth of the oscilloscope in 5MHz. To use the full bandwidth of
the oscilloscope, the switch must be set to 10X.
How to Use the Probe Safely
2.7
The safety guard ring around the probe body protects your finger against any
electric shock, shown as Figure 11.
CAUTION:
To avoid electric shock, always keep your finger behind the safety guard
ring of the probe during the operation. To protect you from suffering
from the electric shock, do not touch any metal part of the probe tip
when it is connected to the power supply. Before making any
measurements, always connect the probe to the instrument and connect
the ground terminal to the earth.

How to Implement Self-calibration
The self-calibration application can make the oscilloscope reach the optimum
condition rapidly to obtain the most accurate measurement value. You can carry
out this application program at any time. This program must be executed
whenever the change of ambient temperature is 5 ºC or over.
Before performing a self-calibration, disconnect all probes or wires from the input
connector. Press the "Utility" button, then, press H1 button to call out the
Function menu; turn the M knob to choose Adjust. Press H2 button to choose
the option "Self Cal"; run the program after everything is ready.
