The set values of the probe switch are 1X and 10X (see Figure 3- 7).
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
The safety guard ring around the probe body protects your finger against
any electric shock, shown as Figure 3- 8.
Warning:
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 conduct self-calibration
Self-calibration program is used to quickly make the oscilloscope be in the
optimum condition to obtain the most accurate measurement. This program
can be performed at any time. It is especially necessary when the ambient
temperature reaches or exceeds 5℃.
To conduct self-calibration, disconnect all probes and wires from the input
connector. Then, press Settings key at the oscilloscope area of the front
panel or click "
from the right menu and Self-calibration from the menu displayed, and
click Start in the self-calibration display box.
