Note: When the attenuation switch is set to 1X, the probe will limit the bandwidth
of the oscilloscope in 5MHz. If it is needed to use the whole 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 the electric
shock, shown as Fig. 4-8.
Fig. 4-8 Finger Guard
Warning: In order to avoid suffering from the electric shock, please keep your
finger behind the safety guard ring of the probe body during the operation.
In order to protect you from suffering from the electric shock during your using the
probe, do not touch the metal part of the probe tip when the probe is connected to
the power supply.
Before making any measurements, please connect the probe to the instrument and connect the
ground terminal to the earth.
How to Implement Auto-calibration
The auto-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, but when the range of variation of the ambient
temperature is up to or over 5℃, this program must be executed.
For the performing of the self-calibration, all probes or wires should be disconnected
with the input connector first. Then, press the "8(UTILITY)" button to call out the
FUNCTION menu; push down the F3 menu selection button to choose the option "
Do Self Cal"; finally, run the program after confirming that everything is ready now.
Introduction to the Vertical System
Shown as Fig.4-9, there are a series of buttons and knobs in VERTICAL
CONTROLS. The following practices will gradually direct you to be familiar with
the using of the vertical setting.
