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 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℃ or over.
Before performing a self-calibration, disconnect all probes or wires from the input
connector. Press the "Utility" button, select Calibrate in the left menu, select Self
Calibrate in the bottom menu. A confirmation window will pop up, select OK after
everything is ready.
