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

ºC
, 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 "
