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 “
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.
