Note:
1. Backlight time and automatic shutdown time will not be executed when the os-
cilloscope is plugged in with an external charging device or connected to a comput-
er via a USB cable.
2. Shutdown automatically saves last setup.
Self calibration
The self calibration routine helps optimize the oscilloscope signal path for maxi-
mum measurement accuracy. You can run the routine at any time but should al-
ways run it if the ambient temperature changes by 5°C or more. For a more accu-
rate calibration, please power on the oscilloscope and wait for 20 minutes until it
has adequately warmed up.
To do self calibration, follow these steps:
1. Ensure that no input signal is input, otherwise it may damage the instrument.
2. Press Menu button to select the self calibration function.
