2.14.1. Update Firmware
This series of oscilloscope can upgrade the software by the USB flash disc, which needs about 5
minutes.
The firmware is upgraded by the following steps:
1. Plug the USB flash disc in which a firmware program is saved in USB Host interface on the front panel
of the oscilloscope.
2. Press [Utility] button to skip to the Utility menu.
3. Press Update -> Update Firmware softkey.
4. Select the file and press Multifunctional Knob to confirm. Then press Start updating softkey to
update the firmware.
5. Reboot the machine after finishing upgrading, and the software version is upgraded. The oscilloscope
should be self-corrected once after upgrading.
2.14.2. Self Calibration
The self calibration routine helps optimize the oscilloscope signal path for maximum measurement
accuracy. You can run the routine at any time but should always run it if the ambient temperature
changes by 5℃ or more. For a more accurate calibration, please power on the oscilloscope and wait
for 20 minutes until it has adequately warmed up.
To compensate the signal path, disconnect any probes or cables from the front-panel input connectors.
Then, push the [Utility] button, select Calibrate option and follow the directions on the screen.
2.14.3. Pass/Fail
“Pass/Fail” is used for judging whether the input signal is in a built rule range and outputting the past or
failed waveform so as to detect the change condition of the signal.
