2.1
Power on
Before powering on the 4456 series digital phosphor oscilloscope, please check the power supply unit according
to the
“
Power supply requirements
”
in Chapter I. Power on the digital oscilloscope after confirming that power
supply is correct.
Instructions:
The safety of digital oscilloscope conforms to the requirements of
GJB3947A-2009: The effective AC rating is 1.5k v, 1 min, 10 mA, with no
flashover or breakdown; input voltage AC is 242 V, and leakage current is
≤
3.5
mA. Therefore, the operation and maintenance of the oscilloscope according to
the specified operation regulations will not cause personal hazard or injury or
cause any damage to the DUTs.
Press down the power button on the rear panel of the 4456 series digital phosphor oscilloscope, and the poweron
indicator lamp on the front panel of the oscilloscope will turn yellow. Press down the power button
