Power Consumption
Maximum power consumption with all accessories installed (e.g., active probes, USB peripherals, digital
leadset) is 150 W (150 VA) for four-channel models and 100 W (100 VA) for two-channel models. Power
consumption in standby mode is 4 W.
Ground
The AC inlet ground is connected directly to the frame of the instrument. For adequate protection again
electric shock, connect to a mating outlet with a safety ground contact.
WARNING. Only use the power cord provided with your instrument. Interrupting the protective
conductor inside or outside the oscilloscope, or disconnecting the safety ground terminal, creates
a hazardous situation. Intentional interruption is prohibited.
Fuse Replacement
Disconnect the power cord before inspecting or replacing the fuse. Open the fuse holder (located at the rear
of the instrument below the AC power inlet) using a small, flat-bladed screwdriver. Replace the old fuse with
a new 5 x 20 mm T-rated 3 A/250 V fuse. Close the fuse holder before powering on.
WARNING. For continued fire protection at all line voltages, replace the fuse with one of the
specified type and rating only. Always disconnect the power cord before replacing the fuse.
