Getting Started
To power-on the
oscilloscope
1 Connect the power cord to the rear of the oscilloscope, then to a suitable AC
voltage source. Route the power cord so the oscilloscope's feet and legs do not
pinch the cord.
2 The oscilloscope automatically adjusts for input line voltages in the range 100
to 240 VAC. The line cord provided is matched to the country of origin.
3 Press the power switch.
The power switch is located on the lower left corner of the front panel. The
oscilloscope will perform a self-test and will be operational in a few seconds.
Connect Probes to the Oscilloscope
1 Connect the oscilloscope probe to an oscilloscope channel BNC connector.
2 Connect the probe's retractable hook tip to the point of interest on the circuit or
device under test. Be sure to connect the probe ground lead to a ground point
on the circuit.
WARNING
Always use a grounded power cord. Do not defeat the power cord ground.
CAUTION
Maximum input voltage at analog inputs
135 Vrms
50
Ω input: 5 Vrms Input protection is enabled in 50 Ω mode and the 50 Ω load will
disconnect if greater than 5 Vrms is detected. However the inputs could still be damaged,
depending on the time constant of the signal. The 50
Ω
input protection only functions
when the oscilloscope is powered on.
CAUTION
When measuring voltages over 30 V, use a 10:1 probe.
