Chapter 2 Prepare for Use This chapter includes the following contents: ● ● ● ● ● General Inspecting Power-On Inspecting Connect the Probe Probe Compensation Auto Setting Service Manual
General Inspecting After receiving a new SDS1000D series oscilloscope, please inspect the instrument as follows: 1． ．Inspect the shipping container for damage. Keep the damaged shipping container or cushioning material until the contents of the shipment have been checked for completeness and the instrument has been checked mechanically and electrically. 2． ．Inspect the whole instrument.
Power-On Inspection Normal operating voltage for DS1000CA series digital oscilloscope is the range of 100-240VRMS with the frequency from 45Hz to 440Hz. Connect one terminal of the power cord to the socket in left side of the oscilloscope and the other to the power source. Picture 2-1 Connect power line Press the button on top of oscilloscope, some keys on the front panel will be lighted for about 6 seconds until the normal display appears. And then you can operate the oscilloscope.
Probe Compensation You are suggested to compensate probe before first using so as to match it to the input channel. Measurement error may generate without the compensation or because of deviation compensation. To compensate the probe, follow the steps below. 1．Set the probe option attenuation in the channel menu to 10X. Set the switch to 10X on the probe.
Auto Setup SDS1000D Series Digital Storage Oscilloscopes have auto setup function, which can identify the type of waveform and adjust controls to produce a usable display of the input signal. AUTO is the auto setup button. Table2-1 Auto setup function menu: Option （Multi-cycle sine） Introduction Auto set the screen and display several cycle signal. Set the screen and auto display single cycle signal. （Single-cycle sine） Auto set and show the rising time. （Rising edge） Auto set and show the falling time.
