Figure 1 Connect power cord Note: To avoid electric shock, make sure that the instrument is correctly grounded to the earth before connecting AC power. Press the power-on button located at the lower left corner of the front panel and note that several oscilloscope keys will be lighted for about 6 seconds simultaneously, until the boot screen appears. The oscilloscope will then begin to perform its power-on tests automatically, after which the DEFAULT SETUP button can be pressed in order to recall the factory default settings.

Probe Compensation It is necessary to compensate the probe at first use so as to properly match the probe to the oscilloscope‟s input channel. Non-compensated or poorly compensated probes may cause measurement inaccuracies or errors. The probe compensation steps are as follows: 1. Set the attenuation switch on the probe to 10X. Figure 2 Set the attenuation switch 2. Connect the alligator clip of the probe to the Ground Terminal on the front panel, and then use the probe to connect CH1 BNC input connector to the Compensation Signal Output Terminal. Compensation Terminal Ground Terminal 3....

Press the Auto Setup) key to enable the waveform auto setting function. The oscilloscope will automatically adjust the horizontal time base, vertical scale and trigger mode according to the input signal to obtain an optimum waveform display. Table 2 Auto setting menu • The input signal frequency must be higher than 20 Hz, with the amplitude greater than 8 mV. • Select the channel with the lowest frequency when several channels are connected to signals.

Self Calibration The self-calibration routine can quickly adjust the oscilloscope to perform at the optimum state in order to achieve the maximum accuracy. Self-calibration can be performed at any time, especially when a change in the ambient temperature of 5°C or more has occurred. Make certain that the oscilloscope has been warmed up or operated for more than 30 minutes before performing the self-calibration. Use the following steps to perform self calibration: 1. Disconnect all leads from all input channels. 2. Press the |Utility| button on the front panel, and then press the Do Self...
