GETTING STARTED

Step 6 Press the ANALOG key to enter the digital mode

Step 7 Press the top one (mV) of the AMPL keys, so that the signal has maximum amplitude.

Press AUTO RANGE and see the signal change to a suitable attenuator value. When AUTO RANGE is active, the attenuators automatically adjust when the signal amplitude changes, to keep the trace on screen.

Step 8 Press the key labeled AVERAGE. Noise in the input signal can be reduced by using the average function. The random noise is reduced by calculating the average over the last n scans (average factor can be set between 2 and 4096)

NOTE: Refer to Chapter 4 for an explanation of the CH1+CH2, TRIG1, and INV keys.
