Measure Trace 1 - 8: Avg
DC Voltage Standard Output Level: +1.0000V
7) Adjust the variable resistor (refer to Table 3.2 Adjustment point and Figure 3.7 Adjust-
ment point location diagram) corresponding to each channel so that the DC wave form
fits within 0 ± 20 mV as shown in Figure 3.8 Observed waveform.
8) Perform the adjustment of 7) for all channels.
