5.7.1 Positive 1MΩ DC Accuracy
Procedure
 Recall DC accuracy - 1 Mohm 2mv.lss or configure the DSO :
Panel Setups : Recall FROM DEFAULT SETUP
Channels Trace ON Channel 1, Channel 2, Channel 3 & Channel 4
Input Coupling : DC
1MΩ on all 4 Channels
Input offset : 0.0 mV on all 4 Channels
Input gain : from 2mV/div to 2 V/div. (see Table 6) on all 4 Ch
C1 Averaging : 5 sweeps
C2 Averaging : 5 sweeps
C3 Averaging : 5 sweeps
C4 Averaging : 5 sweeps
Trigger setup : Edge
Trigger on : Line
Mode : Auto
Time base : 1 µsec/div.
Channel use : 4
Change parameters
P1 : Measure mean of C1
P2 : Measure mean of C2
P3 : Measure mean of C3
P4 : Measure mean of C4
 For the low sensitivities: 2 mV through 20 mV/div., connect the test
equipment as shown in Figure 5-4.
