5. Set the voltage source to 0 V.
6. CHECK that the horizontal CURSOR readout is within the limits shown in
Table 5–7 for a voltage source of 0.000 V at each setting of HORIZONTAL
VOLTS/DIV STEP GEN.
7. Set HORIZONTAL to 200 mV/DIV STEP GEN.
8. Repeat Step 6, this time setting the voltage source to the non zero – value
shown in table 5–7 for each setting of HORIZONTAL VOLTS /DIV
STEPGEN.
9. CHECK that the horizontal CURSOR readout is within the limits shown in
table 5–7.
