(4) Rotate oscilloscope calibrator knob located below EDIT FIELD button to align
one time marker per division over center 8 divisions of oscilloscope display. If oscilloscope
calibrator err readout indication is not within +2.5 percent, perform b (1) below.
(5) Set TI TIME/DIV switch to 10 s and oscilloscope calibrator MARKER output
to 10 s.
(6) Repeat technique of (3) and (4) above, except, if oscilloscope calibrator err
readout indication is not within 1.5 percent, perform b (2) below.
(7) Set TI TIME/DIV switch to 10 ms and oscilloscope calibrator MARKER output
to 10 ms.
(8) Repeat technique of (3) and (4) above, except, if oscilloscope calibrator err
readout indication is not within 1.5 percent, perform b (3) below.
(9) Repeat technique of (3) and (4) above and set oscilloscope calibrator MARKER
output and TI TIME/DIV switch settings as listed in table 3. At each setting, oscilloscope
calibrator will display one time marker per division between second and 10th vertical
graticule line within percent of error listed in table 3.
