(28) Adjust ' control for a 't readout indication near 10.00 ns to superimpose the
two time markers. If 't readout indication is not within limits specified in first row of table
17 with the two time markers superimposed, perform b below.
(29) Repeat technique of (28) above for 't readout indications listed in table 17. If 't
readout indications are not within specified limits in table 17 with the two time markers
superimposed, perform b below.
