(8) Set oscilloscope calibrator for a CHAN 1, VOLTAGE mode output of 10 mV at 1
kHz frequency and set TI CH 1 VOLTS/DIV switch to 2 mV.
(9) Pull SEC/DIV knob out and press A/B TRIG pushbutton for B TRIGGER and
push TRIGGER MODE down for TRIG AFT DLY. Adjust TRIGGER LEVEL for a
stable display.
(10) Adjust ΔREF OR DLY POS control for a delay readout of 0.000 ms.
(11) Adjust TRIGGER LEVEL control for most positive voltage that produces an
intensified point on waveform display for both + and - SLOPE. If B TRIGGER level
readout indication is not within limits specified in + peak column of table 7 for 2 mV
setting, perform b below.
(12) Adjust TRIGGER LEVEL control for most negative voltage that produces an
intensified point on waveform display for both + and - SLOPE. If B TRIGGER level
readout indication is not within limits specified in - peak column of table 7 for 2 mV setting,
perform b below.
(13) Repeat technique of (8) and (10) through (12) above for each remaining
VOLTS/DIV switch setting and oscilloscope calibrator output listed in table 7.
