Service manual

displays an "adjustment complete" message. If a calibration error occurs,
the program displays the calibration error and prompts you to repeat the
adjustment (see Table 5-1 for a list of calibration errors).
When connected to the Agilent E1326B multimeter, some DC
Standards may exhibit voltage variations at the start of a measurement.
TRIG:DEL .05 (line 190) adds a 0.8 second wait before calibration
begins to allow settling time for the DC Standard output. TRIG:DEL
.05 is used since the input is sampled 16 times before the calibration is
performed. Thus, total added delay = 0.05 seconds x 16 = 0.8 second.
