4. Iterate steps 2 and 3 until the value for T1 converges.
Deadtime measurements are made at both high and moderate light intensity levels by using
two different neutral-density filter settings (positions 0, 1 for Filterwheel #2); five
measurements are taken at the higher intensity, ten at the lower intensity.
Method:
The command DT is issued.
Following the usual five minute lamp warm-up, and a further 10 minutes for test to run, results will
be printed in a format similar to the following:
