3 During the display period, the same options are available as at the end of a
normal test program. Select ‘Return’ from the ‘options menu' to take the
program back to the start of the first stage of a multiple test procedure to
enable further samples to be tested for the same parameters.
Note that some continuation test procedures involve a standing period. The
photometer may switch off automatically during this time. To avoid the
instrument switching off, use the timer function to time any standing period.
The timer will over-ride the auto switch off function.
