3.2 Standardization of luminescence measurements relative to 100
(relV)
If this option is selected, all values measured during the luminescent bacteria test (GL,
EC, LU, etc.) are standardized relative to the first measurement obtained in the test.
The first measurement is set to 100, and all subsequent measurements are calculated
and expressed relative to this measurement. This is the usual international convention
for the luminescent bacteria test, but poorly luminescent bacteria suspensions are not
recognized, e.g. after superimposition.
Select option for standardization of
measured values relative to 100:
relV current standardization setting
perm: permanently switched on
off: switched off
var: switched on as required
Selection of the evaluation mode, here for
example <LU>, in the 3rd level of the main
menu.
