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:

perm: permanently switched on

off:

var:

switched on as required

Selection of the evaluation mode, here for

example , in the 3rd level of the main

menu.
