If a Dosimat Plus is used then a stirrer is normally also required. This is
then connected directly with the MSB connection of the 6.2148.010
Remote Box (stirrer: 801 or 802+804).
Please note that for the standard addition the mode “
DOS
” is set on
the Dosimat Plus. The activation pulse must be activated on the pH
Meter as well as the Dosimat Plus.
Furthermore, the Dosimat Plus
must be in the status
“HOLD”
. You can set the status to
“HOLD”
by
pressing the “Go” key once (check: the display of the Dosimat Plus
shows
“HOLD”
in the top right-hand corner).
