Parameter Range; Default value / Meaning
Soln.name 8 characters;
Name of the standard addition solution
The name of the standard addition solution must be identical to the
name entered on the "SUBSTANCES/Calibration" page under
Soln.name (see section 5.6.3). The mass concentration of the standard
addition solution Mass conc. must also be entered on this page.
V.add 0.010...50.000 mL; 0.100 mL
Solution volume that has been added
Volume of the standard addition solution that has been added to the
measuring vessel.
Description The ADD/M instruction is needed when a standard addition solution
should be added automatically using a dosing unit (e.g. 665 Dosimat or
725 Dosimat) which, in contrast to the 685 Dosimat or 700 Dosino, can
not be directly controlled by the 746 VA Trace Analyzer. In this case, the
addition must be initiated via the RS232 interface (using the
SEND>RS#
instructions) or via the remote interface (using the SETCTRL instructions)
and then confirmed with the ADD/M instruction.
Comments • The ADD/M instruction must be located within an ADD loop.
• In the last execution of the ADD loop, the ADD/M instruction is no
longer executed.
• The ADD/M instruction can not be used in operation with the 695
Autosampler.
