<Set> Send current parameters immediately to the
871 Advanced Bioscan. Parameters are not
stored in the system file (
*.smt ) as long as
the file is not saved.
Pulse mode
This subtab of the Method parameters tab in the 871 Advanced Bio-
scan window contains the method parameters for the Pulse
mode. These values are sent and applied to the 871 Advanced
Bioscan by
Start determination and Startup hardware , or if the val-
ues are sent manually with <Set> .
Startup values
E1, E2, E3 Definition of three different working poten-
tials, which are applied to the amperometric
detector cell cyclically. The set potentials
are graphically displayed if the
Method op-
tion is enabled above the graphic window.
Range:
-2 ... +2 V .
t1, t2, t3 Time duration to apply the working poten-
tial.
Range:
0.1 ... 2 s (t1) , 0.01 … 2 s (t2,t3)
