## .. SIMPULSE .....
Function
Simulation of standard additions with the 3.496.8380 VA Simulator.
Description
The
SIMPULSE
instruction is used to put out a total of 100 pulses at the
3.496.8380 VA Simulator which cause an increase in the current
measurement and hence a simulation of standard additions. The VA
Simulator can be reset to the original current level with the
SIMRESET
instruction.
Comments
•
The 3.496.8380 VA Simulator and the associated 3.496.5190
Connecting cable are available as an option. The VA Simulator gen-
erates 2 polarographic current waves with half-wave potentials of ca.
–540 mV and ca. –1070 mV in a defined voltage range. You will find
further details in the 3.496.8380-SB Circuit Description supplied with
the VA Simulator.
•
To obtain a larger current increase, the
SIMPULSE
instruction can also
be entered twice in succession.
