Description The FSWEEP instruction (Fast Sweep) starts the voltage sweep defined in
the parameters. During the sweep, the potentiostat always operates in
the operating mode "fast".

Comments • The electrode type must be defined before the FSWEEP instruction.
Admissible are DME , SMDE , HMDE or RDE .
• The measurement mode must be defined before the FSWEEP
instruction. Admissible are DCTMODE , DPMODE , AC1MODE , AC2MODE or
SQWMODE , but not PSAMODE or CYCMODE .
• The use of the FSWEEP instruction is practical only with the measure-
ment modes DPMODE and SQWMODE . With the other allowable meas-
urement modes, FSWEEP is identical to SWEEP .
• The FSWEEP instruction should always be used instead of the SWEEP
instruction with adsorptive stripping techniques (e.g. Ni and Co with
DMG).
• With the FSWEEP instruction maximum 1000 measured values can be
recorded.
• Apart from the FSWEEP instruction, no other SWEEP instruction is
allowed in the same segment.
• If the final voltage U.end should not be switched off at the end of the
program, enter a suitable standby voltage U.standby in a ØMEAS
instruction.
