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".

U.start

U.end

U.step

t.step

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.
