Comments

The electrode type must be defined before the

TSWEEP

instruction.

Only

HMDE

or

RDE

are admissible.

The measurement mode must be defined before the

TSWEEP

instruction. Admissible are

DCTMODE

,

DPMODE

,

AC1MODE

,

AC2MODE

or

SQWMODE

, but not

PSAMODE

or

CYCMODE

.

Apart from the

TSWEEP

instruction, no other SWEEP instruction is

allowed in the same segment.

If the current measurement should be performed without measured
value recording, the

TSWEEP

instruction must be replaced by the

MEAS

instruction. In contrast to

TSWEEP

, this may be in the same

segment as the measurement sweep.

If the measurement voltage

U.meas

should not be switched off at the

end of the program, enter a suitable standby voltage

U.standby

in a

ØMEAS

instruction.

Maximum 1000 measured values can be recorded in a segment. The
number of measured values is calculated as follows:

Measurement duration

t/s

Number of measured values = –––––––––––––––––––––––––

Time interval

t.step
