## .. TSWEEP ..... U.meas ........mV
Function Application of a constant voltage to the electrodes and measurement of
the current with measured value storage.
Parameter Range; Default value / Meaning
t/s 0.1...999.9 s; -
Measurement duration
The duration of measurement is entered in the line time.
U.meas -3000...3000 mV; -
Measurement voltage
The voltage entered here is applied to the electrodes. This voltage is
retained even after the line time has elapsed until a SWEEP instruction
follows or until it is switched off by
ØMEAS or END in the main program
on the "OP.SEQUENCE" page.
Description The TSWEEP instruction is used to apply the voltage defined in the
U.meas parameter to the electrode and start the current measurement in
accordance with the parameters defined in the measurement mode. The
measurement frequency is determined by the time interval
t.step of the
measurement mode, the measurement duration by the line time of the
TSWEEP instruction.
In contrast to the MEAS instruction, the measured values in measurement
of the current are plotted. It is also possible to display the live curve (see
section 5.5.1), but no evaluation is performed.
