The
transient recorder is the ideal instrument for measuring slowly
changing signals like the temperature change in a room or the
movement of objects. The transient recorder is a direct recording
instrument. This means that each measured sample is displayed
immediately. An oscilloscope first has to fill a complete record and
then displays the record, resulting in long waiting times when a slow
sampling speed is selected
The
transient recorder can sample with sample times between 0.01 sec and
500 sec. The maximum number of samples is 32760/65520/131060
(depending on the instrument), resulting in a maximum measurement
time of almost 190/380/758 days.
While
measuring, each sample is displayed in one display pixel. When the
number of samples is larger than the display width, two different
methods can be used to display the next sample: scan mode and roll
mode. With scan mode, the screen is cleared and filled again from
left to right. With roll mode the trace will shift through the
display from right to left.
Apart
from the features mentioned above, the transient recorder is quite
the same as the oscilloscope:
The
extensive possibilities of the cursors can be used to analyze the
measured signal. Besides the standard measurements, also True RMS ,
Peak-Peak, Mean, Max and Min values of the measured signal are available.
An
AUTO DISK function is available which can capture unexpected
disturbances. When the instrument is set up for the disturbance, the
AUTO DISK function can be started. Each time the disturbance occurs,
it is measured and the measured data is stored on disk. When pre
samples are selected, both samples before and after the moment of
disturbance are stored.
