Purposes
a) Firstly, select the "Recorder" mode using the button on the top left of the front of the instrument, then
calibrate vertical sensitivity to 500mV/div and the recording duration to 2s, meaning one sample every 40µs.
You may notice that beneath the trace window, the time axis is graded in hours/minutes/seconds.
b) Then select the "Source/level" option from the Trigger menu, set the parameter as indicated below and press
the RUN/STOP button on the front to launch acquisition.
In the right hand image, we see that a fault has been detected and captured because the higher threshold
viewed on the right part of the screen has been crossed.
c) Using the "File Capture" option in the "Trigger" menu, we can detect and capture a whole sequence of faults
and the instrument automatically stores the acquisitions in its memory (up to 510). In the following example we
shall see how to sort and visualise them for analysis.

no. 12 : Recorder - 5 signals

Type Set of 5 slow signals with varied forms and characteristics
Duration of each signal ≈ 1s, amplitude 1.5V < Vpp < 3.5V
Sample length 2s - 40µs - MAIN = 500 mV/div DC coupling
None at first, then threshold(s) on MAIN, level depending on the signal
"Source/level" triggering, then "File Capture"
Basic presentation of "Record" mode
Observation of faults using two thresholds ("normal" and "File Capture" modes)
In the example given here, it runs from 14h39mn48s to 14h39mn50s
which indeed corresponds to 2s of recording duration.
In addition, 2 vertical cursors, one a dashed line (positioned here at the
instant of triggering) and the other a full line (completely on the right of
the screen) enable us to take two amplitude measurements over four
channels simultaneously.
In the example, these are respectively 1.700V and 1.661V on CH1.
