1 Description
Synchro output (at the back)
on Ø 4 mm sockets
The box consists of a voltage source, 4 resistances and 4 capacitors of
different values and a charging/discharging circuit controlled by a reversing
switch. The safety sockets at the terminals of the capacitor help study the
charging and discharging at constant voltage.
A synchro signal triggers the recording system (oscilloscope or ExAO) to
visualise the start of the charging of a capacitor.
The capacitor can be instantaneously discharged using the button located on
the rear face of the box.
The device is delivered with a safety jumper. To be completed with a 12 V
mains adaptor, Part no. 281 243.
