5.2 POWERING DOWN
PIM31 can be powered down in different ways listed below. It is not
recommended to power down simply by “Pulling the plug” or
switching off the Main Switch on the back panel.
Exiting
The proper way is to Exit the UI is by pressing the
red exit button. This will generate an exit pop up.
Respond to the pop-up menu’s choice Yes / NO to
power the system down or not. This method ensures
the RF is switched off properly, all UI and computer
processes are terminated in an orderly fashion, and
data files are closed.
Forced Termination
Holding the Start Button on the front panel for 3 seconds generates a soft
reset. RF is switched off, and all vital files will be closed and stored. In
this mode, the urgency to power off the unit trumps handling and closing
all files. Some information, e.g. log data may be lost.
Main Switch
When not following the proper shutdown sequence and using the Main
switch on the back to terminate power it is likely that files get corrupted,
and the test system may be harmed.
Note: Cooling fans may become operational after the main switch is
placed in the off position until discharge of all internal capacitors is complete;
typically within 5 seconds
