Fuses and Power Interruption
If power to the instrument fails or is turned off while the
instrument is running, turn the instrument off and wait five
minutes before restarting. If you do not wait, or if the power is
restored quickly after a power failure, a fuse may blow. This does
not mean that there is anything wrong with the instrument. It is
caused by the refrigeration motor stalling because it is unable to
start until the pressure bleeds away, which takes about five
minutes.
