Caution
Do not use the voltage out of permissible range. It may be the cause of
equipment damage.

down within 1 second.

GND (ground) terminal
In case of frequent noise generation on the power source line, it is
effective to earth the ground terminal directly to the ground. If the
instrument is not affected by environmental noise, the grounding can be
omitted. In this case, take care for the ground terminal not to touch
other input terminals, as it is charged with neutral electric potential of
power source voltage.
