Table 5-1. Common Operational Problems
What Happened Why What To Do
Nothing happens when
the power switch is
turned on (i.e., power
indicator does not
illuminate or there is
nothing on the display). Power cord is not fully
inserted at one end or the
other. Insert the power plug firmly into the
outlet socket; insert unit connector
firmly into power connector opening.
No power at the outlet. Plug in a lamp or small appliance to test
the outlet. If there is no power, contact
electrician.
Plug prongs are bent so
that contact is not made
at the outlet. Wiggle power plug at the outlet while
watching the display. If the display
comes on, have an electrician adjust the
prongs or replace the outlet or plug.
Power cord damaged. Have an electrician check the cord using
a test meter. Replace if defective.
Loose internal
connection, broken wire,
or failure of external
power supply. Contact a Micromeritics Service
Representative for repair or replacement
information.
