at power-on. Hold down the
Shift Button as you power the unit on with
the AC Power Switch . A complete self test will start after holding the
Shift Button for three seconds. If the self test is successful, “PASS”
is displayed. If the self test is not successful, “FAIL” is displayed. If
“FAIL” is displayed, see Step F for information on returning the unit to
Wavelength for repair.
Verify that there is AC power to the temperature controller. First, check that
the
AC Power Switch is in the ON position. Also, make sure the power cord
is fi rmly plugged into the Power Entry Module on the rear panel. Check
that the fuse in the rear panel fuse holder is in place and functional. You
should also make sure that the power source you plugged the temperature
controller into is energized.
