If the analyzer will not power up
q Check that the power cord is connected to the Agilent 89410A and to a live
power source.
q Check that the front-panel switch is on ( l ).
q Check that the voltage selector switch is set properly.
See ‘’To change the line-voltage selector switch’’ on page 1-8.
q Check that the fuse is good.
See ‘’To change the fuse’’ on page 1-9.
q Check that the analyzer’s air circulation is not blocked.
Cooling air enters the analyzer through the rear panel and exhausts through
both sides. If the analyzer’s air circulation is blocked, the analyzer powers
down to prevent damage from excessive temperatures. The analyzer
remains off until it cools down and its power switch is set to off (
O )then
to on (
l ).
q Obtain service, if necessary. See ‘’Need Assistance?’’ at the end of this guide.
