No operator serviceable parts inside. Refer servicing to qualified personnel.
To prevent electrical shock do not remove covers.
Fan is not Operating
Suspect a power supply problem or failed fan, and perform the following troubleshooting.
The opening of covers or removal of parts is likely to expose the user to
dangerous voltages. Disconnect the instrument from all voltage sources
before being opened.
1. Verify the front panel power switch (3101-4058) is operational.
2. Verify that the AC line voltage is correct (100 to 240 V at 50/60 Hz) and that the power cord is
not damaged. If the power cord is damaged, replace it. If the AC line voltage is incorrect, use
another receptacle.
3. Verify that the fuse (2110-0709) in line module is not blown. There is a spare fuse in the line
. If the fuse is working, continue to step 4.
4. Remove the top cover. Verify that the supply LED indicators, on the test set control board
(N5261-60006) are illuminated (Figure 61 below). The +9 and +10 V supplies will not be on. If
the LEDs are illuminated, replace the fan (87050-60027). Refer to
