Lens/source heater does not heat.

Table 15. Possible Remedies when Lens/source Heater does not Heat
Make sure the TSQ 9610 system and computer are properly connected.
Check the vacuum status as the heaters will not turn on until vacuum status reads OK.
Run Power Supply Check diagnostics to make sure the +24 V supply is working. If necessary, replace the power supply. See
Power Supplies for details.
Check the resistance on the 20-pin feedthrough.
Remove the analyzer tray and measure the electrical resistance of the lens heater and the source heater. See
Heater Block, and Lens/Source Heater
of the temperature sensors, which should be resistant at 50-300 ohms.

Lens/source heater overheats.

Table 16. Possible Remedies when Lens/source Heater Overheats
Make sure the wire insulation is not frayed, the wire is connected to the source interface board, and the wire is not in contact with any
metal surface along its length.
Remove the analyzer tray and measure the electrical resistance of the lens heater and the source heater. The resistance should be
approximately 24 ohms. You could also measure the resistance of the temperature sensors, which should be resistant at 50-300 ohms.
Make sure the leads to the heaters and sensors are not electrically shorted to the tray.

Transfer line does not heat.

Table 17. Possible Remedies when Transfer Line does not Heat
Check the vacuum status.
Remove the right side panel and disconnect the 4-pin connector to the transfer line. Then make sure the resistance of the heater circuit is
approximately 6 ohms and the resistance of the heater sensor is 50 to 300 ohms. If necessary, replace the transfer line.

Transfer line overheats.

Make sure the wire insulation is not frayed, the wire is connected to the source interface board, and the wire is not in contact with any
metal surface along its length.
Remove the right side panel and disconnect the 4-pin connector to the transfer line. Then make sure the resistance of the heater circuit is
approximately 6 ohms and the resistance of the heater sensor is 50 to 300 ohms. If necessary, replace the transfer line. See
