Checking the Vacuum and Temperature
Use the lights on the front of the ISQ instrument to check the vacuum and temperature of the
instrument.
To check the vacuum, look at the Vacuum light. When the light is a solid green, the ISQ mass
spectrometer is under sufficient vacuum. If it is slowly blinking orange, you have not achieved
vacuum yet. If it is blinking orange quickly, you have a large leak that prevented the
instrument from achieving vacuum. If this is the case, you need to find and fix the leak, then
turn the power off and on. Most likely, the column nut needs to be tightened, the column was
not installed correctly, or the vent valve was not completely closed.
To check the temperature, look at the Heaters light. When the Heaters light is a solid green,
the ISQ instrument is at temperature. If it is blinking orange, the ion source or transfer line
are not at temperature. If the light is not lit, the heaters are not turned on.

Note Until the Vacuum light is a solid green (high vacuum is achieved), the heaters will
not power on and the Heaters light will not be lit.
