If you use alcohol with lens tissue, avoid alcohol contamination by
observing these precautions:
• Use only unopened containers of alcohol. Alcohol absorbs water when
exposed to air, resulting in water spots when the alcohol evaporates.
• Transfer the alcohol to a squeeze bottle that can be capped and made
airtight.
• Never transfer alcohol back into the original container.
Maintaining the air sensor
By keeping the air sensor in good working condition, you can help ensure
measurement accuracy and speed.
Cleaning
Clean the sensor casing and cable using a cleaning solution, such as
Simple Green, applied to a soft cloth or paper wipe. Be careful not to spray
cleaner into the sensor case openings. Do not open the casing to clean
inside.
Checking accuracy quickly
Check the air sensor’s temperature reading by placing the sensor next to
an Agilent E1737A material temperature sensor. The material
temperature sensor must be facing up. After stabilization (allow 5 to
10 minutes), the two readings should be within 0.5 °C (0.9 °F).
Check the air sensor’s pressure reading against a calibrated barometer
placed in the same location. The two readings should be within 1.5 mm
(0.06 inch) Hg (200 Pa).
If the E1738A Air Sensor’s accuracy is outside these guidelines, return the
sensor to Agilent for calibration.
See “Returning sensors to Agilent for calibration” later in this chapter for
a list of authorized calibration facilities.
