Cleaning the sensor
Use Isopropyl (Isopropanol) alcohol only. Do NOT use Denatured alcohol as it leaves
residue after evaporation. Do not use other solvents as they may be too corrosive
and permanently damage the sensor and or its surroundings. Isopropyl of 90% pure
or better should be used. Hardware stores will sell 99% pure, found near the paint
thinners & solvents.

If your micron gauge is acting erratic, for instance, vacuum readings at atmosphere, readings rising
and falling during a steady pull down or holding vacuum, cleaning the sensor may be necessary.
After following steps 1-6 if you’re still experiencing issues, an alternate method to clean
the sensor is to soak the sensor in alcohol overnight.
