DIGITAL VACUUM GAUGES DV-40S CLEANING AND REPAIR INSTRUCTIONS SH-35N DV-41 DV-22N CLEANING THE SENSOR If your vacuum gauge is behaving erratically, cleaning the sensor may be necessary. 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 and solvents. Follow steps 1-6 below. If issues continue, an alternate method of cleaning the sensor is to soak the sensor in alcohol overnight. If you have trouble getting an accurate reading after cleaning the sensor, please check your gasket or o-ring for damage, wear, or to see if it is missing. Tools Required Rubbing Alcohol (Isopropyl) Step 1 Liberally pour rubbing alcohol into the sensor. Step 2 Cover fitting opening with your thumb or finger. Step 3 Agitate the rubbing alcohol in the sensor to clean by shaking for a few seconds. Step 4 Dump excess alcohol. Step 5 Repeat steps 1-4 at least twice.
