JUST BETTER DV-22N Digital Vacuum Gauges Instruction Manual
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)
REPLACING THE GASKET
Check your vacuum gauge to determine if a gasket or o-ring is present. For gauges using a gasket, use replacement part P511 and follow steps below. For gauges using an o-ring, refer to REPLACING THE 0-RING instructions.
Tools Required
- Needle nose pliers
- P511 replacement gasket
REPLACING THE O-RING
Check your vacuum gauge to determine if a gasket or o-ring is present. For gauges using an o-ring, use replacement part P90009. For gauges using a gasket, refer to REPLACING THE GASKET instructions.
