Chapter 7. Maintenance and Troubleshooting
The Model 8710 Micromanometer is designed for long-term field use. If used with reasonable care, it
should be able to make precise measurements over a long time period. Some of the components can be
cleaned periodically. When cleaning the components, please follow the instructions given below.
Fabric Hood
The hoods can be washed with mild detergent and cold water. When washing the hood, keep the hood
away from objects with sharp corners or sharp edges. Careless cleaning may cause damage.
If the fabric gets ripped it should be replaced or repaired. Duct tape can be placed over the rip on both
sides of the fabric for temporary repair.
If you wish to order a new hood fabric, use the following part numbers shown in
