10. Maintenance
10.1 Checking Site Ground Integrity
The CS110 electric field meter needs to be electrically connected to Earth
ground for valid measurements. It is recommended that the integrity of this
Earth Ground connection be checked periodically by verifying that the
resistance of the stator to Earth Ground rod is <1
Ω.
10.2 Corrosion and Rust Inhibitors
In corrosive environments, metal friction points (set screws, bolts, etc.) and
electrical connections to earth ground can be protected with the use of a rust
inhibitor. Sanchem makes such an inhibitor and some information on their
products may be found at http://www.sanchem.com/ox.html. Following is an
excerpt from their web site:
“NO-OX-ID A-SPECIAL is a soft, wax based rust preventive and lubricant
that contains an active rust inhibitor and small amount of solvent for ease of
application. This corrosion resistant coating can be applied by spray or brush
application. NO-OX-ID A-SPECIAL controls corrosion by leaving a thick,
semi-transparent, non-drying barrier coating that retains its anti-rust properties
indefinitely.
NO-OX-ID A-SPECIAL is the electrical contact grease of choice in new
electrical installations and maintenance because of its excellent performance in
keeping metals free from corrosion. This rust preventative has been used for
over 50 years to prevent corrosion in electrical connectors from low micro-
