Maintenance
The Digital Surface Resistance Meter requires little
maintenance. There are no user serviceable parts. If the
meter requires service beyond cleaning the electrodes
or replacing the batteries, please contact the
.
Battery Replacement
Replace the batteries once the battery life indictator
is empty. Open the compartment located on the back
of the meter to replace the batteries. The meter uses
four AA alkaline batteries. Ensure that the batteries’
polarities are oriented in the correct fashion to avoid any
possible circuit damage.
Cleaning the Digital Surface Resistance Meter
The area surrounding the test jacks at the top end of the
meter should be wiped with a clean, isopropanol-alcohol
moistened cloth to remove skin oils that will accumulate
and affect the meter’s accuracy at high resistances.
The frequency of cleaning will depend on usage. Desco
recommends cleaning this area once a month. Cable
jackets should also be cleaned in this fashion.
Cleaning the 5 lbs. Electrodes
Per ANSI/ESD S4.1 “Clean the electrodes with a
minimum 70% isopropanol-water solution. Make sure
the 5 pound electrodes’ conductive pads are dry prior to
use.”
See specific product test standards for test lab
specimen cleaning instructions. Per ANSI/ESD S4.1
Worksurfaces “The test specimens and electrodes
shall be cleaned twice with a minimum 70%
isopropanol-water solution using a clean, low-linting
cloth each time.” (Note: The item should then be
conditioned for 72 hours minimum)
