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
Desco Europe
Customer Service
.
Battery Replacement
Replace the batteries once the battery life indicator
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
Europe recommends cleaning this area once a month.
Cable jackets should also be cleaned in this fashion.
Cleaning the 2.27 kg Electrodes
Clean the electrodes with a minimum 70 % isopropanol-water
solution. Make sure the 2.27 kg electrodes’ conductive pads
are dry prior to use.

Measure Resistance Point-to-Point (Rtt) on the
Surface
1. Do not clean the surface.
2. Remove from the surface only those items that
might interfere with the test. ESD sensitive devices
shall also be removed.
3. Connect both test leads to both 2.27 kg electrodes,
and place the electrodes on the most commonly
used area of the surface. Use the 25 cm electrode
spacer to space them 25 cm apart from each other.
The electrodes should also be 5 cm away from any
edge and 8 cm away from any grounded point. If the
most used area is not obvious, use two points near
the center of the surface.
4. Push the red pushbutton to perform a measurement.
Should the 15-second electrification period appear,
it may be bypassed by pushing the red pushbutton
a second time.

5. Push the right black pushbutton to save the
measurement if desired.
6. Perform additional measurements by placing the
electrode on the most commonly used or worn area.
