PAINT RESISTANCE
MEASUREMENT KIT
Paint Resistivity
The Ransburg
Paint Resistance Measurement
Kit
using the multi-function meter is designed to
provide measurement of the electrical resistance of
paint formulations for all electrostatic applications.
Once the resistance of a paint is determined and
found to spray successfully, measuring resistiv-
ity with this meter provides a way to duplicate
conditions. This is extremely important when
troubleshooting problems with spray or rotational
applicators. This meter has two (2) scales, M
W
and k
W
that may be used for measurement of the
paint resistance.
Testing Metallic Paint
In certain paint
formulations where materials of appreciable
content of metal flake or powder (i.e., alumi-
num, bronze, or metallic colors) are used, this
method of testing resistance can be mislead-
ing or inconclusive. This paint tester will
NOT
indicate the metallic content of the formula.
Whenusing the paint tester with metal-
lic paints, the low voltage battery of the test
probe may not be enough to influence the
metal particles, therefore, their presence may
go unrecog-nized by the meter. When such
formulations are placed in electrostatic ap-
plicators and high voltage applied, the metal
particles may become aligned by the electri-
cal field. This may result in an appreciable
increase of current flow to ground by way of
the pain delivery system. While the flow of
current poses no immediate dangerous con-
dition, it may drain some or all of the voltage
from the electrode and may reduce or elimi-
nate electrostatic efficiency.
Ensure that meter's scale is properly set
for the function in which it is being used. Dam-
age to equipment may result if improperly set.

Operation
1. Set the meter dial to the M
W
scale (see Figure
6). Plug the paint probe into the side of the
meter.
2. Immerse the probe vertically into a well-mixed
representative sample of the subject paint until
the holes at the bottom of the slots in the probe
sleeve are submerged (see Figure 6). Take a
reading within 5 to 10 seconds of submerging
the probe.
Do not immerse the paint probe past the
top of the sleeve.
