MULMULTI-FUNCTIONTI-FUNCTION
ELECTROSTELECTROSTAATIC METERTIC METER
The ITW Ransburg Multi-Function Electrostatic
Spray Meter uses one meter to serve multi
functions in electrostatic spray finishing. The
meter can be used to measure conductivity,
paint resistance, short circuit current, resis-
tance, and high voltage. The meter is available
in individual kits focused on each function or a
deluxe kit, which includes accessories to per-
form all the functions listed above.
The ITW Ransburg Multi-Function Electrostatic
Spray Meter is powered by a single 9V alkaline
battery. The solid state circuitry only requires
9V input to power the meter display and condi-
tion all the signals from the accessory items.

SprayabilitySprayability
The sprayability meter measures whether mate-
rials normally considered being electrically non-
conductive could be electrostatically sprayed or
whether they need to be treated with solutions
to make the surface conductive. The meter
measures the surface resistance and indicates
the degree of sprayability in MΩor GΩ. The
target being sprayed must be low enough in re-
sistance to dissipate the electrostatic charge.
In some cases the internal resistance of a target
is lower than the surface resistance. This might
allow a target that does not have a suitable sur-
face resistance reading to be coated electro-
statically without additional surface preparation.
An example of this is certain types of wood
which on the surface are not conductive but due
to moisture content (12%-13%) may be
sprayable.
Since many non-conductive products must be
pre-treated with a conductive solution to make
them sprayable, the ITW Ransburg Multi-Func-
tion Electrostatic Spray Meter is useful to moni-
tor and maintain consistency in that application,
once a suitable reading is determined.

OperationOperation
1. Set the meter dial to the MΩor GΩ
scale (see Figure 2). Check the meter calibra-
tion by touching the metallic end of the (2)
probes on the meter to the stripped bare ends of
a single 12" long wire (see Figure 2). (If desired
the continuity of the wire may be verified by us-
ing a Volt-Ohm meter). If the meter reads zero,
the meter is in calibration. If it does not read
zero, verify the continuity of the wire and re-per-
form the check. If the meter still does not read
zero, consult the factory for repair of the meter.
2. With the metallic part of the meter
probes pressed firmly and perpendicular against
the surface of the article to be tested, the meter
automatically reads the resistance of the part.
Table 1 lists the readings from an 8333-00
meter and compares it to the readings of the
Multi-FunctionMeter.

such cases, paint a trial sample article to deter-
mine if a conductive primer or conductive solu-
tion for the part surface is required.

The Ransburg Multi-Function Meter may be
used to measure approximate resistance in
kΩ, MΩor GΩ. Applications for the meter
range from measuring the resistance of a
70430-00 resistor to measuring the resistance
of a target to ground.
NOTENOTE
When using the Multi-Function Meter test leads
to measure resistance or current, ensure that
the sprayability probes do not come into contact
with any surface or the meter readings may be
altered.

OperationOperation
1. Set the meter dial to the MΩ scale (see
Figure 3). Plug the probe with (2) alligator
clamp leads into the side of the meter. Check
the meter calibration by touching the metallic
ends of the (2) probes together. If the meter
reads zero, the meter is in calibration. If it does
not read zero, verify the continuity of the probe
assembly and re-perform the check. If the
meter still does not read zero, consult the fac-
tory for repair of the meter.
2. For ground checks, attach one alligator
clip to a clean, non-treated surface of the target
to be sprayed. Attach the other alligator clip to
a known true earth ground. Set the dial to the
MΩscale. Read the resistance. If the resis-
tance is greater than 1.0 MΩthe part is not ad-
equately grounded (reference NFPA 77, NFPA
33).
3. For resistance checks, set the meter to
MΩscale (see Figure 4). Attach one alligator
clip to the electrode wire of a 70430-00 screwed
onto an 18865 needle shaft (or similar compo-
nent). Attach the other lead to the shaft of the
18865-needle shaft (or other end of a similar
component). The electrode reading should be
approximately 14.5 MΩto 19MΩ.
