materials and cause a re or
explosion.
Parts being sprayed and operators in the spray
area must be properly grounded.
Parts being sprayed must be supported on con-
veyors or hangers that are properly ground-
ed. The resistance between the part and earth
ground must not exceed 1 meg ohm. (Refer to
NFPA-33.)
Operators must be grounded. Rubber soled in-
sulating shoes should not be worn. Grounding
straps on wrists or legs may be used to assure
adequate ground contact.
Operators must not be wearing or carrying any
ungrounded metal objects.
When using an electrostatic handgun, operators
must assure contact with the handle of the ap-
plicator via conductive gloves or gloves with the
palm section cut out.

only as instructed.
Production should never be done with the safety
circuits disabled.
Before turning the high voltage on, make sure no
objects are within the sparking distance.
Explosion Hazard –
Incompatible Materials
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1,-Trichlo-
roethane are not chemically
compatible with the aluminum
that might be used in many sys-
tem components. The chemical
reaction caused by these sol-
vents reacting with aluminum
can become violent and lead to
an equipment explosion.
Aluminum is widely used in other spray appli-
cation equipment - such as material pumps,
regulators, triggering valves, etc. Halogenated
hydrocarbon solvents must never be used with
aluminum equipment during spraying, ushing,
or cleaning. Read the label or data sheet for the
material you intend to spray. If in doubt as to
whether or not a coating or cleaning material is
compatible, contact your coating supplier. Any
other type of solvent may be used with aluminum
equipment.

SPRAYABILITY, SCI,
AND RESISTANCE
MEASUREMENT KIT
Sprayability
The Sprayability Meter measures whether
materials 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 MW or GW. The target being sprayed
must be low enough in resistance 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 surface resistance reading to be
coated electrostatically 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 Ransburg Multi-Function
Electrostatic Spray Meter is useful to monitor and
maintain consistency in that application, once a
suitable reading is determined.
Operation
1. Set the meter dial to the MWor GWscale
(see Figure 2). Check the meter calibration by
touching the metallic end of the two (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 veried by
using a Volt-Ohm meter). If the meter reads
zero, the meter is in calibration. If it does not

erly set.
read zero, verify the continuity of the wire and
re-perform 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 rmly 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-Function Meter.
Meter Readings
0Wto 1.0GW - The article is suitable for spraying
using the electrostatic process.
1.0GW to 1.5GW- The article is questionable for
spraying using the electrostatic process. In such
cases, paint a trial sample article to determine if
a conductive primer or conductive solution for the
part surface is required.
1.5GW to Innity - The article is NOT suitable
for spraying. A conductive primer or conductive
solution is required to treat the surface of the part.

Resistance/Testing
Target/Product Ground
The Ransburg Multi-Function Meter may be used
to measure approximate resistance in kW, MW,
or GW. Applications for the meter range from
measuring the resistance of a 70430-XX resistor
to measuring the resistance of a target to ground.
Figure 3: Calibration Check Resistance
Operation
1. Set the meter dial to the MWscale (see Fig-
ure 3). Plug the probe with two (2) alligator
clamp leads into the side of the meter. Check
the meter calibration by touching the metallic
ends of the two (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 factory 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 MWscale. Read the resistance. If the
resistance is greater than 1.0 MWthe part is
not adequately grounded (reference NFPA-77,
NFPA-33).
3. For resistance checks, set the meter to MW
scale (see Figure 4). Attach one alligator clip
to the electrode wire of a 70430-XX screwed
onto a needle shaft (or similar component).
Attach the other lead to the shaft of the needle
shaft (or other end of a similar component).
The electrode reading should be approximately
14.5 MWto 19MW.

Short Circuit Current-SCI
(Power Supplies)
The Ransburg Multi-Function Meter may be used to
measure the short circuit current of an electrostatic
product. The short circuit current measurement is
important in troubleshooting problems with electro-
static power supplies and applicators. These tests
should be performed when a noticeable decrease
in transfer efciency occurs. The measured short
circuit current value should be compared to the
value listed in the appropriate power supply or
applicator manual. This comparison indicates if
there are problems with the power source or the
applicator.
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 µA scale (see Figure
5). Plug the probe with two (2) alligator clamp
leads into the side of the meter. Ensure the
meter reads zero. If it does not read zero,
consult the factory for repair of the meter.
2. Place appropriate test resistor in the high
voltage cable socket of the power supply.
See appropriate power supply or applicator
service manual. Be sure it is pushed clear
to the bottom or proper contact will not be
made. Attach one of the alligator clamps to
the lead of the test resistor. Attach the other
alligator clamp to a known true earth ground.
Turn the power supply on. Then trigger H.V.
by the air ow switch or jumper as required
by gun model. (See appropriate service man-
ual for further information.) Be sure that the
power supply lights indicate that high voltage
is being generated. Measure and record the
short circuit current from the meter. This value
should be compared to the value listed in the
appropriate power supply service manual.

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, MW
and kW that may be used for measurement of the
paint resistance.
Testing Metallic Paint In certain paint
formulations where materials of appreciable
content of metal ake 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 inuence 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 eld. This may result in an appreciable
increase of current ow to ground by way of
the pain delivery system. While the ow 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 efciency.
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.

Meter Readings
Table 4 lists the ranges of paint resistivity that work
best for specic Ransburg applicators.
To obtain MW- CM from the resistance in MW
from the meter, multiply by 132.
NEVER soak the paint probe. There
is no solvent seal at the point where the
handle screws into the body of the probe.
If solvent is allowed to enter at this point
or where the cable enters at the top of the
handle, the interior wiring will deteriorate
and have to be replaced.
MW- CM = MWreading X 132
(Ref. ASTM D5682)
Maintenance
The test probe MUST be cleaned IMMEDIATELY
after each use. Use a suitable solvent and clean
cloth to thoroughly clean the probe assembly.
1. Remove the probe sleeve and clean it inside
and out, removing all paint residues (it may
be soaked while probe is cleaned).
2. Thoroughly clean the outside of the probe with
the cloth and solvent.
3. Place the cleaned sleeve back on the probe.

* Use this table as a guideline. Usually a trial for resistance
above listed values is recommended. When resistance
is below listed values, electrostatic effect will be reduced
due to a higher current draw to ground. To spray this
material may require other means of increasing distance

HIGH VOLTAGE
MEASUREMENT KIT
High Voltage Measurement
The Ransburg High Voltage Measurement Kit
using the multi-function meter is designed to pro-
vide measurement of high voltage DC potential for
all electrostatic applicators to 200kV. Having an
accurate measurement of output voltage from an
applicator is very important when trouble-shooting
problems with an installation. The reading from this
device indicates whether the applicator and power
supply are operating correctly. This kit comes with
the following accessories:
1. A high voltage probe assembly to measure
DC voltage at a bell, disk or gun.
2. Five (5) feet of 3/8 inch diameter high voltage
cable to measure DC voltage from power
supplies of 90kV and higher.
3. Five (5) feet of 5/16 inch diameter high volt-
age cable to measure DC voltage from power
supplies producing less than 90kV.
Ensure that meter's scale is properly
set for the function in which it is being
used. Damage to equipment may result if
improperly set.
Operation
DO NOT exceed 30 seconds of continu-
ous use of the high voltage probe. The probe
is designed for instant readings

The ground clip MUST be connected to
a proven true earth ground BEFORE any
contact is made between the probe assembly
and the asembly being tested. All personnel
in the hazard (booth) area MUST be
grounded. See Ransburg bulletin "Personnel
Grounding".

2. Attach ground clamp to a proven earth ground.
For Guns
3. If measuring the voltage on an electrostatic
gun, line up the hole in the test probe and the
electrode. Slide the test probe straight over the
electrode wire of the gun. Be sure to push the
test probe tight against the nozzle to minimize
any voltage that may leak into the air during
the test.

To provide proper equipment to operator
ground, the conductive handle of the probe
MUST be held in the bare hand of the op-
erator. To avoid a shock hazard, the meter
should NEVER be disconnected fromthe
probe during high voltage contact.
These operating instructions MUST be read and
thoroughly understood by all personnel who use
this equipment. Special care should be taken to
ensure that all Warnings and Requirements for
operating the equipment safely are followed.
The user should be aware of and adhere to all
relevant local and company safety and re codes
and ordinances and the Occupational Heath Act
of 1970 (OSHA) prior to operating this equipment.
1.
Set the meter dial to the kV scale (see Figure 7).
Plug the high voltage probe into the side of
the meter.

Electrostatic AIr Spray Gun
4. Holding the metal part of the high voltage probe
in your hand, trigger the gun so voltage exists
at the electrode.
5. Read the voltage displayed on the meter in 30
seconds or less.
6. Turn the voltage to the gun OFF, and pull the
test probe straight off the electrode.
For Bells or Disks
7. Turn the high voltage power supply on.
8. Make and maintain sure contact between the
test probe and the applicator (see Figure 8).
Make sure all grounded objects are
at least 2 feet away.
NOTE
Ensure that the applicator is NOT rotating
when contacting it with the probe. Also, to
get proper readings on resistive applicators,
the probe must be placed in contact with the
atomizing edge of the bell or disk as shown
in Figure 8. As this edge is sensitive to me-
chanical damage, use care when contacting
it with the probe. Rough handling may cause
damage to the applicator.

Maintenance - Probe
1. Keep the test probe and the HV cables clean
to prevent contamination of the probe sockets.
Clean only with non-polar solvents.
2. Inspect the ground cable, its clamp and con-
nections for breaks or poor connections.
3. Do not bend or stress the white kV probe
assembly, as this may break the potted high
voltage resistor.

Calibration
The 76634-00 Multi-Function Meter is not eld
repairable. The meter should be returned to the
factory for repair or recalibration.
Ransburg recommends that the Multi-Function
Meter and its associated equipment (Paint probe,
kV Probe, and/or Test Leads) be sent in together
for recalibration at least once per year.
The best recalibration results the
Multi-Function Meter and accesories
(Paint probe, kV Probe, and/or Test
Leads) should be sent in together for
recalibration.
When shipped from the factory, and
after each calibration, the Multi-Function
Meter will be sealed with a calibration
sticker noting the next date when
calibration expires. Removal of this
seal will void calibration of the unit.
A certicate of calibration will also be
shipped with each calibrated unit.
