FUNCTIONAL DESCRIPTION

The PROTECTIVE GROUNDING SET TESTER uses a 5 volt direct current (dc) source to mea­sure resistances in grounding sets. Output current through the grounding set is limited to a
maximum of 10 amps by an internal current limiting resistor. The tester switches the 5 volt
power supply on, makes a measurement, and switches the power o again for a minimum of
500 milliseconds.

The tester uses a 4 wire resistance measurement approach to obtain accurate resistance mea­surements. The measurement system is auto ranging to give +/-1% accurate resistance mea­sure from 1 µΩ* to 6.5 Ω.

FEATURE DESCRIPTION

The following list of features are referenced with number 1 - 19, and the location of the feature
is shown on Figure 1.

1. Test Probes
Probes are used in troubleshooting mode to locate high resistance area of the ground

set.

3. Fixed Input Connections
When the ‘INPUT SELECT’ switch is in the fixed position. The resistance measurement

shown will be the value of resistance from one fixed connection through the ground set
to the other fixed connection.

4. Power Entry Module
Main power switch illuminates when power to the tester is on, and includes the fuse

holder compartment.

5. Preset Resistance Threshold
This number, shown on the display, is the pass/fail resistance threshold. The ‘<’ symbol

displayed means less than. For example, when ‘<3.333’ (mΩ**) is displayed, it means
that a ground set resistance which is less than 3.333 mΩ**.

6. Measured Ground Set Resistance
When the ‘INPUT SELECT SWITCH’ is in the ‘FIXED’ position. The value shown will be

the resistance measured from one fixed connection (3) through the ground set to the
other fixed connection (3). When the ‘INPUT SELECT SWITCH’ is in the ‘PROBE’ po­sition. The value shown will be the resistance measured between the probe contact
points.

7. Selected Cable Size
Indicates size of cable under test. This must be changed for each new size cable used.

*1 µΩ (1 micro ohm) = 0.000001 ohm
** mΩ (milli ohm) = 0.001ohm

Page 3

P403-3222 Rev. M 8/20

8. Continuous Test Switch
When switched to the ‘ON’ position, the ground set tester will continuously make

measurements at the rate of 1 per second. When switched to the ‘OFF’ position, the
ground set tester will hold the last measurement made.

9. Fail LED (Red)

SELF TEST PROCEDURE

The operation of the Protective Ground Set Tester can be verified using the Self Test Cable
included with the tester. It is not designed to test accuracy.

1. Place the tester on a table of convenient height and plug it into an AC outlet, 110 (Cat.
No. C403-3220) or 220 (Cat. No. PSC403-3220003) VAC.

2. Thread the attachment studs into fixed connection inputs.

3. Securely connect Self Test Cable to the attachment studs.

4. Turn on the unit. The power switch will illuminate when the power is on.

5. Place the ‘INPUT SELECT’ switch in the ‘FIXED’ position.

6. Place the ‘CONTINUOUS TEST’ switch in the ‘OFF’ position.

7. Press the ‘SINGLE TEST’ switch.

8. The display will show the measured resistance of the self test cable on line 2 of the
display. The resistance measured should be between 3.0 and 7.5 mΩ**. If the measured
resistance is outside these values, retighten the ball studs and check to make sure
that the self test cable has good electrical connections. After retest, if the measured
resistance is still not between 3.0 and 7.5 mΩ**, discontinue use of the tester. The Self
Test Cable is not designed with tight tolerances for accuracy testing.

Note that the thresholds and pass/fail LEDs will function during the self test but do not
pertain to the self test.

**mΩ (milliohm) = 0.001 ohm

TEST SETUP

Figure 3 shows the test setup required to test a protective ground set. The protective
ground set under test must always be connected between the fixed connection connections
regardless of the mode of testing. The ground set carries the test current from one fixed input
to the other during testing. Without the ground set, the resulting open circuit prevents the
resistance measurement. If the ground set is left unconnected and the ‘INPUT SELECT’ is in
the ‘FIXED’ position, the display will read ‘OVER RANGE’ after a test. If the ground set is left
unconnected and the ‘INPUT SELECT’ is in the ‘PROBE’ position, the display will be erratic.
The erratic display is unpredictable and does not indicate resistance.

Figure 3: Ground Set Testing Setup

Note: When measuring the ground set, cable length is expressed in feet (ferrule to ferrule
measurement to the nearest inch, not including shrouded portion of some ferrules which
cover the cable insulation).

P403-3222 Rev. M 8/20

GROUND SET TEST PROCEDURE

Use the Self Test Procedure to verify operation of the Ground Set Tester before testing

Ground Sets.

1. Place the tester on a table of convenient height and plug it into a nominal 120/240V AC
outlet.

2. Thread the attachment studs into the fixed connection inputs.

3. Brush the ground clamps to remove any oxidation or contamination and then securely
connect the Grounding Set to be tested to the attachment studs. A low resistance
connection must be maintained while testing the ground set. (Figure 3 shows typical
test setup.)

4. Turn on the unit. The power switch will illuminate when the power is on.

5. Use the ‘CABLE SIZE’ switch to select the cable size being tested. The cable size is
displayed at the end of the first line of the display.

6. Place the ‘INPUT SELECT’ in the ‘FIXED’ position.

7. Place the ‘CONTINUOUS TEST’ switch in the ‘OFF’ position.

8. Press the ‘SINGLE TEST’ switch.

9. The display will show the measured resistance between fixed connections on line 2 of
the display in mΩ.** When used in fixed mode the resistance displayed includes the
contact resistance of the connection studs to the ground set. The value shown in line
2 of the display needs to be less than the maximum resistance value from the tables
from the latest ASTM F2249 to be considered a passing ground set. If the measured
resistance is higher than the allowable value from ASTM F2249, then probing can be
used to locate the areas of high resistance in the ground set.

**mΩ (milli ohm) = 0.001 ohm

WARNING

!

Chance protective ground set tester is not designed nor recommended for detecting cable flaws.
Problems with the cable, away from the ferrule exit area, are often intermittent in nature.

NOTICE

If the ground set fails, there are two possibilities.

1. The ground set has a problem. Use probes to identify the high resistance section. See
section GROUND SET TROUBLESHOOTING WITH PROBES.

2. Cable is improperly sized for the application (AWG or length).

P403-3222 Rev. M 8/20

GROUND SET TROUBLESHOOTING WITH PROBES

The following sections describe how to use the probes in troubleshooting a ground set. Using
the probes in this mode, the high resistance areas of the ground set can be identified.

1. Place the tester on a table of convenient height and plug it into a nominal 120/240V AC
outlet.

2. Thread the attachment studs into the fixed connection inputs.

3. Connect the Grounding Set to be tested to the attachment studs. A low resistance
connection must be maintained while testing the ground set. Figure 3 shows typical test
setup.

4. Turn on the unit. The power switch will illuminate when the power is on.

5. Use the ‘CABLE SIZE’ switch to select the cable size being tested. The cable size is
displayed at the end of the first line of the display.

6. Place the ‘INPUT SELECT’ in the ‘PROBE’ position.

7. Place the ‘CONTINUOUS TEST’ switch in the ‘ON’ position. This causes the ground set
tester to repeatedly make measurements at a rate of about 1 per second.

8. In this mode the display will show the resistance across the part(s) of the ground set to
which the probes are connected. Start from one end of the ground set. Take resistance
readings between attachment stud and clamp body, clamp body to cable ferrule and
cable ferrule to cable ferrule. Repeat test on opposite end.

9. The display will show the measured resistance from one probe to the other when
contacting the ground set (on line 2 of the display in mΩ).

WARNING

!

Chance protective ground set tester is not designed nor recommended for detecting cable flaws.
Problems with the cable, away from the ferrule exit area, are often intermittent in nature.

EXPECTED GROUND SET RESISTANCE
The resistance through a Ground Set will be equal to the resistance of the cable itself and the
resistance of the cable clamps and connections to the cable. The resistance of the cable is
found by multiplying the resistance per foot for Class K copper cable by the number of feet
of the cable. Table 2 supplies the resistance per foot for various Class K cable sizes. The cable
clamps and connections should be less than 0.16 mΩ*. Since there are 2 clamps 0.32 mΩ* must
be added for the clamps and connections. Pass/Fail DC resistance values for Class K, M, H and
I copper grounding jumper assemblies can also be found in Tables X1.3, X2.3, X3.3 and X4.3 of
ASTM F2249-18.

For example, the expected resistance for a 32 foot 1/0 Ground Set will be less than

1.05 x 32 ft x 0.1030 mΩ/ft + 0.32 mΩ = 3.7808 mΩ**
