2. PRODUCT FEATURES
2.1 Description
The Clamp-on Ground Resistance Tester Model 6416 measures grounding
electrodes and grid resistance without the use of auxiliary rods. Clamp-on ground
resistance testers can be used in multi-grounded systems without disconnecting
the ground system under test. The Model 6416 simply clamps around the
ground conductor or rod and measures the resistance to ground. By performing
measurements on intact ground systems, the user also veries the quality of the
grounding connections and bonds. Resistance and continuity of grounding loops
around pads and buildings can also be measured.
The Model 6416 includes a current measurement function. The ground tester’s
high sensitivity enables measurement of leakage current owing to ground or
circulating in ground loops from 0.2mA to 40A and resistances from 0.01 to
1500W.
Battery life information is displayed at power-up and the Auto Power OFF feature
can be enabled for power management. Additional features include the large
OLED (Organic Light Emitting Diode) display that ensures high readability of
data. The Buzzer and Auto Power OFF features can be disabled at any time.
The Model 6416 is equipped with an alarm function and data storage function. In
the Alarm mode, the probe will audibly and visually indicate when the reading is
beyond an input set point. You can also have the alarm activate above or below
the set point. This alarm feature permits quick eld checks where only “pass” or
“fail” readings are required.
The data storage function logs up to 300 measurements (W and/or A). This
enables you to conduct eld surveys, and to retrieve and analyze the readings
at a later time. The alarm settings and stored data are saved when the ground
tester is turned OFF.
Two new features unique to AEMC® are test frequency selection and touch
voltage indication.
The ability to select the test frequency provides more accurate measurements in
inductive environments.
Displaying voltage derived from current and resistance measurements provides
an extra level of safety for the user, indicating a potentially dangerous touch
condition.

2.2 Features
■ Simple and fast clamp-on operation - no leads, no auxiliary rods or spacing
requirements
- Ammeter: Current measurements from 0.2mA to 40A.
- Loop ohmmeter: Measurement of loop impedances from 0.01 to 1500W.
The ohmmeter function makes allowance for the presence of inductances
in the loop, making impedance measurements more accurate at low
values.
- Contact voltage: The contact voltage is determined by calculating the
product of the loop impedance and leakage current. The value found is an
upper bound on the voltage between the measurement point and earth,
since the impedance taken into account is that of the whole loop.
■ Touch voltage display
■ Large multi-function, bright yellow organic light emitting diode display (OLED)
■ Display in Standard mode (one screen) or Advanced mode (three screens)
■ Clamping diameter of 1.38" (35mm) accommodating cables up to 1000kcmil
■ Stores up to 300 measurements (W and/or A, with time-stamping)
■ Displays stored measurements on the display
■ Measurement hold by the HOLD and AUTO-HOLD functions
■ Clamp opening made easy by a trigger with a force compensation system
■ Auto Power OFF function
■ Alarm function with adjustable set point and buzzer for quick eld checks
■ Rugged Lexan® head and body construction resists breakage
■ Alarm settings and stored memory information saved during shutdown
■ NOISE icon and buzzer notify the user to presence of dangerous voltage and
current levels
■ Designed to EN 61010-1, 600V CAT IV safety standards
2.3 Applications
■ Ground electrode system resistance
■ Bonding/continuity checks
■ Cell tower grounding verication
■ Ground measurements on Railroad signaling systems

• AUTO-HOLD Function:
If the AUTO-HOLD mode was enabled during instrument SET-UP (see
§ 4.4, menu #11), opening the clamp acts as the identical state to the
HOLD mode for as long as the clamp is open. The benefit of this function
is that it makes it easy to freeze the measurement with one hand, when
access to the HOLD button is difficult.
If the HOLD button is not pressed during this time, closing the clamp

Σ
Ri

Σ
Ri
Typically, a grounded distribution system can be simulated by the basic circuit
shown in Figure 3-1 or an equivalent to the diagram shown in Figure 3-2. If
voltage (V) is applied to any measured grounding electrode Rx through a
special transformer; current (I) ows through the circuit, thereby establishing the
following equation:
V
= Rx +
I
Therefore, V/I = Rx is established. If I is detected and measured with V kept
constant, the measured grounding electrode resistance Rx can be obtained.
A signal is fed to a special transformer via a power amplier from a 2403Hz
constant voltage oscillator. The resulting current is then sensed by a detection
CT (current transformer). An active lter is used to dampen earth current at
commercial frequency (50/60Hz) and high-frequency noise.
Example: If clamped around any grounding electrode in a multi-grounded
system, the measured value of the electrode under test will be the resistance
of that particular rod in series with the equivalent parallel resistance value that
the rest of the multi-grounded system represents. If an electrical system had
101 grounding electrodes and each had a resistance value of 25W, and it were
clamped around any electrode in the system, the measured value would be 25W
in series with the equivalent parallel resistance of the other 100 electrodes or
0.25W. The displayed value would be 25.2W (instrument resolution to 0.1W).
n
i=1
where, usually

V/I = 25W + 0.25W
Rx = 25.2W
In most eld applications, the number of electrodes that make up a multi-
grounded system would be higher; therefore the equivalent parallel resistance is
negligible with respect to the rod under test.

the rst time the clamp is used or after it has been without battery power for more
than two minutes.
Set the function switch to Ω+A. All icons on the display light for approximately two
seconds. Enter the date and time using the ▲, ▼, and ► buttons.
The date and time can also be congured before a measurement in SET-UP (see
§ 4.4, menu #7 & #8).
NOTE: If time-stamping is not needed, this operation can be skipped by pressing
the ► button until the measurement screen corresponding to the switch setting
(Ω+A, A, MR or SET-UP) is displayed.

5.3 Display Example
Figure 5-2 shows a typical display upon
rst use, with the device set to Ω+A. In
this exampl, the measured current is
30.0mA and the impedance is 7.9W.
The buzzer is active and the memory is
empty.
NOTE: This display corresponds to the
device in Standard mode. In Advanced
mode, two additional screens are
available (see § 6.1.2.2).
Figure 5-3 shows a display, upon rst
use, with the device set to A. In this
example, the current measured is
30.0mA.
The buzzer is active and the memory is
empty.

Figure 5-3
5.4 Turning the Instrument ON
With the clamp closed and not clamped around any conductor, set the rotary
switch to a position other than OFF. All icons on the display light for approximately two seconds, before possible entry of the date and time (see § 5.2).
During the rst few seconds of operation, the clamp automatically adjusts
correction factors to optimize the impedance measurement. This correction
makes it possible to allow for the variations of the measurement head air gap that
may occur in some temperature and humidity conditions.
During this adjustment, the screen displays CAL GAP. If the clamp detects a
problem, it indicates Err CAL when the switch is set to Ω+A. Turn the instrument
OFF, disconnect it from any conductor and make sure the sensor heads are
clean with no obstructions, then turn it back ON.
When this adjustment is done, the clamp displays the screen corresponding to
the switch setting.
22 Clamp-on Ground Resistance Tester Model 6416
5.5 Turning the Instrument OFF
The instrument can be turned OFF in two ways:
■ Manually: Turn the rotary switch to OFF.
■ Auto Power OFF: This function activates after 5 minutes of no activity (no
button press, no change of switch setting, and no opening of the jaws).
- Fifteen seconds before Auto Power OFF, a short audible signal is emitted
and the display blinks once a second.
Auto Power OFF can be disabled in SET-UP (see § 4.4, menu #3). The
symbol is then displayed.
5.6 Standard and Advanced Modes
The instrument has two modes.
■ Standard Mode: Makes the standard loop resistance and leakage current
measurements.
■ Advanced Mode: Used to rene and complete the measurements:
- Impedance at the selected frequency.
- Contact voltage.
- Resistive and inductive components of the loop impedance.
The choice of Standard or Advanced mode and the alarm thresholds are
congured in SET-UP (see § 4.4, menu #9).
5.7 Memory
5.7.1 Memory Capacity
The Model 6416 can store up to 300 measurements. When its memory is full,
the sequence number is replaced by FULL. The next time the MEM button is
pressed, a beep is emitted and the FULL indication blinks. You will need to erase
the entire memory before recording again (see § 4.4, menu #1).
5.7.2 Storing Measurements into Memory
The values displayed during the measurements can be stored in memory and
read later.
Storage of the data is available in both the Ω+A and A measurement modes,
provided that memory locations are free.
Data is stored as soon as the MEM button is pressed. A long audible signal
conrms the storage.
Clamp-on Ground Resistance Tester Model 6416
23
All calculated impedance and/or current values, together with the values
accessible in the secondary screens in Advanced mode, are stored as soon as
the MEM button is pressed, such as:
■ Current measurement (A)
■ Measurement of the resistance, inductance, and impedance (Z)
■ Contact voltage measurement (V)
■ Present conguration of the clamp
■ Sequence number of the record
■ Time and date of the record
The display indicates the sequence number of the last measurement recorded,
or 0 if the memory is empty. The data is preserved when the device is OFF or
without a battery.
5.7.3 Reading Stored Data
The data can be read using the MR function (see § 6.3).
5.7.4 Erasing the Memory
Refer to § 4.4, menu #1.
5.7.5 Using the ▲ and ▼ Buttons
The ▲ and ▼ buttons are used to view the various stored measurements.
If these buttons are held down, the sequence number is scrolled at a rate
of 3 counts per second; after 5 seconds, the rate is increased to 10 counts
per second. Each time the sequence number changes, the value of the
corresponding measurement is displayed. The MR symbol remains displayed as
a reminder that the memory recall function is active.
It is possible to scroll past the oldest recorded value to the most recent, or past
the most recent recorded value to the oldest.
24 Clamp-on Ground Resistance Tester Model 6416
5.8 Alarm Management
The device has three distinct alarms that can be congured.
NOTE: The (W, V, A) alarm thresholds can be configured in SET-UP (see §4.4).
5.8.1 Voltage Alarm
■ If the voltage (product ZxI) exceeds
the threshold set, the alarm symbol
and the alarm threshold blink.
■ If the buzzer is active, a high-pitched
audible warning signal is emitted.
Figure 5-4
5.8.2 Current Alarm
■ If the current exceeds the threshold
set, the alarm symbol and the alarm
threshold blink.
■ If the buzzer is active, a low-pitched
audible signal is emitted.
Figure 5-5
5.8.3 Impedance Alarm
If there is no voltage alarm, no detection of noise, and no current alarm, an alarm
on the impedance may be triggered. If the buzzer is enabled, the corresponding
audible signal is emitted.
■ Low Threshold Conguration:
An audible signal is emitted when the
impedance is below the threshold set
(continuity type measurement).
■ High Threshold Conguration:
An audible signal is emitted at values
exceeding the threshold (detection
of a grounding impedance that is too
high).
If the impedance crosses the selected threshold, a low-pitched audible signal is
emitted.
Clamp-on Ground Resistance Tester Model 6416
Figure 5-6

5.8.4 No Alarm Detection
If no alarm is activated, the alarm icons are not displayed.
■ When no alarm is triggered, the
alarm threshold is displayed,
along with the direction
of triggering (
impedance, voltage, or current

, ) of the
Figure 5-7
5.8.5 Priority of the Alarms
If several alarms are triggered simultaneously, a priority rule determines the
display and the corresponding sound:
■ The voltage alarm has priority because it concerns the user’s safety.
■ The current alarm is second in priority.
■ The impedance alarm is displayed when no other alarm is triggered.
26 Clamp-on Ground Resistance Tester Model 6416
6. MEASUREMENT MODES
6.1 Rotary Position W+A
6.1.1 Standard Mode
Selection of Standard mode is performed in the SET-UP (see § 4.4, menu #9).
In Standard mode, only one measurement screen is available. The clamp
measures the loop impedance (W) (at the xed frequency of 2083Hz) and the
leakage current.
NOTE: Since the measurement frequency is audible, the operator hears a beeping
signal. This is neither an operating fault nor an alarm, and it cannot be eliminated.
This audible signal is amplified by the presence of current in the loop.
The alarm thresholds can be congured as desired (see § 4.4, menus #4, #5 &
#6).
6.1.1.1 Making a Measurement
■ Turn the rotary switch to the Ω+A position, and wait several seconds
while the instrument performs internal calibration.
■ Clamp around the conductor to be measured. If the clamp is incorrectly
closed, the icon is displayed.
■ If necessary, use the HOLD button to freeze the measurement.
■ If necessary, use the MEM button to store the measurement.
NOTE: If the measured impedance is less than 1W, the measurement display
alternates between the value measured and the word LOOP, in order to call the
user’s attention to the risk of measuring a local loop at the test point that does
not include the earth/ground measurement.
Clamp-on Ground Resistance Tester Model 6416
27
6.1.1.2 Measurement Results
Once the measurement has stabilized, the display
indicates:
- The leakage current.
- The impedance of the loop at the frequency of
2083Hz.
The impedance is measured only if the leakage
current is less than 10A. In the 10 to 40A range, only
the current is displayed; the NOISE symbol blinks
and the impedance is replaced by dashes.
To store the measurement into memory, press the MEM button (see § 5.7.2).
If the contact voltage exceeds 50V, the display indicates the current/impedance
measurements and the contact voltage alternately.
Figure 6-1
6.1.2 Advanced Mode
Selection of Advanced mode is performed in the SET-UP (see § 4.4, menu #9).
In this mode, three measurement screens are provided, impedance referred
to the chosen frequency and leakage current, contact voltage, display of R
(resistance) and L (inductance). The clamp measures the loop impedance
(W) at the frequency of 2083Hz. However, in addition to what is measured in
Standard mode, the impedance is recalculated at the frequency dened by the
conguration.
The frequency and alarm thresholds can be congured as desired (see § 4.4,
menus #4, #5 & #6).
6.1.2.1 Making a Measurement
■ Turn the rotary switch to the Ω+A position, and wait several seconds
while the instrument performs internal calibration.
■ Clamp around the conductor to be measured. If the clamp is incorrectly
closed, the icon is displayed.
■ If necessary, use the HOLD button to freeze the measurement.
■ If necessary, use the MEM button to store the measurement.
