3. USE
3.1. GENERAL
When it leaves the plant, the device is configured so that it can be used without changing the parameters. For most measurements, simply select the measurement function by turning the switch and press the TEST button.
However, you can also parameterize:
the measurements, using the function keys,
or the device itself, using SET-UP.
The device is not designed to operate when the charger is connected. The measurements must be made using battery
power.
3.1.1. CONFIGURATION
When configuring the measurements, you can always choose between:
validating by pressing the OK key,
or exiting without saving by pressing the key.
3.1.2. HELP
In addition to an intuitive interface, the instrument provides complete help in use and analyses and appraisals. Three types of
help function are available:
Help before the measurement can be accessed using the key. It indicates the connections to be made for each function
and important recommendations.
Error messages appear, as soon as the TEST button is pressed, to report connection errors, measurement parameterizing
errors, out-of-range values, defective installations tested, etc.
Help associated with the error messages. Messages containing the icon invite you to look up the help for ways to
eliminate the error found.
3.1.3. REFERENCE POTENTIAL
The user is assumed to be at the reference earth potential. He/she must therefore not be insulated from earth: must not
wear insulating shoes or insulating gloves and must not use a plastic object to press the TEST button.
3.2. VOLTAGE MEASUREMENT
Whichever function is chosen, except for SET-UP, the device always starts by measuring the voltage present on its terminals.
3.2.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device separates the alternating voltage from the direct voltage and compares the amplitudes to decide whether the signal
is AC or DC. In the case of an AC signal, the frequency is measured and the device calculates the RMS value of the AC part and
displays it. In the case of a DC signal, the device does not measure its frequency, but calculates its mean value and displays it.
For measurements made at the mains voltage, the device checks that the connection is correct and displays the position of the
phase on the socket outlet. It also checks the presence of a protective conductor on the PE terminal by means of the contact the
user makes with his/her finger by touching the TEST button.
11
3.2.2. MAKING A MEASUREMENT
Connect the lead to the device to be tested. As soon as the device is powered up, it measures the voltages present on its terminals
and displays them, whatever the setting of the switch.
/
In the ZS (RA/SEL.) and RCD, settings, the device also indicates the position of the phase on the display unit using the symbol.
The mains socket outlet of the measuring cable is marked with a white reference spot.
: the phase is on the right-hand contact of the mains plug when the white spot is up.
: the phase is on the left-hand contact of the mains plug when the white spot is up.
: the device cannot determine where the position of the phase, probably because the PE is not connected or the L and
PE conductors are interchanged.
The L symbol is displayed as soon as the voltage is high enough (> UL programmable in SET-UP). The terminal identified
as L is the one that has the highest voltage with respect to PE.
3.2.3. ERROR INDICATION
The only errors reported in voltage measurement are values outside the voltage measurement range. These errors are reported
in clear language on screen.
12
3.3. RESISTANCE AND CONTINUITY MEASUREMENT
3.3.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
For continuity measurements, the device generates a DC current of 200 or 12 mA, at the user’s discretion, between the W and
COM terminals. It then measures the voltage present between these two terminals and from it deduces the value of R = V/I.
For resistance measurements (current chosen = kW), the device generates a DC voltage between the W and COM terminals. It
then measures the current between these two terminals and from it deduces the value of R = V/I.
In the case of a measurement at high current (200 mA), at the end of one second, the device reverses the direction of the current
and makes another measurement for one second. The result displayed is the mean of these two measurements. It is possible to
make measurements with either the positive or the negative polarity of the current disabled.
For measurements at low current (12 mA or kW), the polarity is positive only.
3.3.2. MAKING A MEASUREMENT
To comply with standard IEC-61557, the measurements must be made at 200 mA. The reversal of the current serves to compensate for any residual electromotive forces and, more important, to check that the continuity is in fact duplex.
When you make continuity measurements that are not contractual, prefer a current of 12 mA. Even though the results cannot be
regarded as those of a normative test, this significantly increases the life of the device between charges and forestalls untimely
tripping of the installations if there is a connection error.
The permanent mode is used to chain measurements without having to press the TEST button each time.
If the object to be measured is inductive, it is better to switch to pulse mode at 200 mA and make a measurement at positive
polarity, then a measurement at negative polarity, manually, in order to leave time for the measurement to settle.
The alarm, if activated, serves to inform the user, by an audible signal, that the measurement is below threshold, making it unnecessary to look at the display unit to check this point.
Set the switch to W .
Use the leads to connect the device to be tested between the W and COM terminals of the device. The object to be tested must not be live.

3.3.3. CONFIGURING THE MEASUREMENT
Before starting the measurement, you can configure it by modifying the parameters displayed:
Choice of measurement current: kW, 12 mA or 200 mA.
200mA
The high current (200 mA) can be used only to measure low resistances, up to 40 W.
The low current (12 mA) is used to make measurements up to 400 W.
The choice kW is used to make resistance measurements up to 400 kW.
To correct for the resistance of the measurement leads (leads and probe tips or crocodile clips), for measurements
at 12 and 200 mA (see §3.16).
Pressing the TEST button starts only one measurement (pulse mode).
Pressing the TEST button starts the continuous measurement (permanent mode). To
stop it, you must press the TEST button again.

3.3.5. ERROR INDICATION
The commonest error in the case of a continuity or resistance measurement is the presence of a voltage on the terminals. An error
message is displayed if a voltage greater than 0.5 VRMS is detected and you press the TEST button.
In this case, the measurement is not enabled. Eliminate the cause of the interference voltage and start the measurement over.
Another possible error is measurement of an overly inductive load that prevents the measurement current from stabilizing. In this
case, start the measurement in permanent mode with only one polarity and wait for the measurement to stabilize.

3.4. INSULATION RESISTANCE MEASUREMENT
3.4.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device generates a DC test voltage between the COM and MW terminals. The value of this voltage depends on the resistance
to be measured: it is greater than or equal to UN when R ≥ RN = UN /1 mA, and less otherwise. The device measures the voltage
and current present between the two terminals and from them deduces the value of R = V / I.
The COM terminal is the voltage reference point. The MW terminal therefore provides a negative voltage.
3.4.2. MAKING A MEASUREMENT
The alarm, if activated, serves to inform the user, by an audible signal, that the measurement is below threshold, making it unnecessary to look at the display unit to check this point.
Set the switch to MW.
Use the leads to connect the device to be tested between the COM and MW
terminals of the device. The object to be tested must not be live.

3.5. 3P EARTH RESISTANCE MEASUREMENT
This function is the only one that can measure an earth resistance when the electrical installation to be tested is not live (new installation, for example). It uses two auxiliary rods, with the third rod being constituted by the earth electrode to be tested (whence
the name “3P”).
It can be used on an existing electrical installation, but the power must be cut off (main RCD). In all cases (new or existing installation), the earthing strip of the installation must be open during the measurement.
It is possible to make a rapid measurement and measure only RE or else to make a more detailed measurement by also measuring the resistances of the rods.
3.5.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device generates between the H and E terminals a square wave at a frequency of 128 Hz and an amplitude of 35 V. It measures the resulting current, IHE , along with the voltage present between the S and E terminals, USE. It then calculates the value of
RE = USE/IHE.
To measure the resistances of the RS and RH rods, the device internally reverses the E and S terminals and makes a measurement.
It then does likewise with the E and H terminals.
3.5.2. MAKING A MEASUREMENT
There are several measurement methods. We recommend the «62%» method.
Set the switch to RE 3P.
Plant the H and S rods in line with the earth electrode. The distance between the S rod
and the earth electrode must be approximately 62% of the distance between the H rod
and the earth electrode.
In order to avoid electromagnetic interference, we recommend paying out the full length of

The alarm, if activated, serves to inform the user, by an audible signal, that the measurement is above threshold, making it unnecessary to look at the display unit to check this point.
3.5.3. CONFIGURING THE MEASUREMENT
Before starting the measurement, you can configure it by modifying the parameters displayed:
Choice of type of measurement: rapid, to measure RE only (icon crossed out), or detailed, to measure also rod
resistances RS and RH. This last case is useful if the ground is dry, making the resistance of the rods high.
To compensate for the resistance of the lead connected to the E terminal, for measurements of low values (see §3.16).

The 3 measurement results must be the same to within a few percent. If this is the case, the measurement is valid. If not, it is
because the S rod is in the zone of influence of the earth electrode.
If the resistivity of the ground is homogeneous, it is necessary to increase distance d and repeat the measurements. If the resistivity of the ground is inhomogeneous, the measurement point must be moved either towards the H rod or towards the earth
terminal until the measurement is valid.
3.5.6. POSITIONING OF THE AUXILIARY RODS
To make sure that your earth measurements are not distorted by interference, we recommend repeating the measurement with
the auxiliary rods placed at a different distance and in another direction (for example rotated 90° from the first alignment).

If you find the same values, your measurement is reliable. If the measured values are substantially different, it is probable that
they were influenced by earth currents or a groundwater artery. It may be useful to drive the rods deeper.
If the in-line configuration is not possible, you can plant the rods in a triangle. To validate the measurement, move the S rod on
either side of the line HE.

Avoid routing the connecting cables of the earth rods near or parallel to other cables (transmission or power supply), metal pipes,
rails, or fences, this in order to avoid the risk of cross-talk with the measurement current.
22
3.5.7. ERROR INDICATION
The commonest errors in the case of an earth measurement are the presence of an interference voltage or rod resistances that
are too high.
If the device detects:
a rod resistance greater than 15 kW,
a voltage greater than 25 V on H or on S when the TEST button is pressed.
In these two cases, the earth measurement is not enabled. Move the rods and start the measurement over.
To reduce the resistance of the rods RH (RS), you can add one or more rods, two metres apart, in the H (S) branch of the circuit.
You can also drive them deeper and pack the earth around them, or wet it with a little water.

3.6. LOOP IMPEDANCE MEASUREMENT (ZS)
R
R
In a TN or TT type installation, the loop impedance measurement is used to calculate the short-circuit current and to size the
protections of the installation (fuses or RCDs), especially their breaking capacity.
In a TT type installation, the loop impedance measurement makes it easy to determine the earth resistance without planting any
rods and without cutting off power to the installation. The result obtained, ZS, is the loop impedance of the installation between
the L and PE conductors. It is barely greater than the earth resistance.
From this value and the conventional touch voltage limit (UL), it is then possible to choose the rated differential operating current
of the RCD: IDN < UL / ZS.
This measurement cannot be made in an IT type installation because of the high earthing impedance of the supply transformer,
which may even be completely isolated from earth.
3.6.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device starts by generating pulses having a duration of 1.1 ms and an amplitude of at most 7 A between the L and N terminals. This first measurement is used to determine ZL.
It then applies a low current, 6, 9 or 12 mA at the user’s discretion, between the L and PE terminals. This low current serves to
avoid tripping residual current devices of which the nominal current is greater than or equal to 30 mA. This second measurement
is used to determine ZPE.
The device then calculates loop resistance ZS = Z
= ZL+ZPE , and short-circuit current Ik = U
L-PE
LPE/ZS
.
The value of Ik serves to check the proper sizing of the protections of the installation (fuses or RCDs).
For greater accuracy, it is possible to measure ZS with a high current (TRIP mode), but this measurement may trip the RCD of
the installation.
3.6.2. MAKING A MEASUREMENT
Set the switch to ZS (RA/SEL.).
Connect the measuring cable to the device, then to the socket outlet of the installation to be tested.
SET UP
At the time of connection, the device first checks that the voltages present
on its terminals are correct, then determines the position of the phase (L) and
of the neutral (N) with respect to the protective conductor (PE) and displays
it. If necessary, it then automatically switches the L and N terminals so that
the loop measurement can be made without modifying the connections of
the device.
OFF
If possible, first disconnect all loads from the network on which you make the loop
measurement.
It is possible to eliminate this step if you use a measurement current of 6 mA, which
allows a leakage current of up to 9 mA for an installation protected by a 30 mA
residual current device.

3.6.3. CONFIGURING THE MEASUREMENT
Before starting the measurement, you can configure it by modifying the parameters displayed:

Choice of measurement current in non-tripping mode: 6, 9, 12 mA
or TRIP mode to use a high current that will give a more accurate measurement.
To compensate for the resistance of the measurement leads, for measurements of low values (see §3.16).

The device proposes choosing the voltage for the Ik calculation from among the following values:
(Ik)
ULN (the measured voltage value),
the voltage of the old standard (for example 220 V),
the voltage of the current standard (for example 230 V).
Depending on the voltage ULN measured, the device proposes the following choices:
if 170<ULN<270 V: ULN, 220 V, or 230 V.
if 90<ULN<150 V: ULN, 110 V or 127 V.

R
R
This function is used to make an earth resistance measurement in a place where it is impossible to make a 3P earth measurement
or to disconnect the earth connection strap, often the case in an urban environment.
This measurement is made without disconnecting the earth, with only one additional rod, saving time with respect to a conventional earth measurement with two auxiliary rods.
In the case of a TT type installation, this measurement is a very simple way to measure the earth of frame grounds.
In the case of a TN type installation, to determine the value of each of the earths put in parallel, it is necessary to perform a selective earth measurement on live circuit using a current clamp (see §3.8). Without this clamp, what you find is the value of the
global earth connected to the network, which is rather meaningless.
It is then more useful to measure the loop impedance to size the fuses and RCDs, and to measure the fault voltage to check the
protection of persons.
3.7.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device starts by making a loop measurement ZS (see §3.6) with a low current or a high current, at the user’s discretion. It
then measures the potential between the PE conductor and the auxiliary rod and from it deduces RA = U
chosen by the user.
For greater accuracy, it is possible to make the measurement with a high current (TRIP mode), but this measurement may trip
the RCD of the installation.

An earth rod resistance that is too high (>15 kW): reduce it by packing the earth around the rod and moistening it.
A voltage on the protective conductor that is too high.
A voltage on the rod that is too high: move the rod out of the influence of the earth electrode.
Tripping in the non-tripping mode: reduce the test current.
A current measured by the clamp in selective earth on live circuit that is too low: the measurement is not possible.
The user may have picked up a charge of static electricity, for example by walking on a carpet. In this case, when he/she
presses the TEST button, the device displays the error message «earth potential too high». The user must then be discharged by touching an earth before making the measurement.

3.10. MEASUREMENT OF THE VOLTAGE DROP IN THE CABLES (DV)
For the C.A. 6117 only. The voltage drop in the cables is measured to check that the cross section of the cables is sufficient for the
installation. A voltage drop that is too large (> 5%) means that the cross section of the cables is too small.
This measurement can be made whatever the type of neutral used in the installation.
3.10.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device makes a first measurement of Zi at a reference point, then a second measurement of Zi at the measurement point.
The voltage drop is then calculated: DV = 100 (Zi - Zi ref ) x IN / U
The result is expressed in %.
3.10.2. MAKING A MEASUREMENT
. IN is the rated current of the fuse that protects the installation.

You must make two measurements.
For the first, connect the tripod cable/3 safety leads to the instrument. Operate just
after the fuse that protects the installation. Connect the L cord (red) to the phase and
SET UP
the N cord (blue) to the neutral. Connect the PE cord (green) to the N cord (blue).
At the time of connection, the device first checks that the voltages present on
its terminals are correct, then determines the position of the phase (L) and of
the neutral (N) with respect to the protective conductor (PE) and displays it.
If necessary, it then automatically switches the L and N terminals so that the line

Before starting the measurement, you can configure it by modifying the parameters displayed:
To select the measurement of Zi (line measurement impedance) or of V (measurement of the voltage drop in the
cables). Here, you must select DV.
To compensate for the resistance of the measurement leads, for measurements of low values (see §3.16).

The delay (the duration of application of IN before the fuse blows): 0.1 s, 0.2 s, 0.4 s, 5 s and 35
minutes.
The device then deduces Isc from this and displays it.
The device proposes choosing the voltage for the Ik calculation from among the following values:
ULN (the measured voltage value),
the voltage of the old standard (for example 220 V),
the voltage of the current standard (for example 230 V).
Depending on the voltage ULN measured, the device proposes the following choices:
if 170<ULN<270 V: ULN, 220 V, or 230 V.
if 90<ULN<150 V: ULN, 110 V or 127 V.

3.11. TEST OF RESIDUAL CURRENT DEVICE
The device can be used to perform three types of test on RCDs:
a tripping test in ramp mode,
a tripping test in pulse mode,
a non-tripping test.
The test in ramp mode serves to determine the exact value of the tripping current of the RCD.
The test in pulse mode serves to determine the tripping time of the RCD.
The non-tripping test serves to check that the RCD does not trip at a current of 0.5 IDN. For the test to be valid, the leakage current
must be negligible with respect to 0.5 IDN and, to ensure this, all loads connected to the installation protected by the RCD that is
being tested must be disconnected.
3.11.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
For each of the three types of test, the device starts by checking that the RCD can be tested without compromising the user’s
safety, i.e. without causing the fault voltage, UF , to exceed 50 V (or 25 V or 65 V according to what is defined in the SET-UP for
UL ). The device therefore starts by generating a low current (<0.3 IDN) in order to measure ZS, as it would for a loop impedance
measurement.
It then calculates UF = ZS x IDN (or UF = ZS x 2 IDN or UF = ZS x 5 I
depending on the type of test requested), which will be the
DN
maximum voltage produced during the test. If this voltage is greater than UL, the device does not perform the test. The user can
then reduce the measurement current (to 0.2 IDN) so that the test current combined with the leakage current present in the installation will not lead to a voltage greater than UL.
For a more accurate measurement of the fault voltage, we recommend planting an auxiliary rod, as for earth measurements on
live circuits. The device then measures RA and calculates UF = RA x IDN (or UF = RA x 2 IDN or UF = ZS x 5 I
depending on the type
DN
of test requested).
Once this first part of the measurement has been made, the device goes on to the second part, which depends on the type of test.
For the ramp mode test, the device generates a sinusoidal current of which the amplitude increases gradually from 0.3 to 1.06
IDN between the L and PE terminals for type AC and A RCDs and from 0,2 to 2,2 IDN for type B RCDs. When the RCD opens
the circuit, the device displays the exact value of the tripping current and the tripping time. This time is an indication and may
differ from the trip time in pulse mode, which is closer to the operational reality.
For the pulse mode test, the device generates a sinusoidal current at the mains frequency, having an amplitude of IDN, 2 IDNor
5 IDN between the L and PE terminals for type AC and A RCDs and 2 IDN or 4 IDN for type B RCDs, lasting at most 500 ms. And
it measures the time the RCD takes to open the circuit. This time must be less than 500 ms.
For the non-tripping test, the device generates a current of 0.5 IDN for one or two seconds, depending on what the user has
programmed. Normally, the tripping must not trip.
In the ramp and pulse mode tests, if the RCD does not trip, the device sends a current pulse between the L and N terminals. If
the RCD trips, it is because it was incorrectly installed (N and PE reversed).
3.11.2. PERFORMING A TEST IN RAMP MODE
Set the switch to RCD .
SET UP
Connect the measuring cable to the device, then to a socket outlet included in the circuit
protected by the RCD to be tested.
At the time of connection, the device detects the positions of the phase (L) and
of neutral (N) with respect to the protective conductor (PE) and displays them. If
necessary, it then automatically switches the L and N terminals so that the test
can be done without modifying the connections of the terminals.

the test.
To make a more accurate measurement of the fault voltage, plant the auxiliary rod at a distance of more than 25 metres

The commonest errors in the case of a test of a residual current device are:
The RCD did not trip out during the test. Now, to ensure the safety of users, a RCD must trip within 300 ms, or 200 ms for a
type S. Check the wiring of the RCD. If it is OK, the RCD itself must be declared defective and replaced.
The RCD trips out when it should not. The leakage currents are probably too high. First disconnect all loads from the network
on which you are performing the test. Then perform a second test with the current reduced (in UF check) as far as possible.
If the problem persists, the RCD must be declared defective.

3.12. CURRENT AND LEAKAGE CURRENT MEASUREMENT
A
TEST
This measurement requires the use of a specific optional current clamp.
It can measure very low currents (of the order of a few mA) like fault currents or leakage currents, and high currents (of the order
of a few hundred Amperes).
3.12.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The specific clamps operate on the current transformer principle: the primary is constituted by the conductor in which the current is
to be measured, while the secondary is constituted by the internal winding of the clamp. This winding is itself closed through a resistance having a very low value, located in the device. The voltage across the terminals of this resistance is measured by the device.
Two of the four points of connection of the clamp serve to identify the type of clamp (x 1,000 or x 10,000) and the other two to
measure the current. Knowing the ratio of the clamp, the device displays a direct reading of the current.

The current measured by the clamp is too low. Use a clamp having a lower ratio or pass the conductor through the clamp
several times to increase the measured current.
Here, the conductor passes through the clamp 4 times. You will
have to divide the measured current by 4 to know the true value
of I.

TEST
This measurement requires the use of the optional specific MN77 current clamp. It can be made on a single-phase network or
on a three-phase network that is balanced in voltage and in current.
3.14.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
For a single-phase network, the device measures the voltage between the L and PE terminals, then multiplies it by the current
measured by the clamp.
For a three-phase network balanced in voltage and in current, the device measures one of the three phase-to-phase voltages, multiplies it by the current of the third phase, then multiplies the result by √3. Example: P3f = U12 x I3 x √3

3.14.5. POWER FACTOR
In the case of sinusoidal signals, the sign of cos j indicates whether the measurement is being made on a generator (cos j <
0) or on a receiver (cos j > 0). The power factor, PF, can be regarded as equivalent to cos j but generalized to non-sinusoidal
signals, which is often the case with currents.
However, on the instrument, the sign of the PF is treated conventionally, meaning that it indicates only the phase advance or delay
(inductive or capacitive load) and not whether a receiver or a generator is involved.
The phase angle is counted algebraically. It represents the angular difference of the voltage vector with respect to the current
vector, taken as reference.

3.14.6. ERROR INDICATION
The commonest errors in the case of a power measurement are:
The voltage is outside the measurement range.
The frequency is outside the measurement range.
The current is too low to be measured.
The power measured is negative. Check that the clamp is correctly placed on the cable (look at the direction of the arrow). If
it is it means that, what you are measuring is power returned (from receiver to generator).

TEST
This function is used to display the harmonic analysis of a voltage or current of which the signal is steady-state or quasi-steadystate. It is used to establish a first diagnostic of the harmonic pollution of an installation.
The current analysis requires the use of the MN77 current clamp (optional).
3.15.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE
The device measures the voltage and, if the clamp is connected, the current. Then, depending on what the user has chosen (FFT U
or FFT I), it performs an FFT limited to the first 50 harmonics either of the voltage or of the current. Harmonic 0 (the DC component)
is not displayed.

3.16. COMPENSATION FOR THE RESISTANCE OF THE MEASUREMENT LEADS
R∆
0
Compensation for the resistance of the measurement leads serves to neutralize their values and obtain a more accurate measurement when the resistance to be measured is low. The cords are already compensated in the plant; you must perform a new
compensation if you use cords other than those provided.
The device measures the resistance of the accessories (leads, probe tips, crocodile clips, etc.) and subtracts this value from the
measurements before displaying them.
Compensation for the resistance of the measurement leads is possible in continuity, 3P earth, and loop tests. It is different for
each of these functions. It must be renewed at each change of accessories.
Press the key to enter the function.
The current value(s) of the compensation is(are) displayed at top right. A value of zero indicates that no compensation has
been determined. The

Proceed as for compensation, but rather than short-circuiting the leads, leave them disconnected. Then press the TEST button.
The device removes the compensation, then returns to voltage measurement. The
symbol disappears from the display unit
and the icon is crossed out.
3.16.5. ERROR
If the resistance of the measurement leads is too high (>2.5 W per lead), compensation is impossible. Check the connections
and any junctions and leads that might be open-circuit.
If, during a continuity, 3P earth, or loop impedance measurement, you obtain a negative measurement result, you must have
changed the accessories without redoing the compensation. In this case, perform a compensation with the accessories you
are now using.

3.17. ADJUSTMENT OF THE ALARM THRESHOLD
The device makes an audible signal and the indicator flashes:
in continuity, resistance and insulation measurement, if the measurement is below threshold;
for earth and loop measurements and measurements of the voltage drop in the cables, if the measurement is above threshold;
for short-circuit current measurements, if the measurement is below threshold;
in test of residual current device, if the measurement is not between the two thresholds (Tmin and Tmax).
In continuity measurement, the audible signal is used to validate the measurement.
In all the others functions, it reports an error.
The alarm threshold is adjusted in essentially the same way for all measurements.

4.3. PRESENCE OF DANGEROUS VOLTAGE
The voltage is regarded as dangerous from 25, 50, or 65V, depending on the value of UL programmed in SET-UP.
For measurements made without voltage (continuity, insulation, and 3P earth), if the device detects a voltage, it
disables starting of the measurement by the pressing of the TEST button and displays an explanatory error message.
For measurements that are made on live circuits, the device detects the absence of voltage, the absence of a protective conductor, a frequency or voltage outside the measurement range. When the TEST button is pressed, the device then disables starting
of the measurement by the pressing of the TEST button and displays an explanatory error message
4.4. INVALID MEASUREMENT
If the device detects an error in the measurement configuration or in the connection, it displays this symbol and a
corresponding error message.

6. MEMORY FUNCTION
6.1. ORGANIZATION OF THE MEMORY AND NAVIGATION
The device has 1000 memory locations to record measurements. They are organized in a tree on three levels, as follows:
SITE 1
ROOM 1
OBJECT 1
OBJECT 2
ROOM 2
OBJECT 1
SITE 2
ROOM 1
...
Navigation in the tree is done using the directional keypad. The titles of the SITES, ROOMS, and OBJECTS can be parameterized by the user.
If a SITE or ROOM is preceded by the sign, it means that this level has sub-levels that can be expanded using the key or
the OK key. The sign is then replaced by the sign.
To compress the tree (change from the sign to the sign), use the or OK key.
Measurements are always recorded on an OBJECT. In the OBJECT, measurements are classified by TYPE OF TEST (continuity,
insulation, loop, etc.). Each OBJECT can contain up to nine TESTS belonging to the same TYPE OF TEST. Each TEST corresponds
to one measurement.
To see the tests contained in an OBJECT, go to the OBJECT and press the OK key.
A status symbol displayed to the right of the OBJECTS, of the TYPES OF TEST, and of the TEST indicates:
that the OBJECT has not yet been tested,
that all TESTS of the OBJECT are OK,
that at least one TEST of the OBJECT is not OK.
6.2. ENTERING THE STORAGE FUNCTION
When a measurement is over, the device proposes recording it by displaying the recording icon (arrow pointing in) at bottom left
of the measurement results:
The percentage indicates the level of occupancy of the memory.

7. DATA EXPORT SOFTWARE
The data export software is in two parts:
ICT (Installation Controller Transfer), used to configure the parameters of the measurements, prepare the tree in memory, and
export the recorded measurements in an Excel file.
Dataview, used to recover the measurements from the Excel file and present them in the form of a report conforming to the
standard in your country.
Start by installing the driver and the software programs using the CD provided with the C.A. 6116.
Then, turn the device on by turning the switch to
any setting.
SET UP
Then connect the device to the PC using the USB cord
provided with the instrument and removing the cover
that protects the USB port of the device.
When the device is in communication with a PC, it
does nothing else and its keys are inactive. It then
displays the following message:

8.4. INTRINSIC UNCERTAINTY AND OPERATING UNCERTAINTY
The installation testers complie with standard IEC-61557, which requires that the operating uncertainty, called B, be less than 30%.
In insulation, B = ± ( |A| + 1,15 √ E1² + E2² + E3² )
with A = intrinsic uncertainty
E1 = influence of the reference position ± 90°.
E2 = influence of the supply voltage within the limits indicated by the manufacturer
E3 = influence of the temperature between 0 and 35°C.
In continuity measurement, B = ± ( |A| + 1,15 √ E1² + E2² + E3² )
In loop measurement, B = ± ( |A| + 1,15 √ E1² + E2² + E3² + E6² + E7² + E8² )
with E6 = influence of the phase angle from 0 to 18°.
E7 = influence of the network frequency from 99 to 101% of the nominal frequency.
E8 = influence of the network voltage from 85 to 110% of the nominal voltage.
In earth measurement, B = ± ( |A| + 1,15 √ E1² + E2² + E3² + E4² + E5² + E7² + E8² )
with E4 = influence of the interference voltage in series mode (3 V at 16.6, 50, 60, and 400 Hz)
E5 = influence of the resistance of the rods from 0 to 100 x RA but ≤ 50 kW.
In test of residual current device, B = ± ( |A| + 1,15 √ E1² + E2² + E3² + E5² + E8² )
with E5 = influence of the resistance of the probes within the limits indicated by the manufacturer.
8.5. POWER SUPPLY
The device is powered by a10.8 V 5.8 Ah rechargeable Lithum-ion battery pack.
8.5.1. LITHIUM-ION TECHNOLOGY
The Li-ion technology has many advantages:
long life between charges with limited bulk and weight,
no memory effect: you can recharge your battery even if it is not fully discharged, without reducing its capacity,
very low self discharge,
the possibility of recharging your battery rapidly,
protection of the environment through the absence of polluting materials such as lead and cadmium.
8.5.2. BATTERY CHARGE
The instrument is not designed to operate when the charger is connected. The measurements must be made using battery
power.
The battery charger of the device is in two distinct parts: an external power supply and a charger built into the device.
The charger manages the charging current, the battery voltage, and the internal temperature of the battery simultaneously. This
optimizes charging while guaranteeing a long battery life.
The day before you use your device, check its charge condition. If the battery level indicator shows less than three bars, charge
the device overnight (see §1.2).
The charging time is approximately 5 h.
In order to extend the life of your battery:
Use only the charger supplied with your device. The use of another charger may prove dangerous!
Charge your device only between 0 and 45°C.
Observe the conditions of use and storage stated in this data sheet.
Following prolonged storage, the battery may be fully discharged. In this case, the first charge may take longer.
89
Set the switch to OFF; charging is possible when the device is not off, but will take longer.
8.5.3. OPTIMIZE BATTERY CHARGING
During charging, the temperature of the battery rises, especially towards the end. A safety device, built into the battery, checks
constantly that the battery temperature does not exceed an acceptable maximum. If this maximum is exceeded, the charger
switches off automatically, even if charging is not complete.
The battery is at the bottom of the device, and the evacuation of the heat can be facilitated by placing the device upright while
charging. The battery temperature is then lower and it will be charged more fully.
This precaution is especially important when the air temperature is high (in summer).
8.5.4. LIFE BETWEEN CHARGES
The mean battery life depends on the type of measurement and on how the device is used. Approximately:
12 h if the automatic switching off function is deactivated,
24 h if the automatic switching off function is activated,
How long your device can operate when the battery is fully charged depends on several factors:
The consumption of the device, which depends on the measurements you make,
The capacity of the battery. It is greatest when the battery is new, and declines as the battery ages.
Here are a few ways to extend battery life between charges:
Use the back-lighting only when it is strictly necessary,
Set the brightness of the display to the lowest level at which you can still read the display unit,
Program the shortest time to automatic switching off you are comfortable with (see SET-UP, § 5),
Use the pulse mode for continuity measurements at 200 mA,
If the continuity measurement at 200 mA is made in permanent mode, do not let the measurement leads touch each other
when you are not making a measurement,
When making insulation measurements at high test voltages, stop pressing the TEST button when the measurement is over.

8.5.5. END OF BATTERY LIFE
The internal resistance of a battery at the end of its life is high. The result is an abnormally short charging time.
After a full charge, the device indicates “charging over”, but as soon as the charger is disconnected, the display unit loses its
contrast and goes off, meaning that the battery no longer holds a charge.
8.6. ENVIRONMENTAL CONDITIONS
Indoor and outdoor use.
Specified operating range 15 -20 to 60°C and 10% to 85% RH
Range for recharging the battery 10 to 45°C
