3. PROCEDURE
3.1. GENERAL
When it leaves the plant, the device is configured so that it can be used without changing the parameters. For most meas-
urements, 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, 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.

12
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.

L
: the phase is on the left-hand contact of the mains plug when the white spot is up.

L
: 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.
3.2.2. MAKING A MEASUREMENT
Connect the leads to the device to be tested. As soon as the device is powered up, it measures the voltages present on its ter-
minals and displays them, whatever the setting of the switch.

13
Choice of measurement current: kW, 12 mA or 200 mA.
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 kWis used to make resistance measurements up to 400 kW.
SET UP
OFF
R
To correct for the resistance of the measurement leads (leads and probe tips or alligator clips), for measurements
at 12 and 200 mA (see §3.13).
Pressing the TEST button starts only one measurement (pulse mode).
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 Wand
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 Wand 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 compen-
sate 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 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 un-
necessary 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 ter-
minals of the device. The object to be tested must not be live.
Pressing the TEST button starts the continuous measurement (permanent mode). To
stop it, you must press the TEST button again.
3.3.3. CONFIGURING THE MEASUREMENT
Before starting the measurement, you can configure it by modifying the parameters displayed:

3.3.5. ERROR INDICATION
The commonest error in the case of a continuity 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 continuity measurement is not enabled. Eliminate the cause of the interference voltage and start the measure-
ment 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 MWterminals. The value of this voltage depends on the resistance
to be measured: it is greater than or equal to UNwhen R is greater than or equal to 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 MWterminal 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 un-
necessary 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.
To avoid leakage during the insulation measurement, which would
throw off the measurement, do not use the measuring cable when
you make this type of measurement, but two simple leads.
Generally, an insulation measurement on an installation is made between the interconnected phase(s) and neutral, on the one
hand, and earth, on the other.

3.4.5. ERROR INDICATION
The commonest error in the case of an insulation measurement is the presence of a voltage on the terminals. If it is greater than
50 V, the insulation measurement is not enabled. Eliminate the voltage and start the measurement over.
The measurement may be unstable, probably because of an overly capacitive load or an insulation fault. In this case, read the
measurement on the bargraph.

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 additional 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 instal-
lation), the earthing strip of the installation must be open during the measurement.
It is possible to make a rapid measurement and measure only REor else to make a more detailed measurement by also measur-
ing 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 meas-
ures 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 RSand RHrods, 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 UP
OFF
Connect the cables to the H and S terminals. Power down the installation and disconnect the earth strap. Then connect the E
terminal to the earth electrode to be checked.
The alarm, if activated, serves to inform the user, by an audible signal, that the measurement is above threshold, making it un-
necessary 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:
62% d
d
HS
To compensate for the resistance of the lead connected to the E terminal, for measurements of low values (see §3.13).
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 cables, placing them as far apart as possible, and not making loops.
Choice of type of measurement: rapid, to measure RE only (icon crossed out), or detailed, to measure also rod
resistances RSand RH. This last case is useful if the ground is dry, making the resistance of the rods high.
