The USB port of the device is used to transfer the stored data to a PC. This operation requires the prior installation of a specific
peripheral driver and other software.
The USB cord and the associated software are supplied with the device.
3. Procedure
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 key.
However, you can also parameterize the measurements, using the function keys, or the device itself, using SET-UP.
In addition to an intuitive interface, the C.A. 6116 provides complete help in use and analyses and appraisals. Three types of help
function are available:

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 key.
3.1. Voltage measurement
3.1.1. Description of the measurement principle
Whichever function is chosen, the device always starts by measuring the voltage present on its terminals.
It 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 network 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 key.
3.1.2. 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 terminals and displays them, whatever the setting of the switch.
The mains socket outlet of the measuring cable is marked with a white reference spot.



L
L
: 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 phase is, probably because the PE is not connected or the L and PE conductors are interchanged.
Remark : the terminal identified as L is the one that has the highest voltage with respect to PE;
this does not mean that the other terminal is not at a dangerous voltage.
3.1.3. Error reporting
The only errors reported in voltage measurement are values outside the voltage and/or frequency measurement range. These
errors are reported in clear language on screen.
10
3.2. Resistance and continuity measurement
3.2.1. 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.
3.2.2. 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 permanent, 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 report, 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.

Before starting the measurement, you can configure it by modifying the parameters displayed:
Choice of measurement current: kW, 12 mA or 200 mA (default).
 The high current (200 mA) is used to measure only low resistance values, 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 alligator clips), for measurements
at 12 and 200 mA (see §3.14).
Pressing the TEST key starts only one measurement (pulse mode).
Pressing the TEST key starts the continuous measurement (permanent mode). To stop
it, you must press the TEST key again. The permanent mode is the default operating
mode.

3.2.4. Error reporting
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 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.

3.3. Insulation resistance measurement
3.3.1. Description of the measurement principle
The device generates a DC test voltage greater than the nominal voltage chosen UN 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 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.
3.3.2. Making a measurement
The alarm, if activated, serves to report, by an audible signal, that the measurement is below threshold, making it unnecessary
to look at the display unit to check this point.
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.
Set the switch to MW.

3.4. 3P earth resistance measurement
This function is used to measure an earth resistance with two additional rods, the third rod being constituted by the earth electrode to be tested.
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.
3.4.1. 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.
3.4.2. 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 cables, placing them as far apart as possible, and not making loops.

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 report, by an audible signal, that the measurement is above threshold, making it unnecessary
to look at the display unit to check this point.
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.
To compensate for the resistance of the lead connected to the E terminal, for measurements of low values (see

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.
19
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.
3.4.5. 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.

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.
3.4.6. Error reporting
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 15kW,
 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.


3.5. Loop impedance measurement (ZS)
In a TT type installation, the loop impedance measurement is an easy way to make an earth measurement without planting any
rods. The result obtained, ZS, is the loop impedance of the installation between the L and PE conductors. It is only very slightly
greater than the earth resistance, to which it adds the earthing resistance of the transformer and the resistance of the cables,
which are both negligible.
In a TN or TT type installation, the loop impedance measurement also makes it possible to calculate the short-circuit current and
size the protections of the installation (fuse or circuit-breaker).
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.
3.5.1. Description of the measurement principle
The device starts by generating pulses having a duration of 300 µs and an amplitude of at most 5 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 = ZL-PE = ZL+ZPE , and short-circuit current Ik = ULPE/ZS.
The value of Ik serves to check the proper sizing of the circuit-breaker.
For greater accuracy, it is possible to measure ZS with a high current (TRIP mode), but this measurement may trip out the installation.
3.5.2. 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.
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 terminals of the device.
SET UP
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.

The alarm, if activated, serves to report, by an audible signal, that the measurement is above threshold, making it unnecessary
to look at the display unit to check this point.
Smoothing the signal, rather than making several measurements and calculating a mean, yields a stable measurement directly.
But the measurement then takes longer.
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 (default)

 if 170<ULN<270 V: MEAS (default), 220 V, or 230 V.
 if 90<ULN<150 V: MEAS (default), 110 V or 127 V.

3.6. Measurement of the line impedance (Zi)
The loop impedance measurement Zi (L-N, L1-L2, or L2-L3 or L1-L3) is used to calculate the short-circuit current and size the protections of the installation (fuse or circuit-breaker), whatever type of neutral the installation uses.
3.6.1. Description of the measurement principle
The device generates pulses having a duration of 300 µs and an amplitude of at most 5 A between the L and N terminals. It then
measures the voltages UL and UN and from them deduces Zi.
The device then calculates the short-circuit current Ik = ULN/Zi the value of which serves to check the proper sizing of the protections of the installation.

3.7. Earth measurement on live circuit (Za, Ra)
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 an IT type installation, too, this measurement is a very simple way to measure the earth of frame grounds provided
that:
 the supply transformer is not isolated from earth but connected to it via an impedance,
 and the installation in not in a first fault state. Check the indication given by the PIT.
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 circuit-breakers, 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 §3.5) 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 = UPI-PE/I, I being the current
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
out the installation.
3.7.2. 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.
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 loop measurement can be made without modifying the connections
of the terminals of the device.
SET UP
If possible, first disconnect all loads from the network on which you make the earth
measurement on line circuit.
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.

3.8. Selective earth measurement on live circuit
This function is used to make an earth measurement and to select one earth from among others, in parallel, and measure it. It
requires the use of an optional current clamp.
3.8.1. Description of the measurement principle
The device starts by making a loop measurement ZS between L and PE (see §3.5) with a high current, and therefore with a risk of
tripping out the installation. This high current must be used to ensure that the current flowing in the clamp is large enough to be
measured. The device then measures the current flowing in the circuit surrounded by the clamp. Finally, it measures the potential
of the PE conductor with respect to the auxiliary rod and from it deduces RASEL = UPI-PE / ISEL, ISEL being the current measured by
the clamp.
3.8.2. Making a measurement
Connect the measuring cable to the device, then to the socket outlet of the installation to be tested.
Set the switch to ZS (RA/SEL.).
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 measurement can be made without modifying the connections of
the terminals of the device.

3.8.4. Error reporting ((loop, earth on live circuit, and selective earth on live circuit)
The commonest errors in the case of a loop impedance measurement or earth measurement on live circuit are:
 A connection error.
 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 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.
ATTENTION : the user may be charged with 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.

3.9. Test of residual current device
The device can be used to perform three types of test on residual current devices (or switches):
 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 RCD tripping current.
The test in pulse mode serves to determine the differential trip time.
The non-tripping test serves to check that the RCD does not trip out 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.
3.9.1. 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 ).
It therefore starts by generating a low current (<0.4 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 depending on the type of test requested), which will be the 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 or 0.3 IDN) so that the test current + 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 depending on the type 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. When the RCD opens the circuit, the device displays the exact value of the tripping
current and the trip 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, lasting at most 500 ms. And it measures the time the circuit-breaker 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 circuit-breaker must not open the circuit.
In all cases, if the circuit-breaker does not trip out, the device then sends a current pulse between the L and N terminals. If the
circuit opens, it means that the circuit-breaker was incorrectly installed (N and PE reversed).

3.9.6. Error reporting
The commonest errors in the case of a test of a residual current device are:
 The circuit-breaker did not trip out during the test. Now, to ensure the safety of users, a circuit-breaker must trip out within
300 ms, or 200 ms for a type S. Check the wiring of the circuit-breaker. If it is OK, the circuit-breaker itself must be declared
defective and replaced.
 The circuit-breaker 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 circuit-breaker must be declared defective.

3.10. Current measurement
This measurement requires the use of an 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).
3.10.1. Description of the measurement principle
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.

3.12.1. 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 opposite phase current, then multiplies the result by √3. Example: P3f = U12 x I3 x √3
3.12.2. Making a measurement

3.14. Compensation for the resistance of the measurement leads
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 device measures the resistance of the accessories (leads, probe tips, alligator 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.
Start by pressing the key to enter the function.
3.14.1. In continuity
R∆:
0.052
Ω
The current value of the compensation is displayed at top right. A value of
zero indicates that no compensation has been determined.
Connect the two leads that you are going to use for the measurement to
the W and COM terminals, short-circuit them, then press the TEST key.
The device measures the resistance of the leads and displays it. Press OK
to validate or
to keep the old value.
The R∆
0 , symbol, present on the bottom strip of the display unit, reminds
you that the resistance of the leads is compensated.
3.14.2. In 3P earth
R∆:
0.750
Ω
The current value of the compensation is displayed at top right. A value of
zero indicates that no compensation has been determined.
Connect the lead that you are going to use to connect the E terminal to the
earth between the H and E terminals, then press the TEST key.
The device measures the lead and displays its value. Press OK to validate
or
to keep the old value.
The R∆
0 , symbol, present on the bottom strip of the display unit, reminds
you that the resistance of the leads is compensated..

The current values of the compensations are displayed at top right. If the
values are zero, no compensation has been determined.
Connect the three leads that you are going to use for the measurement to
the L, N, and PE terminals, short-circuit them, then press the TEST key.
The device measures each of the three leads and displays their values.
Press OK to validate or
to keep the old value.
The R∆
0 , symbol, present on the bottom strip of the display unit, reminds
you that the resistance of the leads is compensated.
52
3.14.4. Eliminating the compensation
Proceed as for compensation, but rather than short-circuiting the leads, leave them disconnected. Then press the TEST key.
The device removes the compensation, then returns to voltage measurement. The R∆
0 symbol disappears from the display unit
and the
icon is crossed out.
3.14.5. 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.
3.15. Adjustment of the alarm threshold
The device makes an audible signal:
 in continuity, resistance and insulation measurement, if the measurement is below threshold;
 in earth and loop measurement, if the measurement is above 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.
Start by entering the alarm function by pressing the
or
key.
If the alarm is not active, press the

The value is outside the measurement range of the device. The minimum and maximum
values depend on the function.
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. 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.
4.5. Device too hot
The internal temperature of the device is too high. Wait for
the device to cool off before making another measurement.
This case concerns essentially the test of residual current
devices.

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 TYPE OF TEST, and of the TEST indicates:
 that the OBJECT has not yet been tested,
R that all TESTS of the OBJECT are OK,
T 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.

8.5. Power supply
The device is powered by a 9.6 V, 4 Ah rechargeable NiMH battery pack.
This has many advantages:
 long life between charges with limited bulk and weight,
 the possibility of recharging your battery rapidly,
 a very small memory effect: you can recharge your battery even if it is not fully discharged, without reducing its capacity,
 protection of the environment through the absence of polluting materials such as lead and cadmium.
The NiMH technology allows a limited number of charging/discharging cycles that depends on the conditions of use and the
charging conditions. Under optimum conditions, this number of cycles is 200.
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.
80
To make the most of your battery and extend its effectiveness:
 Use only the charger supplied with your device. The use of another charger may prove dangerous!
 Charge your device only between 10 and 35°C.
 Observe the conditions of use and storage stated in this data sheet.
The mean battery life depends on the type of measurement and on how the device is used. Approximately:
16 h if the automatic switching off function is deactivated,
24 h if the automatic switching off function is activated,
8.6. Environmental conditions
Indoor and outdoor use.
