PRECAUTIONS FOR USE
This device is compliant with safety standard IEC 61010-2-030, the leads are compliant with IEC 61010-031, and the current sen­sors are compliant with IEC 61010-2-032, for voltages up to 600 V in category IV or 1,000 V in category III.
Failure to observe the safety instructions may result in electric shock, re, explosion, and destruction of the instrument and of the
installations.
 The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken
in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.
If you use this instrument other than as specied, the protection it provides may be compromised, thereby endangering you.
 Do not use the instrument on networks of which the voltage or category exceeds those mentioned.
 Do not use the instrument if it seems to be damaged, incomplete, or poorly closed.
 Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation
is deteriorated (even partially) must be set aside for repair or scrapping.
 Before using your device, check that it is perfectly dry. If it is wet, it must be thoroughly dried before being connected or being
operated in any way.
 Use only the leads and accessories supplied. Using leads (or accessories) of a lower voltage or category reduces the voltage
or category of the combined instrument + leads (or accessories) to that of the leads (or accessories).
 Use personal protection equipment systematically.
 Keep your hands away from the terminals of the device. When handling the leads, test probes, and crocodile clips, keep your ngers behind the physical guard. Use only the battery pack supplied by the manufacturer. This pack includes specic safety features.
 Some current sensors must not be placed on or removed from bare conductors at hazardous voltages: refer to the sensor
manual and comply with the handling instructions.

Precautions for use
These safety instructions must be respected to assure the personal safety and the environment of use. If you do not comply with them, there is a risk of electric shock, explosion or re. If you use these instruments other than as specied or without observing the elementary safety rules, the protection they provide may be compromised, endangering you. The safety of any system which may include these leads or accessories is the respo
assembler of the system.
Each time before use, always check that the insulation of the leads or accessories is in good
condition. Any element whose insulation is damaged (even partially) must be removed from use and scrapped. A change of color of the insulating material is an indication of deterioration.
The steady-state voltages, currents, and measurement categories are marked on the instruments, on
the cords, and on the accessories. Comply with these values.
Use specic individual safety protections w
zardous live parts can be accessible in the
hen ha
installation where the measure is performed
Before using your instrument, check that it is in good working order (for example, by measuring a
known dangerous voltage).
If the manual states how to replace the fuse(s) of your instrument, use only the recommended fuses. Before replacing the batteries (rechargeable or not), disconnect the leads of your instrument.
The use of a measurement instrument, a lead or an accessory with a lower category or voltage downgrades the use of the assembly (instrument + lead + accessory) to the lowest category and/or operating voltage.
Using a measuring instrument in a category II or III or IV environment can be dangerous. In such measurement environments, the operators must be trained and/or accredited and/or informed of the safety measures to be taken.
Measurement categories:
CAT II: Measurement category II is for measurements performed on circuits directly connected to the
low voltage installation
Examples: measurements on household appliances and portable tools.
CAT III: Measurement category III is for measurement performed in the building installation
Examples: distribution boards, circuit
-breakers, machine or industrial equipment with permanent
connection to the xed installation.
CAT IV: Measurement category IV is for measurements performed at the source of the low-voltage installation.
Example: meters and measurements on primary overcurrent protection devices and ripple control units.
Cleaning
Disconnect the leads or the test accessories Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry rapidly with a dry

2.3. ON/OFF SWITCH

The device can operate either on its battery or on mains power. Pressing the button powers up the device. . If the device is shut off suddenly (line power outage in the absence of the battery) or automatically (battery low), an information message is displayed when it is next started up.
Pressing the switch again turns the device off. If the device is recording, metering energy, or searching for transients, alarms,
and/or inrush current acquisition, it requests conrmation.
Select Yes or No on the corresponding yellow keys, then press the key to validate.
 If No is selected, recording will continue.  If Yes is selected, the data recorded until that point are nalized and the device is turned off.

2.6. CONNECTORS

2.6.1. CONNECTION TERMINALS
These are located on one side of the housing. Each terminal is protected by a plug. The plugs must be removed to connect the leads, then stowed in the pouch in the cover of the device.
In order to keep the device water- and air-tight and the terminals clean, put the plugs back on the unused terminals.
The terminals let the operator:
 screw special leads in place to ensure total water-tightness  or to connect standard leads that are slightly less water-tight.

4.7. SENSORS AND RATIOS

Note: The ratios cannot be changed if the device is recording, metering energy, or searching for transients, alarms, and/or inrush
current acquisitions.
4.7.1. CURRENT SENSORS AND RATIOS
A rst screen A is used to dene the current sensors and ratios. It automatically displays the current sensor models detected by
the device. If a sensor is detected but not managed, an error message is displayed.
Figure 25: Current clamp and ratios screen in the Sensors and ratios menu
In the case of a 3-wire three-phase set-up where only two of the three current sensors required are connected, if these two sensors are of the same type and have the same ratio, the device simulates the third sensor by assuming the same characteristics as for the two others. The third sensor will be shown in the list as being simulated, or impossible to simulate otherwise.
The various current sensors are:
MN93 clamp: 200 A.
MN93A clamp: 100 A or 5 A.
C193 clamp: 1000 A.
J93 clamp : 3500 A.
AmpFlex®: 100, 6500 or 10000 A.
MiniFlex®: 100, 6500 or 10000 A.
PAC93 clamp: 1000 A.
E3N clamp: 100 A (sensitivity 10 mV/A).
E3N clamp: 10 A (sensitivity 100 mV/A).
Three phase adapter: 5 A.
If an MN93A clamp (5A range) or an Adapter is used, the current ratio setting is proposed automatically. If an MN93A clamp (5A range), an Adapter, an AmpFlex®, a MiniFlex®, or an E3N clamp is used, adjustment of the ratio, of the range, or of the sensitivity is proposed automatically.
Use the arrow keys (,, , ) to dene the transformation ratios between the primary current (1A to 60,000A) and the second- ary current (1A, 2A or 5A), then validate with the  key.
The primary current cannot be less than the secondary current.
4.7.2. VOLTAGE RATIOS
A second screen V or U, denes the voltage ratios.
The programming of the ratio or ratios can be different or the same for all or for some channels. The ratios to be programmed are phase-to-neutral voltage ratios when there is a neutral and phase-to-phase voltage ratios when there is not.
To change the ratios, press the  key.
