1. PRESENTATION

1.1. GENERAL

MiniFlex® sensors take the form of a flexible coil connected by a shielded lead to a housing containing the signal processing electronics, powered by batteries.

The flexibility of the sensors facilitates the clamping of the conductor to be measured, whatever its nature (cable, bar, strand, etc.) and its accessibility. The design of the coil opening and closing device, by snap locking, allows handling while wearing protective gloves.

The electronic unit can be connected to the mVac or Vac input of a measuring instrument having an input impedance of ≥ 1 M .

1.2. SINGLE-PHASE MINIFLEX®

MiniFlex ^® series MA110 single-phase sensors constitute a line of three models, 17, 25, and 35 cm long, that convert alternating currents ranging from 3 to 3000 A into proportional AC voltages.

Flexible coil. Sensor opening device. Shielded cord. Switch to activate the instrument and choose the sensitivity. Auto Power Off button to deactivate automatic switching off. Type B Micro-USB port to connect a 5V power supply. 2 banana plugs, dia. 4 mm. Red OL indicator reporting an overshoot of the measurement range (overload). Orange Auto Power off indicator indicating that automatic standby switching of the device is activated. Green On indicator indicating that the device is on (blinking) or connected to the optional mains adapter (steady). Connecting cord between the electronic unit and a display device.

1.3. THREE-PHASE MINIFLEX®

The MiniFlex ^® series MA130 sensor converts alternating currents ranging from 30 to 3000 A into proportional AC voltages. It comprises 3 sensors 25 cm long connected to the electronic unit. The output is via 3 BNC connectors on which it is possible to place the adapters provided in order to obtain outputs with 2 safety plugs.

The three outputs of the electronic unit can be connected to a standard wattmeter (as auxiliary inputs), to multimeters, to a recorder, etc.

L1 L2 L3 3 current sensors for 3 phases. 3 BNC / safety plugs (19 mm centres) adapters. L1 L2 L3 3 BNC connectors, each corresponding to a sensor. MA 130 ACOS/NEUTRAL 800 V CAT III

The multimeter or instrument connected must have a maximum voltage and a measurement category at least equal to those of the MiniFlex® sensor, since otherwise the maximum voltage and category of the assembly will be those of the lowest-rated component.

2. CURRENT MEASUREMENT

2.1. MEASUREMENT PRINCIPLE

The sensors use the principle of the Rogowski coil.

The sensor used achieves:

■ very good linearity and no saturation effect (and so no overheating);
■ a wide measurement dynamic, up to several kA;
■ insensitivity to DC (measurement of the AC component of any AC + DC signal);
■ light weight (no magnetic circuit).

2.2. USE

2.2.1. CONNECTING THE MA110

Connect the output leads to a measuring instrument having an input impedance ≥ 1 M . Switch it on and set to AC voltage measurement.

0 mV VAC COM+ black red

Put the electronic unit into operation by turning the switch to some position. The green On indicator starts blinking.

Press on the yellow opening device to open the flexible coil.

Diagram showing a hand holding a circular device with a red arc, before and after adjustment, indicating a change in the device's position.

Open it and place it around the conductor carrying the current to be measured (only one conductor in the sensor). Close the coil. You must hear the "click".

In the case of an uninsulated conductor at a dangerous voltage, use individual protection equipment.

Diagram illustrating a medical procedure on a device, showing a cable being inserted into a device before and after treatment.

To optimize measurement quality, centre the conductor in the coil.

Set the switch of the electronic unit to the range providing the best sensitivity and check that the red OL indicator is off (saturation of the electronics entailing a measurement error).

Read the measurement on the multimeter, applying the reading coefficient indicated on the label on the electronic unit corresponding to the setting of the switch.

3 A\~ range 1000 mV\~/A\~

30 A\~ range 100 mV\~/A\~

300 A\~ range 10 mV\~/A\~

3000 A\~ range 1 mV\~/A\~

Multiply the reading by the coefficient.

For example, a reading of 1 V on the measuring instrument corresponds to a current of 1 V10 mV/A = 100 A in the 300 A\~ range.

2.2.2. DISCONNECTING THE MA130

Withdraw the flexible coil from the conductor, set the switch to OFF, and disconnect the electronic unit from the multimeter.

2.2.3. IDENTIFYING THE SENSORS OF THE MA130

To identify the sensors and the output leads, you can mark them with the coloured rings provided with the device.

Clip rings of the same colour on the sensor and on the corresponding output leads.

2.2.4. CONNECTING THE MA130

Proceed as for the MA110:

■ Connect the output leads to a measuring instrument.
■ Put the electronic unit into operation by turning the switch to some position. The green On indicator starts blinking.

■ Open the 3 sensors and place them on the 3 phases.

L3 L2 L1 L1 L2 L3

■ Set the switch on the electronic unit to the range providing the best sensitivity and check that the red OL indicator is off (saturation of the electronics entailing a measurement error).
- Read the measurement on the display device and apply the reading coefficient indicated on the label on the electronic unit corresponding to the setting of the switch.

30 A\~ range 100 mV\~/A\~

300 A\~ range 10 mV\~/A\~

3000 A\~ range 1 mV\~/A\~

2.2.5. DISCONNECTING THE MA130

Withdraw the 3 sensors from the 3 conductors, set the switch to OFF, and disconnect the electronic unit from the display device.

2.2.6. AUTOMATIC SLEEP MODE

When the device is started up, it operates for 10 minutes, then automatically switches itself to sleep mode in order to save the batteries.

To report that the automatic power off function is active, the orange Auto Power Off indicator is lit.

P Auto Power Off

It is possible to override automatic power off. This is done by switching the device on by turning the switch to one of the measurement positions and at the same time pressing the Auto Power Off button for more than 2 seconds. The orange Auto Power Off indicator remains off.

> 2s OFF

2.3. MAINS ADAPTER (OPTION)

For long-duration measurements, it is possible to connect the electronic unit to line power.

Withdraw the protection from the type B micro-USB connector, then connect the lead. You can use any mains/micro-USB adapter that delivers 100 mA or more.

>90 VAC < 264 VAC 50 / 60 Hz

The green On indicator remains on but its brightness varies to indicate that the batteries are OK.

graph TD
    P((P)) --> AutoPowerOff["Auto Power Off"]
    AutoPowerOff --> OL((OL))
    AutoPowerOff --> On((On))

While the external power supply is present, automatic power off is disabled. But if the supply is cut off, the batteries take over and automatic power off acts at the end of 10 minutes.

If you make long-duration records, you must deactivate automatic power off (see § 2.2.6).

The insulation between the type B micro-USB connector and the measurement output is 1000 V CAT III or 600 V CAT IV. That makes it possible to connect the device without risk to wattmeters having uninsulated inputs. The type B micro-USB connector must not be in contact with conductors or uninsulated parts at dangerous voltages
