PRECAUTIONS FOR USE

This instrument is protected against voltages of not more than 1000V with respect to ground in measurement category III or 600V in CAT IV between the sensor and the conductor of which it measures the current.

The protection provided by the instrument may be impaired if the instrument is used other than as specified by the manufacturer.

• Do not exceed the rated maximum voltage and current or the measurement category.

• Observe the conditions of use, namely the temperature, the relative humidity, the altitude, the level of pollution, and the place.
  Before each use, check the integrity of the insulation on the coil, the cords and the housing. Do not use the instrument if it is open, damaged, or poorly reassembled, or its accessories if they appear damaged.

1. PRESENTATION

The DigiFLEX is used for RMS measurements of current, from 20mA to 400A .

The sensor takes the form of a flexible coil 17 or 25cm long, connected by a shielded cord to a small housing containing the signal processing electronics, supplied by a battery.

The flexibility of the sensors makes it easier to wrap them round the conductor to be measured, whatever its type (cable, bar, strand, etc.) and its accessibility. The design of the snap-action coil opening and closing device allows it to be handled while wearing protective gloves.

On the back of the electronics housing is a notch for the attachment of a belt clip (optional).

The multi-function belt clip can be used:

to carry the electronic housing on your belt,

to attach it to a metal surface using the built-in magnet,

to hook it to a door or the edge of a table.

2. CURRENT MEASUREMENT

2.1. MEASUREMENT PRINCIPLE

The flexible sensor is based on the Rogowski coil.

It combines:

very good linearity with no saturation effect (and so no heating);
light weight (no magnetic circuit).

2.2. USE

2.2.1. CONNECTION

First of all, use the appropriate means of protection.

Press the yellow opening device to open the flexible coil.

Open it, then place it round the conductor through which the current to be measured flows (only one conductor in the sensor).
Close the coil.

In order to optimize measurement quality, it is best to centre the conductor in the coil and to make the shape of the coil as nearly circular as possible.

Press the key to switch the device on. The display unit lights.

2.2.2. MEASUREMENT

Read the measurement on the display unit. The current is given in ARMS.

If the measurement exceeds the display capacity (400 A), the device displays 399.9, blinking.

If the measurement is too low (see § 3.2), the device displays dashes.

If the edges of the signal are too steep or its peak factor is too large, the device displays OL.

2.2.3. FREEZING THE MEASUREMENT

If you want to freeze the display of a measurement, press the HOLD key.

The HOLD symbol is displayed.

The device continues to make measurements, but the display is frozen. To release it, press the HOLD key again.

2.2.4. SEARCH FOR MAXIMUM

To search for a maximum, for example a spike lasting at least 100 ms, press the HOLD (MAx > 2s) key for more than two seconds.

The Max symbol is then displayed; the device starts making measurements a few seconds later.

The device compares each new measurement to the one displayed. If the new measurement is greater than the old, it replaces it in the display.

To return to the real-time display mode, press the HOLD (MAx > 2s) key again.

2.2.5. DE-ACTIVATION OF AUTOMATIC SwITCHING OFF

In order to save the batteries, the device switches itself off automatically at the end of 10 minutes if the user has not pressed a key (unless the Maxx function is active).

It is possible to deactivate automatic switching off. To do this, when you switch the device on, press the and HOLD keys simultaneously. The P symbol (lit steadily) is then displayed.

To reactivate automatic switching off, switch the device off, then back on.

2.2.6. BATTERIES LOW

When the battery voltage drops and the remaining battery life of the device is only about one hour, the - + symbol blinks on the display unit.

When the battery voltage is too low to guarantee the accuracy of the measurements, the - + symbol lights steadily. The batteries must then be replaced (see 4.2

2.2.7.DISCONNECTING

Switch the device off by pressing the key.
Press the yellow opening device to open the flexible core.
Remove the flexible core from the conductor.
