Measurement category II corresponds to measurements
taken on circuits directly connected to low‑voltage
installations.
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.
Thank you for purchasing a DigiFLEX MA4000D current
meter with flexible sensor.
For best results from your instrument:
read this user’s manual carefully,
comply with the precautions for use.

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.
The sensor must not be applied to or removed from
uninsulated conductors at dangerous voltages.

1. PRESENTATION
The DigiFLEX is used for RMS measurements of current,
from 200 mA to 4000 A.
The sensor takes the form of a flexible coil 35 cm 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.

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.
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.

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 A
rms
.

If the measurement exceeds the display capacity (4000 A),
the device displays 3999, 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 M
ax
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.
A
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.

8
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 MAX 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 Psymbol (lit steadily) is then dis‑
played.
A
P
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 accu‑
racy 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.

1. PRESENTATION
DigiFLEX används för TRMS mätningar av ström, från
200 mA till 4000 A.
Sensorn har formen av en flexibel spole 35 cm lång, anslu‑
ten med en skärmad kabel till ett litet hölje som innehåller
elektronik för signalbehandling, strömförsörjd med ett batteri.
Spolens flexibilitet gör det lätt att omsluta den runt ledaren
som skall mätas, oavsett typ (kabel, skena etc.) och dess
tillgänglighet. Utförandet med snäppteknik för öppning och
stängning av spolen gör att den kan hanteras även med
skyddshandskar.

Multi‑funktions bältesklämman kan användas till:
Att bära elektronikhöljet på bältet,
Att fästa elektro‑
nikhöljet på en

2. STRÖMMÄTNING
2.1. MÄTPRINCIP
Den flexibla spolen är baserad på Rogowski spolen.
Den kombinerar:
mycket god linjäritet utan mättnadseffekt (och ingen
värme);
låg vikt (ingen magnetisk krets).
2.2. ANVÄNDNING
2.2.1. ANSLUTNING
Först av allt, skydda dig på lämpligt sätt.
Tryck på den gula öppningsanordningen för att öppna
den flexibla spolen.

Öppna den och placera den runt den ledare som skall mätas
(endast en ledare i spolen).
Stäng spolen.
För att optimerad mätkvaliteten, är det bäst att centrera
ledaren i spolen och göra formen på spolen så nära cir‑
kulär som möjligt.
Tryck på tangenten för att slå på strömtången.
Displayenheten tänds.
2.2.2. MÄTNING
Läs mätresultatet på displayenheten. Strömmen anges i
