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; temperature, relative humidity,
altitude, level of pollution, and location.
• Before each use, check the integrity of the insulation on the
sensor, cable and housing. Do not use the instrument if it is
open, damaged, poorly assembled, or if its accessories appear
damaged.
• The sensor must not be applied to or removed from uninsulated
conductors at dangerous voltages.
• Use personal protection equipment systematically.
• All troubleshooting and metrological checks must be
performed by competent and accredited personnel.

CHAPTER 2
PRODUCT FEATURES
2.1 Description
An ideal addition to the electrician’s tool kit, the Digital FlexProbe®series
can be used for TRMS AC current measurements from 20mA to 4000A,
and are rated 600V CAT IV. They provide a welcomed solution when
accessing electrical conductors is difficult and in tight places.
Two models are available. The Model 400D, available with a 6", 10", or 24" sensor, has a measurement range starting at 20mA, and is
designed for work in residential, commercial and light industrial
applications. It can be used to check electrical distribution systems up
to 400A.
The Model 4000D, available with a either a 14" or 24" sensor, has a
measurement range starting at 100mA and can be used on higher-
power industrial installations, as well as electrical utilities for
measurements up to 4000A.
Although they are high-performance instruments, the Digital
FlexProbe®series are very simple to use: two buttons are all it takes
to start the instrument, deactivate the auto power-off, HOLD the value
on the display or store the maximum value (MAX HOLD). The values are
read directly on the built-in 4000-count display.
They are ergonomically designed for comfortable handheld use
even when bulky gloves are required. The optional articulating,
magnetic Multifix mounting system accessory makes it simple to hang
on a wall, door, table edge or clip onto a belt.

OPERATION
3.1 Measurement Principle
The flexible sensor is based on the Rogowski coil.
This principle combines:
• Excellent linearity with no saturation effect (therefore no heating)
• Light-weight (no magnetic circuit)
3.2 Use
3.2.1 Connection
1. Pressthelockingclip(s)toopenthesensor.
2. Placethesensoraroundtheconductorthroughwhichthecurrentto

If the measurement exceeds the display capacity (4000A), the device dis-
plays 3999, blinking.
A
If the measurement is too low (see § 3.2), the device displays dashes.
A
If the edges of the signal are too steep, or its peak factor is too large, the
device displays OL.

3.2.3 Freezing the Measurement
If you want to freeze the display of a measurement, press the HOLD
button. The HOLD symbol is displayed.
HOLD

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

3.2.4 Search for Maximum
To search for a maximum, for example a spike lasting at least 100ms,
press the HOLD (MAX > 2s) button for more than two seconds.
The Max symbol will display and the instrument will begin measuring.
M AX
A
The Digital Flexprobe®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)
button again.
3.2.5 Auto Power OFF
If there is no activity after 10 minutes, the Digital Flexprobe®turns off
automatically (unless the MAX function is active) to preserve battery life.
To deactivate the Auto Power OFF feature, press the and HOLD
buttons simultaneously when turning the instrument on.
To reactivate automatic switching off, switch the device off, then back on.
3.2.6 Low Battery
When the battery voltage drops and the remaining battery life of the
instrument is approximately one hour, the symbol blinks on the
display.
When the battery voltage is too low to guarantee the accuracy of a
measurement, the symbol lights steadily. The batteries must then be
replaced (see § 5.2).
3.2.7 Disconnecting
Turn off the device by pressing the button. Press the yellow opening
lever to open the flexible sensor. Remove the sensor from the conductor.
