■Description
This function is used to follow quick changes in the current,
such as a damped sinusoidal quantity, by measuring the
successive rms values calculated on ½, 1, 2½, 5 and 10
periods from the largest rms value computed and updated
on ½ period.
The applications are:
-Measurement of motor start-up currents
-Correct definition of fuses and circuit breakers (signal
amplitude-time relationship)
-Stress on components by current overload

The field of application is limited to industrial frequencies
(15 Hz... 70 Hz)

2. Integration of a “reference” period on one phase L1-L3
3. Calculation of the time delay between “reference” and
“measurement” periods enabling determination of the
phase order or phase rotation direction

request to prevent, for example, the unwanted or mistaken
integration of MIN/MAX values.

3.12.3Automatic compensation for cable resistance
This compensation is obtained by holding down the HOLD
key when the continuity test or measurement resistance
function is selected.
When the key is released, when the display shows zero, the
correction value is memorised in the clamp.
If the value measured is higher than 2 ΩΩ
ΩΩ
Ω, this correction is
stopped and the memorised correction value is reset to zero.
This correction is prohibited in MIN/MAX mode.
3.12.4Automaticcompensationofcurrentmeasurement zero
This compensation is obtained by holding down the HOLD
key when the current measurement function is selected.
When the key is released, when the display shows zero, the
correction value is memorised in the clamp.
If the value measured is higher than 6 A, this correction is
stopped and the memorised correction value is reset to zero.
This correction is prohibited in MIN/MAX mode.
3.12.5 Manual selection of AC or DC mode
Bydefaultthe clamp switchestoACor DCmodeautomatically
(AC or DC symbol flashing) for the V and A functions.
Short successive pressures on the yellow key are used to
select manually AC measurement, DC measurement and
return to automatic mode.
When the mode is selected manually, the AC or DC symbol
is fixed.
The selection of this manual mode is impossible in MIN/MAX
or HOLD mode.
3.12.6Selections possible in continuity function
By default the clamp is in continuity function ( ) for the
position corresponding to the rotary switch.
Successive presses on the yellow key enable selection of
the resistance measurement (Ω), then the semi-conductor
test function ( ) and return to the continuity function ( ).
3.12.7 Selection OF INRUSH function
This is done in function A (AC) by pressing first on the MIN/
MAX key then on the yellow key.
Consultation of the values corresponding to this function is
possible by pressing first on the HOLD key then by short
successive presses on the yellow key (see § 3.7) .
Quitting this function is possible by short presses on the MIN/
MAX key.
3.12.8 3.12.8 Suppression of automatic stop
Hold the HOLD key pressed and bring the rotary switch from
the OFF position to the position .
The unit emits a double beep then the
P
symbol flashes.
The selected configuration is memorised when the key is
released: the
P
symbol remains lit continuously.
The unit returns to automatic stop mode when the switch
goes to the OFF position.

3.12.9 Activation of the V-Live function
Hold the HOLD key pressed and bring the rotary switch from
the OFF position to the Vposition.
The unit emits a double beep then the V and symbol
flashes.
The selected configuration is memorised when the key is
released:theV symbol is then ON steady and the symbol
flashes.
Proceed in the same way to suppress theV-Live function: the
symbol then goes OFF when the key is released.
3.12.10 Modification of audio indication threshold in
continuity test
Hold the Yellow key pressed and bring the rotary switch from
the OFF position to the position .
The unit beeps, the Ω and symbols go ON along with the
threshold value (40.0 by default) .
Adjustment is then possible from 1 Ωto 40 Ωby successive
pressings on the yellow key (short pressure: progression of
1 Ωby 1 Ω; press and hold: progression of 10 Ωby 10 Ω).
Once the value is chosen, actuate the rotary switch to
memorise.
3.12.11 Default configuration of the unit
Hold the Yellow key pressed and bring the rotary switch from
the OFF position to A position.
The unit emits a double beep then all the segments of the
digital display and the symbol flash.
The default configuration is memorised when the key is
released: the display no longer flashes and the symbol
disappears.
The default configuration is:
- Audio identification threshold: 40 Ω
- Auto cut-off: with
- V-Live function: none
3.12.12 Date of last calibration carried out on unit
Hold the MIN/MAX key pressed and bring the rotary switch
from the OFF position to the Vposition.
The unit emits a beep, then the calibration date of the unit is
displayed in the form “week - year” (SS.AA) as long as the
MIN/MAX key is pressed.
3.12.13 Display of the internal software version
Hold the HOLD key pressed and bring the rotary switch from
the OFF position to the Aposition .
The unit beeps, the software version is displayed in the form
UX.XX for 2 seconds, then all the segments of the display
are shown as long as the HOLD key is pressed.
3.12.14 Showing of display segments
See § 03.12.13. It is usually possible for any key-switch
combination not described previously.
