 Never connect to the circuit to be measured if the clamp
box is not properly closed.
 Before any measurement, check the proper positioning
of the cables and switch.
 When measuring current check for proper alignement
of the conductor in relation to the markers and proper
closing of the jaws.
 Always disconnect the clamp from any power source

3.7 INRUSH function
§ 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)
Implementation
This function is accessible in AC current measurement only, after selection of the MIN/MAX mode.

Note 3:
The measurement principle is ased on a certain frequency sta ility and practically sinusoidal signals (THD < 10%).
This excludes in particular measurement on power generators whose spin sta ilisation system is too weak to ensure
adequate frequency sta ility.
3. 2 Secondary Functions
3. 2. Display lock
A short pressing on the HOLD key freezes the display.
A second pressing unlocks the display.
3. 2.2 Preselection of MIN/MAX mode
A short pressing on the HOLD key then on the MIN/MAX key preselects the MIN/MAX mode. A second pressing
on the HOLD key makes the MIN/MAX mode effective.
This function is used to select the MIN/MAX mode upon request to prevent, for example, the unwanted or mistaken
integration of MIN/MAX values.

3. 2.3 Automatic 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 W) this correction is stopped and the memorised correction value is reset to
zero.
This correction is prohibited in MIN/MAX mode.
3. 2.4 Automatic compensation of current measurement 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. 2.5 Manual selection of AC, DC or AC+DC mode
By default the clamp switches to AC or DC mode automatically 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 of compound
signals AC+DC) and return to automatic mode. When the mode is selected manually, the AC, DC or AC+DC symbol is
fixed. The selection of this manual mode is impossible in MIN/MAX or HOLD mode.
3. 2.6 3. 2.6 Selections 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 W), then the semi-conductor test function )
and return to the continuity function )
3. 2.7 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. 2.8 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 symbol flashes. The selected configuration is memorised when the key is released: the
symbol remains lit continuously. The unit returns to automatic stop mode when the switch goes to the OFF position .
Lapparecchio emette un duplice bip quindi il simbolo lampeggia.
La configurazione scelta viene memorizzata quando si rilascia il tasto : il simbolo è acceso fisso.
Lapparecchio ritorna in modo arresto automatico quando il commutatore passa sulla posizione OFF.
3. 2.9 Activation of the V-Live function
Hold the HOLD key pressed and bring the rotary switch from the OFF position to the V position.
The unit emits a double beep then the V and symbol flashes.
The selected configuration is memorised when the key is released: the V symbol is then ON steady and the symbol
flashes. Proceed in the same way to suppress the V-Live function: the symbol then goes OFF when the key is
released.
3. 2. 0 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 W and symbols go ON along with the threshold value 40.0 by default). Adjustment is then possible
from 1 W to 40 W by successive pressings on the yellow key short pressure: progression of 1 W by 1 W; press and hol
hold: progression of 10 W by 10 W). Once the value is chosen, actuate the rotary switch to memorise.
3. 2. 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 W
- Auto cut-off: with
- V-Live function: none
3. 2. 2 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 V position.
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. 2. 3 Display of the internal software version
Hold the HOLD key pressed and bring the rotary switch from the OFF position to the A position . 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. 2. 4 Showing of display segments
See § 03.12.13. It is usually possible for any key-switch combination not described previously.
