3.12 Secondary Functions

3.12.1 Display lock

A short pressing on the HOLD key freezes the display.
A second pressing unlocks the display.

3.12.2 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.

3.12.3 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 Ω Ω Ω Ω Ω , this correction
is stopped and the memorised correction value is reset to
zero.
This correction is prohibited in MIN/MAX mode.
3.12.4 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.
3.12.5 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.

3.12.6 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 (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.
