Automatic Compensation For Cable Resistance; Automatic Compensation Of Current Measurement Zero; Manual Selection Of Ac Or Dc Mode; Selections Possible In Continuity Function - Gossen MetraWatt METRAclip 72 Mode D'emploi

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 or 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 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.

3.12.6 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.

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 symbol flashes.
P
The selected configuration is memorised when the key is
released: the symbol remains lit continuously.
P
The unit returns to automatic stop mode when the switch
goes to the OFF position.
