Preselection Of Min/Max Mode; Automatic Offset Of Lead Resistance; Automatic Zero Offset When Measuring Current; Manual Selection Of Ac Or Dc Mode - Chauvin Arnoux F 03 Notice De Fonctionnement

3.8.2 Preselection of MIN/MAX mode

MIN/MAX mode is preselected by a short press on the HOLD
key and then on the MIN/MAX key. MIN/MAX mode is then
activated by pressing on the HOLD key.
This function allows MIN/MAX mode to be selected when
required, to avoid for example, the inclusion of untimely or
erroneous MIN/MAX values

3.8.3 Automatic offset of lead resistance

To offset lead resistance, hold the HOLD key down when the
continuity test or resistance measurement function is selected.
When the key is released, once zero is displayed, the
correction value is saved in the clamp.
If the value measured is over 2 Ω Ω Ω Ω Ω , this correction is inhibited
and the value of the correction saved is reset to zero.
This correction is inhibited in MIN/MAX mode.

3.8.4 Automatic zero offset when measuring current

To offset the zero, hold the HOLD key down when current
measurement function is selected.
When the key is released, once zero is displayed, the
correction value is saved in the clamp.
If the value measured is over 6 A, this correction is inhibited
and the value of the correction saved is reset to zero.
This correction is inhibited in MIN/MAX mode.

3.8.5 Manual selection of AC or DC mode

The clamp defaults automatically to AC or DC mode (AC or
DC symbol flashes) for V and A functions.
A series of short presses on the yellow key allows alternating
(AC) and continuous (DC) measurement to be selected
manually and to return to automatic mode.
When the mode is selected manually, the AC or DC symbol
is continuous.
It is impossible to select manual mode in MIN/MAX or HOLD
modes.

3.8.6 Selections possible in the continuity function

By default, the clamp is set to the continuity function ( ) for
the corresponding position of the switch.
With a series of presses on the yellow key, the user can select
resistance measurement (Ω) then the semi-conductor test
function ( ) and then return to the continuity function ( ).
3.8.7 Choice of units (°C or °F) when measuring
temperature
The unit can be chosen from the temperature function by a
short press on the yellow key, which allows °C or °F to be
selected as required. The unit is not saved when the clamp is
turned off. See § 3.8.8 to save the unit to memory.
