Metrix HX0034B Manual De Instrucciones página 6

Pushbuttons A and B can be programmed using the vertical
-
menu of the SCOPIX oscilloscope to activate commands.
Example: incrementation/decrementation of the vertical
sensitivity, the time base, display of the automatic
measurements, etc. Refer to the user's manual of the
SCOPIX oscilloscope.
The "Offset" automatically calibrates the zero DC of the
-
clamp. The end of this process is indicated by an audio
"beep" from the oscilloscope. In "Multimeter" mode, SCOPIX
eliminates the residual current.
4. Implementation
Do not use the clamp outdoors.
-
Do not exceed 300 V (Cat. III) or 600 V (Cat. II) in relation to
-
the earth of a non-insulated conductor (double insulation).
Use the clamp on conductors in which the current is less than
-
or equal to the maximum value in continuous operation, i.e.
80 A peak.
Protect the clamp against falls and splashing with water.

5. Use
1. This clamp must be connected to the associated oscilloscope
before performing any current measurements. It must not be
disconnected during measurement.
2. Connect the clamp to the oscilloscope: it is recognized by the
instrument and the unit is displayed in A/div. on the SCOPIX
oscilloscope's screen.
Adjust the offset by pressing the "Offset" button.
3.
The offset can be performed only without current. However,
the presence of a DC current is accepted. In this case, the
offset will be performed in relation to this initial current.
4. Use the trigger to open the jaws of the clamp and then place
them around the conductor, taking into account the current
direction.
5. Close the clamp. Make sure that it is properly closed and
centred on the conductor for optimum measurement
accuracy.
