HX0034
(Cat. #2124.77)
Probix current
clamp adapter
The HX0034 accessory is a current clamp using a Hall-effect cell to
measure DC or AC currents up to 80A peak, without any intervention on the
electrical installation (cutting off the current to be measured).
A voltage output transducer, this clamp is a "PLUG and PLAY" element. Its
internal electronics are powered by the oscilloscope.
The action generated by the pushbuttons (A and B) can be programmed via
the menu "Green"

"Probix". Use the third push-button (Offset) to
adjust the residual offset (see below).
The measurement output is totally insulated.
Utilization
1. Connect the clamp to the oscilloscope: it is recognized by the
instrument and the measurement unit is displayed in A/div. on
screen.
2. Adjust the offset by pressing the "Offset" button.
The offset can only be adjusted when no current is present.
However, the presence of a DC current is permitted. In this case,
the offset will be obtained in relation to this initial current.
3. Use the trigger to open the jaws of the clip and then insert the
conductor, respecting the current direction.
4. Close the clamp. Make sure that it is properly closed and centered
on the conductor for optimum measurement accuracy.
When the HX0034 probe is connected to the OSCILLOSCOPE, the
following information is displayed.
This information may be different if other PROBIX probes are connected.
