EMCtools – lab life made easyCurrent Sensor
Introduction and use:
The EMCtools Current Sensor-Set offers new possibilities in automotive EMC susceptibility tests.
It provides a galvanic insulated DC current measurement for DUT supervision or failure detection. High rated measurement
current and extreme low voltage drop come together with high resolution and good accuracy. The measurement head has
been tested for field strength of >270V/m.
The built in battery allows measurement in pos. or neg. battery line. It can be recharged by connecting it to a USB connectorof any available PC or notebook.
The current data is transferred to the control unit using a standard simplex fiber optic F-SMA cable.
The control unit displays the current on a display. A trigger signal can be generated to trigger Oscilloscopes or to control thesusceptibility test depending on various current situations.
A CAN-bus interface provides the measured current permanently or when triggered on HS-CAN or LS-CAN. CAN-bus, CANspeed and CAN-identifier can be set individually.
The measured current data is also available via USB.
A built in USB to CAN interface can be used to send EMC related data like test frequency or field strength etc. to CAN bus.
All settings and options can be made locally using a menu rotary switch or via remote commands (USB).
Settings are stored in non volatile memory.
