6.3. Current measurement with a clamp-on-adapter
1. Connect the black test lead of the clamp-on-adapter with the COM
terminal and the red test lead of the clamp-on- adapter with the µA,mA
terminal.
2. Embrace the positive/phase cable with the measurement clamps
3. Read the measurement value from the display
Note:
*
The conversion when using a current clamp adapter is a factor 1A per
1mV. Therefore we recommend to use only current clamps with the
same conversion factor. When using an adapter with a different factor
(1A/10mV) this factor must be calculated to the measurement value
manually by the user.
*
Never attach the clamps to the complete cable, because the magnetic
field between phase / neutral and plus / minus cancels each other and
therefore no measurement result will be displayed.
*
A minus-symbol in front of the reading shows a negative DC-Voltage.
The minus-symbol disappears when measuring a positive voltage
