Connection Procedure
For instructions on how to connect a particular logic probe, see its user’s manual.
Make sure to turn off the power to the DLM6000 before connecting or disconnecting a logic probe
cable.
Note
If the logic probe is not connected to the DLM6000, the logic probe input is at low level.
