MI 3205 TeraOhm XA 5kV

Communication

6 Communication

The instrument can communicate with the HVLink PRO PC software. The following
action is supported:



Saved results can be downloaded and stored to a PC.

A special communication program on the PC automatically identifies the instrument and
enables data transfer between the instrument and the PC.
There are three communication interfaces available on the instrument:

USB, RS 232 or Bluetooth.

How to transfer stored data:



RS 232 communication: connect a PC COM port to the instrument RS 232
terminal using the RS 232 serial communication cable.



USB communication: connect a PC USB port to the instrument USB connector
using the USB interface cable.



Switch on the PC and the instrument.



Set the desired communication port RS 232, USB or Bluetooth.



Run the HVLink PRO PC software.



The instrument is prepared to download data to the PC.

Note:



USB drivers should be installed on PC before using the USB interface. Refer to
USB installation instructions available on installation CD.



Bluetooth communication device pairing code NNNN.
