Installation
3.7 Instrument connections
3.7.1 External power
WARNING
When using an external power supply to power the instrument, ensure the external
power socket is earthed.
In addition to the internal rechargeable battery pack, the instrument can be powered by an
external power source using the supplied adapter and cable. Connect the adapter to the power
supply connection socket on the instrument (in Figure 4 on page 14), and plug into an external
power supply socket.
Note: When the instrument is connected to an external power source, the internal battery pack is
automatically recharged.
3.7.2 RS232 connection
This connection can be used to download measurement data and for real-time monitoring of the
measurements.
The data sent to the PC via this link is identical in format and content to that stored in the
measurement file on the instrument and which can be transferred using the USB mass storage
device (see Exported files on page 36 for details).
3.7.3 USB connection
The USB connection (in Figure 4 on page 14) is used for exporting and importing data from and
to the instrument. Tables can be set up on the PC using the 3100 PC software application and
then uploaded to the instrument using a USB mass storage device.
In addition, tables can be exported from the instrument to the USB storage device and then
imported to other 3100 instruments to standardize configurations.
For more details on this, refer to Import / Export on page 35.
