4.4 Instrument connections

4.4.1 External power

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 (No. 5 in
supply socket.
Note: When the instrument is connected to an external power source, the internal battery pack is automatically
recharged.
4.4.2 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

4.4.3 USB connection

The USB connection (No. 4 in
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.

4.5 Connecting sample lines

Measurements can be taken on a continuous or sample by sample basis. In either mode, the
instrument must be connected to the sample line as follows:
1. The sample inlet and outlet connections on the instrument are located on the ON/OFF sample
flow valve (No. 2 in
1 Sample inlet
2. Connect the inlet and outlet tubing to the sample source and to the drain, respectively. The
diagram above, shows the valve in the OFF position. To turn the sample flow fully ON, turn the
valve counter-clockwise until it clicks into position (about 1/8th of a turn). To remove any residual
air bubbles from the sample line, turn the valve to the PURGE position for 5 seconds before
turning to the ON position.
Note: A length of stainless steel tubing is supplied in the tool kit (4mm instrument version only) and can be
used instead of the plastic tubing on the outlet valve if the pressure in the instrument is high enough to cause
excessive movement of the plastic tubing.
3. If the sample contains particles, it is recommended to use a filter on the inlet tube to avoid any
clogging of the sample flow. The filter (including a box of 10 meshes) is contained in the tool kit
supplied with the instrument. It is also available separately as spare part number DG33216 (4mm
instrument), DG33317 (6mm instrument) or DG33318 (1/4 inch instrument) and the set of
10 meshes as spare part number DG33217.
