Buffers should therefore be minimised. Using the Device Manager of your computer's
Windows Control Panel, select the port to be used and select: Port Settings\Advanced\. Set
the Receive Buffer and Transmit Buffer to Low (1).
4. MS2 Meter Settings.
Check the rotary switch on the rear panel of the MS2 meter. This switch
controls the serial baud rate and format of the data. Using a screwdriver, the switch should
be set as follows:
•
for operation with Multisus2 or Bartsoft, set to position A
•
for an X/T system running under GeoLab, set to position B
•
for operation with a Geotek conveyor system, set to position C.
5. Multisus2.
Use the menu item Serial Port\Set Baud Rate and Port to select the port to
which the MS2 meter is connected. Select 1200 baud as the rate. Select Serial Port\Test
Communications to check the zero setting and receipt of the meter measurements by the PC.
The meter should normally be switched on when prompted by the program to ensure that
any invalid characters transmitted by the meter at switch-on are cleared from the PC input
ports.
6. Cables.
Newer meters will have been supplied with a single cable from the MS2 meter to
a 9-pin D-type RS-232 connector for direct connection to a computer or RS-232-to-USB
adaptor. Earlier meters will have a cable with a 25-pin connector, a 25-pin to 9-pin adaptor,
and 9-pin to 9-pin cable. It is necessary to use all three components for correct operation.
Similarly, the X/T system is supplied with labelled cables for connection and these special
cables must be used.
7. Battery.
If the MS2 meter internal battery is discharged, the first effect will be to produce
random noise in the readings. If the battery becomes further discharged then it may cause
the serial communication to fail. To maintain the battery in good condition it should be
completely discharged, at six-monthly intervals, by leaving the meter running with a sensor
connected, and then recharged for 48 hours with the meter switched off. Eventually the
battery will require replacement: see
Replacing the MS2 Meter Battery
.
Note:
When running the meter with the serial output connected, leave the mains adaptor
switched on and charging the battery whenever possible.
22. Storage and Transport
The MS2 system is a precision electronic instrument and should be treated as such.
Bartington Instruments supplies its products in appropriate packaging for transporting. This
packaging should be used for any future transport.
