GasClam 2 Configuration and Setup
Software
Installation
The GasClam 2 software will run on: Windows XP SP 2, Windows 7, Windows 8.0 and 8.1.
The GasClam 2 software is on the CD (latest version can be provided by your service centre), it includes an
installation package with .Net Framework 4 (x86) (downloadable also from the Microsoft website) and a PDF
manual. The software needs 45 MB of free space on the hard disk for installation.
WARNING
: All connections between the GasClam and a PC and all software settings must be performed outside
the hazardous areas.
Function
The software is used to configure the GasClam 2 for logging, downloading logging data, performing analysis and
exporting data for more detailed analysis in other programs such as spreadsheets. The software is also used to
perform periodic “Bump Test” and “User Calibration”.
The main settings are the logging interval, variable logging interval
programme, the number of samples (sample count), the outlet gas
venting method and whether a borehole water level sensor is fitted.
To help make data analysis easier the software can set each GasClam 2
a
“friendly” name. If more than one
GasClam 2 is being used on a
monitoring site it is good practice to also label each GasClam 2 so that
they are not put in the wrong boreholes.
Power Supply Options
The GasClam 2 can use 4 approved power sources:
•
2x 1.5 V Alkaline-Manganese Duracell - MN1300 (Alk-Mn)
(logging interval 3 minutes to 24 hours)
•
2.6 V Nickle Metal Hydride rechargeable battery pack (Ni-MH)
(logging interval 3 minutes to 24 hours)
•
7.2 V Lithium non-rechargeable battery pack (Li)
(logging interval 15 minutes to 24 hours)
•
12 V External dc power supply (Ext)
(logging interval 3 minutes to 24 hours)
The GasClam 2 can operate as either a stand-alone logger or linked to a data acquisition system.
The Ni-MH battery packs are rechargeable lasting up to a month with a 1-hour logging interval. The Li packs are
non-rechargeable primary cells that can last up to 3 months with a 1-hour logging interval. The lifespan of individual
types of battery packs depends on the logging interval, GasClam 2 sensor configuration, operating temperature
and for rechargeable packs in particular, age and time since they were last charged.
An external power supply is particularly useful if shorter logging intervals are required (sampling up to every 3
minutes) when a battery pack would not last a month and frequent site visits are not feasible. This option is also
advantageous if remote monitoring is required either using the optional modem (which can also be powered
externally) or external telemetry (s
ee section “External Power”). Note: Moisture Filter life is dependent on logging
interval.
The GasClam 2 will automatically select the power source and adjust accordingly (see Software Manual).
