2.2.1 Serial number
The sensor's serial number can be found on the label affixed to the
side of the instrument. You should quote this serial number if you
ever need assistance from Güralp Systems.
2.3 Connection
The instrument is supplied with a 26-way cable with mil-spec bayonet
connectors on each end; this carries both power and output signals
and is suitable for connecting directly to a Güralp digitizer.
An optional breakout box, if ordered, provides individual signal and
power connectors, or you can make up your own cable if you prefer.
2.3.1 The breakout box
If you are using the optional Güralp breakout
box, the data cable from the instrument should
be attached to its SENSOR connector.
Connectors are also provided at the CONTROL
and RECORDER outputs, for attaching to an
optional hand-held control unit or a Güralp
digitizer.
The breakout box also provides a standard
Güralp power connector on a 10-pin mil-spec
plug. The 6T draws a nominal current of 38 mA
from a 12 V supply when in use; thus, using a
12V, 25 Ah sealed heavy-duty lead-acid battery,
you should expect the instrument to operate for
around a week without recharging.
The CENTRE button switches the instrument into one-second mode
whilst it is pressed. This mode allows you to monitor the mass
